Services is a suite of Web services for customers with integration and business-to-business collaboration requirements . These services include workflow , access control , and service bus connectivity — enabling developers to extend applications to the cloud through a flexible , scalable and interoperable platform . The notion of attribute-based encryption ( ABE ) was proposed as an economical alternative to public-key infrastructures . It is the set of descriptive attributes , used as an identity to generate a secret key , as well as serving as the access structure that performs access control . ABE is also a useful building block in various cryptographic primitives such as searchable encryption . . Access control is essential to computer security , especially in an open , distributed , networked communication environment . Modern access control model such as UCON aims at accommodating general requirements . Security services in a multi-user environment are often based on access control mechanisms . Static aspects of an access control policy can be formalised using abstract algebraic models . We integrate these static aspects into a dynamic framework considering requesting access to resources as a process aiming at the prevention of access control violations when a program is executed . In order to enhance the mediating ability of Service Integration Bus and promote the service quality of Service Oriented Architecture and guarantee the safety of Distributed System , a lot of work and extensions have been done on eXtensible Access Control Markup Language which can be used to specify not only access control policy but also route selecting policy . Considering access control policy and route selecting policy , an Attribute-Based Policy Service has been designed for SIB which will have the ability of smart routing and access control . Furthermore , an improved model of Policy Repository has been put forward to increase the efficiency of policy decision . Computer Security And Safety . A Propositional Logic For Access Control Policy In Distributed Systems M. Kurkowski , J. Pejas . Providing a secure cloud environment from the malicious user is one of the important and challenging tasks among scientific and business user community . Over the time , various control access models have been proposed for secure access in the cloud environment such as cryptographic-based access model , identity-based access control model and trust-based access control model . The users and cloud resources should be trusted before accessing the cloud . Nowadays , many security features are available . We can cite for instance cryptographic protocols , management infrastructures of public keys ( PKI ) , firewalls , control access mechanisms within operating systems and applications , intrusion detection systems or anti-viral mechanisms etc . The embodiment of the invention discloses an access controlling method , equipment thereof and a system thereof . The method comprises the following steps of : a terminal receives accesses controlling information , wherein the accesses controlling information comprises a probability threshold for prohibiting the terminal from accessing a circuit switch feedback CSFB service , and the terminal ensures that the access of the CSFB service is failing when the access probability factor selected by the terminal is larger than the probability threshold or the accesses controlling information comprises an instruction for prohibiting the terminal from accessing the CSFB service ; or the accesses controlling information comprises a probability threshold for prohibiting the terminal from accessing a circuit switch feedback CSFB service , and the terminal sends a RRC connection request when the access probability factor selected by the terminal is less than and equal to the probability threshold or the accesses controlling information comprises an instruction for allowing the terminal to access the CSFB service . Isolation of tasks to manage the ever-changing and strict mixed-criticality MPSoC operation is mandatory . Hardware-based firewalls are an effective protection technique to mitigate attacks to MPSoCs . However , the fast reconfiguration of these firewalls impose a huge performance degradation , prohibitive for critical applications . The prior art has investigated ways to protect mobility data by providing a wide range of Location Privacy Protection Mechanisms ( LPPMs ) . However , the privacy level of the protected data significantly varies depending on the protection mechanism used , its configuration and on the characteristics of the mobility data . Meanwhile , the protected data still needs to enable some useful processing . To do so , we introduce a formal model of privacy called k-unlinkability , and several configurable algorithms to render protected trails . To satisfy real world policy constraints , we present a novel secure multiparty computation protocol that embeds the protection procedure . Using real world datasets , it is demonstrated that significant quantities of data can be disclosed with provable privacy guarantees . With the information recovered from the wrist movements perceptible by a smartwatch , we exemplify the risks associated with unaudited access to seemingly innocuous sensors ( e.g. , accelerometers and gyroscopes ) of wearable devices . As part of our efforts towards preventing such side-channel attacks , we also develop and evaluate a novel context-aware protection framework which can be used to automatically disable ( or downgrade ) access to motion sensors , whenever typing activity is detected . The paper will show a possible model for surveillance systems moving beyond current commercial products ’ way of operation . While currently alarm systems merely offer the possibility to switch the full protection on and off , this work proposes a more context aware protection , that tailors itself to the different situations that may take place in a home environment , and a set of smart behaviours to define the best reaction to each event , in order to introduce a novel working model for security systems : an always on operating mode where it ’s up to the system and not to the user the responsibility to determine whether protection is needed or not . To accomplish this , raw sensor data will undergo a pattern recognition process , where the system gains knowledge even of complex situation , inferring from dataflows coming from the environment ( through statistical analysis , artificial intelligence and possibly machine learning ) . Disclosed is an impacting device equipped with a protective plate . The impacting device equipped with a protective plate comprises an impacting power apparatus and an impacting head , wherein the impacting head comprises an impacting head protection apparatus , the impacting head protection apparatus comprising a toothed frame and a protection member , and the impacting head further comprises impacting teeth . The protection member is distributed all around the toothed frame or distributed at a part thereof . The model of current comparison pilot protection is built on the Simulink platform of MATLAB , and the GUI interface design is completed . The simulation is carried out after setting the interface parameters , and the simulation waveforms are analyzed , which verified operation characteristic of current comparison pilot protection . Because of a failure to take proper actions for the system to recover , this voltage stability problem evolves into an angle stability problem . New monitoring , protection , and communications technologies allow us to implement economical localand wide-area protection systems that minimize risk of wide-area system disruptions or total system collapse . An error sensitivity aware slicing scheme is proposed to enable the use of unequal error protection techniques in order to offer better protection to the more important packets . Experimental results justify the validity of the proposed priority based protection scheme . Abstract Integration of the Distributed Generators ( DGs ) in the MicroGrid ( MG ) provides an additional contribution to the fault current causing change of the short circuit current which could lead to the miscoordination problem ( in the forms of maloperation and delayed operation ) in the existing Over Current Relay ( OCR ) based protection system . Moreover , contribution of the MG can cause the overall fault current to exceed the designed capability level of distribution components , like Circuit Breakers ( CBs ) . The present invention discloses a power failure protection devices and rotary tower crane , comprising a battery , a first switch , a second switch , turning the motor brake coil circuit , and the freewheeling circuits breakwater emergency power failure protection circuit , the rotary motor brake coil circuit , the freewheeling circuit and the loss of the breakwater protection circuit is provided in parallel to the emergency ; a negative electrode of the battery are connected to the breakwater freewheeling circuit input and a rotary motor brake coil circuit output terminal , the anode of the breakwater are freewheeling circuit outputs end and a rotary motor brake coil circuit input terminal ; a first switch is open when the tower crane is working properly , automatically closes after loss of power ; second switch is closed when the tower crane is working properly , the loss of power to open delay ; loss electric emergency protection circuit for a sudden loss of power when the tower crane , tower cranes disc brake state is maintained at the gate opening . After having a sudden power the swing mechanism automatically safe and fast soft stop to avoid a collision and advantages of the machine shocks . The main efforts have been focused on development of new artificial neural network ( ANN ) based and mixed protection techniques which should ensure better ( faster and more secure ) detection of generator loss of synchronism . The designed AI-based OS protection schemes have been thoroughly optimised and tested with EMTP-generated case signals . Wide robustness analysis as well as comparison with chosen standard OS detection method have also been performed . The invention provides a board card type packet microwave device and a microwave link 1 + 1HSB protection method and relates to the technical field of packet transmission device warning detection and control . The device comprises a packet transmission device and a microwave device . The CNIL ( French Data Protection Authority ) advises owners of connected speakers to switch off the microphone when possible and to warn guests of the presence of such a device in their home . The General Data Protection Regulation which harmonizes data privacy laws across the European Union indeed requires companies to ask for explicit consent before collecting user data . Some of the most popular commercial solutions for voice assistants include Microsoft ’s Cortana , Google ’s DialogFlow , IBM ’s Watson , or Amazon Alexa . Logic locking is a promising defense technique against such malicious activities that is effected at the silicon layer . Over the past decade , several logic locking defenses and attacks have been presented , thereby , enhancing the state-of-the-art . Our attack does not require a working copy and yet we successfully recover a significant fraction of key bits from the design of the locked chip only . Empirically , we demonstrate the success of our attack on eight large benchmark circuits from a benchmark suite that has been tailored specifically for logic synthesis research , for two different logic locking schemes . Then , to address this vulnerability , we initiate the study of provably secure logic locking mechanisms . In this paper , we introduce DFSSD , a novel logic locking solution for sequential and FSM circuits with a restricted ( locked ) access to the scan chain . DFSSD combines two techniques for obfuscation : ( 1 ) Deep Faults , and ( 2 ) Shallow State Duality . In this paper , we introduce SCRAMBLE , as a novel logic locking solution for sequential circuits while the access to the scan chain is restricted . The SCRAMBLE could be used to lock an FSM by hiding its state transition graph ( STG ) among a large number of key-controlled false transitions . It is shown that existing systems commit these errors while PL does not . While other logical locking systems are limited in the complexity of permissible predicates , PL allows them to be arbitrary . It is shown that transactions under PL are well formed and two phased which is sufficient to maintain consistency . Logical locking is the most popular countermeasure against the hardware attacks like intellectual property ( IP ) piracy , Trojan insertion and illegal integrated circuit ( IC ) overproduction . The functionality of the design is locked by the added logics into the design . The attack process starts with analyzing design features that are generated from the synthesis tool and establishes a correlation between these features and the correct key values . In order to perform the attack , the logic locking tool needs to be available . The level of accuracy of the extracted key mainly depends on the type of logic locking approach used to obfuscate the IP . The LogicLock method based on Altera FPGA can highly improve design efficiency of complex system . The performance of each module can be preserved during system integration . As part of this development , embedded security has become an increasingly important issue in a multitude of applications . Examples include the Stuxnet virus , which has allegedly delayed the Iranian nuclear program , killer applications in the consumer area like iTunes or Amazon 's Kindle , the business models of which rely heavily on IP protection , and even medical implants like pace makers and insulin pumps that allow remote configuration . These examples show the destructive and constructive aspects of modern embedded security . Now we take up what is , arguably , the most difficult and potentially expensive information security problem of all : protection of intellectual property . The difficulties associated with IP protection are significant . And they are matched directly by the impact of IP compromise . An implementation using the Virtex-4 device from Xilinxreg is demonstrated to illustrate the low complexity cost . A refinement of the IP exchange scenario for the proposed IP-protection system is also included in this paper Network survivability has become one of the most important QoS ( Quality of Service ) parameters in IP network-based applications , particularly with regard to real-time multimedia applications . IP-based protection that enable recovery from failure in just a few milliseconds can provide greater network resilience than traditional routing recovery or other lower-layer recovery technologies . This paper proposes an IP protection scheme , called IP Local Fast-Reroute ( IPLFRR ) , for single node or link protection . This scheme works in an intra-area routing domain , providing a simple and efficient solution to improve the survivability of IP networks . that are needed to make this script run are simultaneously installed . On the other hand , IP-based protection uses IP network prefixes as cypher keys . A script language is used as a proof of concept . With its reprogrammability , low design cost , and increasing capacity , field-programmable gate array ( FPGA ) has become a popular design platform and a target for intellectual property ( IP ) infringement . Currently available IP protection solutions are usually limited to protect single FPGA configurations and require permanent secret key storage in the FPGA . In addition , they can not provide a commercially popular pay-per-device licensing solution . With the rapid development of virtual economy , infringement disputes in intellectual property rights ( IP ) such as film and television , games , creativity and so on frequently appear . The market urgently needs effective IP protection solutions . There are many problems in the traditional way , and blockchain technology has produced a subversive innovation in IP protection , and thoroughly solve the IP protection problem . According to the installation requirements , the monitoring terminal structure is designed . According to the protection requirements , IP protection design and electromagnetic compatibility simulation are carried out . The monitoring terminal uses current transformer to take on-line energy while cooperating with battery energy . What are the technical challenges to be addressed ? What EDA technologies will work : embedding IP protection measures in the design phase , developing rapid post-silicon certification , or counterfeit detection tools and methods ? Security is the main concern and a challenging problem of Web services . In the recent years , XML-sensitive security appliances , such as XML firewalls or Web service firewalls , have been introduced to protect services . However , attackers can still compromise web services and do their malicious actions . Security mechanism like traditional firewalls even lots of web application firewalls ca n’t protect service oriented architecture environment against attacks . Firewalls namely XML firewalls are responsible for providing security of this environment . These firewalls in the first step should be aware of content of SOAP message and XML and can protect Web Services against attacks . You can not think of secure network without using firewall . Already layer 2 and stateless firewalls are available in SDN but the main issue is that can we implement stateful firewall that keeps connection tracking information . In this paper we are implementing SDN stateful firewall using POX Controller . In prior work [ 1 ] , we proposed and evaluated a technique to remotely discover the last matching rules of the Linux Netfilter firewall . In this paper , we examine the effectiveness of such technique on the discovery of last-matching rules in two other popular open-source network firewalls , namely Linux IPSets and FreeBSD ipfw . Firewalls themselves can become target of DoS attacks . In a prior work ( Salah et al. , 2009 ) , we studied the resiliency and robustness of open-source network firewalls against the remote discovery of the last-matching rules . If last-matching rules are discovered , an attacker can launch an effective and slow-rate DoS attack which can bring down the firewall to its knees . Nowadays enterprises are looking for efficient security devices , like Intrusion Detection Systems ( IDS ) , to supplement the firewalls supervision . Nevertheless , IDS are plugged with several problems that slow down their development : the high speed traffic and the increasing number of attack detection rules . Wir stellen zweitens das Konzept eines dynamischen Firewalls ( dynamischer IP-Filter ) vor , der Internetverbindungen aufgrund gesicherter Daten ( Digitale Signaturen und Zertifikate ) durchschaltet . In herkömmlichen Firewalls fallen sicherheitsrelevante Entscheidungen bisher meist anhand von ungesicherten Daten ( IP-Adressen und Portnummern ) , wodurch bestimmte Angriffsmöglichkeiten nicht abgewehrt werden konnten . Gartner 's figures and other similar studies show the failure rate hovering at a plateau of 50 % for data warehouses since 2004 . While the true cause of poor data quality can be attributed to a lack of supporting business processes , insufficient analysis techniques , along with protecting oneself with the introduction of data quality firewalls for incoming data , the question has to be raised as to whether a data quality assessment of the existing data would be worthwhile or plausible ? This paper defines a data quality assessment model that enables a methodology to assess data quality and assign ratings using a score-card approach . Firewalls are located at the front line of the network against outside threats . Performance modeling and analysis of network firewalls help to better understand their behavior and characteristics . Moreover , having an analytical model in hand helps firewall designers avoid developing multiple design alternatives and thus considerably reduce the design costs . The wireless “ WiMAX ” based protection “ W-Protection ” is a new concept for protecting multi-zones as one unit zone using coordination logic . The W-Protection produces new protection solution to properly identify the faulted zone using the wireless networks such as the IEEE 802.16 based WiMAX technology . The IEDs communication traffic requirements and the application models that map them over the real time polling service ( rtPS ) and unsolicited grant service ( UGS ) scheduling services of the IEEE 802.16 standard are extensively studied . Attackers use thevulnerability of stack overflow to write long data in internal storage which make it beyond its buffer capacity , cover the return address , and thus transfer to the attacker 's malicious control flow . To defend this type of attack , the operating system was added with W + X protection mechanisms , viz.dataExecution Prevention ( DEP ) . The hardware was realized by IntelXD(Execute Disable bit)technology , ND(No-Execute Page-Protection ) of AMD technology and XN(eXecute Never ) ARMtechnology . Since the day it was proposed , return-oriented programming has shown to be an effective and powerful attack technique against the write or execute only ( W xor X ) protection . However , a general belief in the previous research is , systems deployed with address space randomization where the executables are also randomized at run-time are able to defend against return-oriented programming , as the addresses of all instructions are randomized .

However , a general belief in the previous research is , systems deployed with address space randomization where the executables are also randomized at run-time are able to defend against return-oriented programming , as the addresses of all instructions are randomized .
