WebWith a modern block cipher with 128-bit blocks such as AES, the birthday bound corresponds to 256 EB. However, for a block cipher with 64-bit blocks, the birthday bound corresponds to only 32 GB, which is easily reached in practice. When the amount of data encrypted under a fixed key approaches this limit, the security guarantees of the mode of ... WebIf one of the CTR mode cipher texts is 16 GB, you will have revealed the entire code book, and the adversary will not need the key. If you have a hard time seeing this, consider a 2-bit block cipher in CTR mode that has produced the ciphertext stream 3-1-0. If Eve has tricked us into encrypting 0 three times, then the next CTR value must be 2 ...
