The Secure Sockets Layer and Transport Layer Security. Ever since Netscape Communications invented the Secure Sockets Layer Protocol (SSL) in 1994, after the Internet becomes under scrutiny over security, the arms race between code breakers and code makers has been accelerated in the field of the internet cryptography.

Report Abuse. An autotroph is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions. Autotrophs are the producers in a food chain. Plants and other organisms which carry out photosynthesis are photoautotrophs (or phototrophs).Bacteria which derive energy from oxidizing inorganic compounds (such as hydrogen sulfide, ammonium and ferrous iron) are chemoautotrophs, and include the lithotrophs.hey take energy from the environment (in the form of sunlight or inorganic chemicals) and use it to create carbon-based organic molecules. Other organisms, called heterotrophs, take in autotrophs as food to carry out such functions.
