Symmetric-key cryptography

desirable property of cryptographic algorithms, typically block ciphers and cryptographic hash functions, wherein if an input is changed slightly, the output changes significantly

cryptographic protocol

form of encryption which simultaneously provides confidentiality, integrity, and authenticity assurances on the data

properties of the operation of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography

method of bit-shuffling used to diffuse bits across S-boxes

property of cryptographic hash functions

length of bit string processed by a cipher function
