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.

WebMar 18, 2024 · The cryptographic primitives are either theoretically broken or practically broken. The assumptions that we made in the proof are the adversary can play the challenge game with the KDFs and at the same time the adversary can exploit the existing attacks towards the cryptographic primitives that are used to build the KDFs. Cryptographic primitives are one of the building blocks of every crypto system, e.g., TLS, SSL, SSH, etc. Crypto system designers, not being in a position to definitively prove their security, must take the primitives they use as secure.
