We exploit this by passing in C1' + C2, where C1' is a sneakily chosen ciphertext block, C2 is the ciphertext block we are trying to decrypt, and C1' + C2 is the concatenation of the two. We call the decrypted plaintext block produced P'2. To begin with, we choose C1'[1..15] to be random bytes, and C1'[16] to be 00. port townsend wa city dataWebSep 18, 2024 · As you say: c1 xor c2 = m1 xor m2 if k is the same. In this equation you must know m1 or m2 to recover the other. In real life, note that m1 or m2 are not pseudo random string like G(k). They may be predictable or easy to guess the content. For example, m1 and m2 are both an English sentence or m1 and m2 are both a header of some protocols. port townsend wa breakfast restaurants
