WebWe saw a general attack on block cyphers which we called exhaustive search. And that attack forced the key size for a block cypher to be 128 bits or more. Similarly on collision resistance there is a general attack called the birthday attack which forces the output of collision resistant hash functions to be more than a certain bound. WebThe Security of a block cipher depends on the key size (k). Therefore the best attack against a block cipher is the exhaustive key search attack which has a complexity of 2 k. However when block ciphers are used to encrypt large amounts of data using modes of encryption such as CBC, the block size (n) also plays a bit part in determining its ... WebAug 18, 2024 · 2.
