WebClaw-free permutation. In the mathematical and computer science field of cryptography, a group of three numbers ( x, y, z) is said to be a claw of two permutations f0 and f1 if. f0 ( x) = f1 ( y) = z. A pair of permutations f0 and f1 are said to be claw-free if there is no efficient algorithm for computing a claw. Web4.1 Using trapdoor permutations for signatures As in the case of public key encryption, there is a naive way of using trapdoor permutations to do the signing which is not secure. The idea is to use the public permutation ˇfor the public job of veri cation, and keep the private trapdoor permutation ˇ 1 for the private task of signing. knight chrysler
