WebMay 24, 2024 · Attacks on cryptographic hash functions. Attacking a cryptographic hash function implies breaking one of its security properties. For example, breaking pre-image resistance means that an attacker can create a message that hashes to a specific hash [5]. Attacks on hash functions may focus on either the structure of the hash function or on … 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.
