WebTwo same message blocks encrypt to the same cipher blocks 1. Two cipher blocks can be switched 2. One cipher block can be copied to another ex: switch or copy salary block 3. No built-in integrity or authentication check Possible fix: have many keys, one for each block Recurring phrases cause repeated part-blocks of ciphertext WebQuestion. **GIVEN MESSAGE IS CAB2; IT IS NOT AB12**. This homework relates to hash functions for block ciphers (sec 11.3.2) Block size = 8 bits. Hash size = 8 bits. Encryption function: Divide the key into two halves: LK and RK; Divide the plaintext into two. halves: LT and RT; Then ciphertext= LC RC where LC=LK XOR RT; and RC = RK XOR LT ...
