Протокол для сохранения конфиденциальности профиля в социальных сетях

Abstract

One of the central problems in the development of distributed systems is the design of cryptographic protocols that meet specified functional requirements and preserve user privacy. Methods of conventional encryption algorithms typically use PKI. In this paper we presented a method based on other approach. The authors have developed a cryptographic framework for access control, ensured the confidentiality of social relations, secrecy of resources and anonymity of users in social networks. The implementation of the protocols in the framework is combination of zero-knowledge proof and signature schemes Camenisch-Lysyanskaya.
