Achieving a beyond the birthday bound security would provide a larger data limit for a single key. 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.
