Intermodal transport (or intermodal transportation) involves the use of more than one mode of transport for a journey. See: Intermodal passenger transport; Intermodal freight transport
Encryption algorithms At the heart of every encrypted application is the algorithm, the math that scrambles and unscrambles data. In a nutshell, an encryption algorithm is a function which takes a string of data bytes and returns a new dataset containing unintelligible content. The same algorithm is used to decrypt data, which means encrypted data goes in from one side and the original data comes out the other.
For an overview of cryptographic technology in general, see Cryptography. In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. Encryption does not of itself prevent interference, but denies the intelligible content to a would-be interceptor.
