An Efficient Abuse-Free Fair Contract-Signing Protocol Based on RSA Signature and Σ-protocol
Xi-Jun Lin and Lin Sun
Abstract
A fair contract-signing protocol is an important mechanism which allows two participants to sign a digital contract via the public computer networks in a fair way. Based on the RSA signature scheme and Σ-protocol, we propose a new contract-signing protocol in this paper. The proposed protocol is not only fair and optimistic, but also efficient and abuse-free. Moreover, security and efficiency analysis are provided.
