WebThe concept of forkcipher, a new kind of cryptographic primitive, has been proposed as a mean to sidestep the overcome the limitations of AE schemes based on typical primitives (such as blockciphers). This paper introduces a forkcipher construction that is based on the tweakable blockcipher KIASU, which WebA forkcipher is a keyed, tweakable function mapping an n-bit input to a 2nbit output, which is equivalent to concatenating two outputs from two permutations. A forkcipher can be a useful primitive to design authenticated encryption schemes for short messages.
