WebRemember, in CBC-MAC, the block cipher F is applied at the very end with an independent key, Fk . In the lecture, I presented an attack when the key ki is the same as k for each block. Suppose now that instead of appending Fk, we apply it twice, Fk, and then again Fk, Now for this case present an attack, similar to the one I constructed, when k ...

WebMar 13, 2024 · Data encryption standard (DES) has been found vulnerable to very powerful attacks and therefore, the popularity of DES has been found slightly on the decline. DES is a block cipher and encrypts data in blocks of size of 64 bits each, which means 64 bits of plain text go as the input to DES, which produces 64 bits of ciphertext.
