Security of Symmetric Primitives against Key-Correlated Attacks

Security of Symmetric Primitives against Key-Correlated Attacks

We study the security of symmetric primitives against key-correlated attacks (KCA), whereby an adversary can arbitrarily correlate keys, messages, and ciphertexts. Security against KCA is required whenever a primitive should securely encrypt key-dependent data, even when it is used under related key...
