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.
The inputs to the encryption algorithm are a plaintext block of length 2w bits and a key K. The plaintext block is divided into 2 halves, L0 and R0. The 2 halves of the data pass through n rounds of processing and the combine to produce the ciphertext block.
