WebCounting the number of active S-boxes is a common way to evaluate the security of symmetric key cryptographic schemes against differential attack. Based on Mixed Integer Linear Programming (MILP), Mouha et al. proposed a method to accomplish this task automatically for word-oriented symmetric-key ciphers with SPN structures. WebIn a related-key attack, the adversary is allowed to transform the secret key and request encryptions of plaintexts under the transformed key. This paper studies the security of PRF- and PRP-constructions against related-key attacks.

WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit. WebThey suggest a simple way to construct a tweakable block cipher out of a block cipher resistant to related-key attacks: simply xor the tweak into the key.
