Cryptographic primitives definition
WebOne-way permutations are an important cryptographic primitive, and it is not known that their existence is implied by the existence of one-way functions. A collision-free hash function f is a one-way function that is also collision-resistant ; that is, no randomized polynomial time algorithm can find a collision - values x , y such that f ( x ...

WebJun 13, 2024 · In principle, a crypto primitive (or protocol) provides security against an adversary mounting some particular form of attack where the nature of the attack depends on the type of primitive being considered. Attacks are usually specified in the form of a game between an adversary and honest parties. WebApr 15, 2024 · Laconic cryptography is an emerging paradigm that enables cryptographic primitives with sublinear communication complexity in just two messages. In particular, a two-message protocol between Alice and Bob is called laconic if its communication and computation complexity are essentially independent of the size of Alice’s input.
Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. …
