A Certificateless Threshold Signature Scheme without Parings in P2P Networks

摘要：

In P2P networks, a valid signature scheme plays an important role in identification of users, authenticity and integrity of sharing information. In this paper, we propose an efficient and secure threshold signature scheme without parings and a trusted party based on CL-PKC, which fits the characteristics of P2P networks. By introducing threshold secret sharing, our scheme without a trusted party solves the risks of single-point failure caused by almost signature schemes. Moreover, our scheme is more computationally efficient than other schemes built from pairings. So the new scheme is of great practical and efficiency for P2P networks.
