A Unified Security Perspective on Legally Fair Contract Signing Protocols

Diana Maimut and George Teseleanu

Abstract: Inspired by Maurer's universal zero knowledge (UZK) abstract perspective and building on legally fair contract signing protocols without keystones, we propose and analyze the security of the first UZK class of co-signing protocols. We construct our main idea considering the stringent issue of scheme compatibility which characterizes communication systems. Typical examples are the cases of certificates in a public key infrastructure and the general issue of upgrading the version of a system. Thus, working in a general framework may reduce implementation errors and save application development and maintenance time.
