Some guidelines for non-repudiation protocols

Abstract

Non-repudiation protocols aim at preventing parties in a communication from falsely denying having taken part in that communication; for example, a non-repudiation protocol for digital certified mail should ensure that neither the sender can deny sending the message, nor the receiver can deny receiving it. We identify some guidelines for non-repudiation protocols. The guidelines are derived by examining a series of non-repudiation protocols that descend from a single ancestor.
