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. … WebApr 15, 2024 · Most of the security analysis of symmetric primitives is actually based on their representation and not on the primitive itself: When arguing about the resistance of ciphers or cryptographic permutations, our arguments are in most cases based on a given decomposition of the cipher, in many cases into a linear layer and a set of mappings that …
