Cryptographic primitives

mathematical scheme for verifying the authenticity of digital documents

cipher that works on fixed-size blocks of bits

special class of hash function that has certain properties which make it suitable for use in cryptography

symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream

function that is easy to compute on every input, but hard to invert given the image of a random input

A form of encryption that allows computation on ciphertexts

type of function that is easy to compute in one direction, yet difficult to compute in the opposite direction without special information

pseudorandom number generator with good statistical randomness and resistance to cryptanalysis

cryptographic concept

cryptographic protocol enabling the sharing of a secret key over an insecure channel
