WebBirthday-Bound Message Authentication Codes (BBB MACs) in the Q2 model where attackers have quantum-query access to MACs. Assum-ing the block size of the underlying (tweakable) block cipher is n bits, the security proofs show that they are secure at least up to O(22n/3) queries in the classical setting. The best classical attacks need O(23n/4 ... WebAug 2, 2024 · With a modern block cipher with 128-bit blocks such as AES, the birthday bound corresponds to 256 exabytes. However, for a block cipher with 64-bit blocks, the birthday bound corresponds to only 32 GB, which is easily reached in practice. Once a collision between two cipher blocks occurs it is possible to use the collision to extract the …

We systematically study the security of twelve Beyond-Birthday-Bound Message Authentication Codes (BBB MACs) in the Q2 model where attackers … WebThe use of a small block length is a common strategy when designing lightweight (tweakable) block ciphers (TBCs), and several 64-bit primitives have been proposed. However, when such a 64-bit primitive is used for an authenticated encryption with birthday-bound security, it has only 32-bit data complexity, which is subject to practical attacks.
