Oblivious transfer protocols over braid groups
辫群上的不经意传输协议

The rapid development of quantum computing brings great challenge to cryptographic protocols based on the integer factorization or the discrete logarithm problem. In order to research quantum cryptanalysis-resistant cryptographic protocols, this paper proposed a 1-out-of-2 oblivious transfer protocol based on non-commutative braid group, which was extended to a 1-out-of-N oblivious transfer protocol. The protocols could provide privacy for both the sender and the receiver on base of the difficulty of the conjugacy search problem and the multiple conjugacy search problem.
