Provable analysis and improvement of smart card–based anonymous authentication protocols

Nowadays, authentication protocols are essential for secure communications specially for roaming networks, distributed computer networks, and remote wireless communication. The numerous users in these networks rise vulnerabilities. Thus, privacy‐preserving methods have to be run to provide more reliable services and sustain privacy. Anonymous authentication is a method to remotely authenticate users with no revelation about their identity. In this paper, we analyze 2 smart card–based protocols that the user's identity is anonymous. However, we represent that they are vulnerable to privileged insider attack. It means that the servers can compromise the users' identity for breaking their privacy. Also, we highlight that the Wen et al protocol has flaws in both stolen smart card and stolen server attacks and the Odelu et al protocol is traceable. Then, we propose 2 modified anonymous authentication protocols. Finally, we analyze our improved protocols with both heuristic and formal methods.

Anonymous Shared Certificate Entity Authentication Protocol

Currently most existing entity authentication protocols can not guarantee anonymity against compromised verifier in semi-honest model. To solve the question, this paper puts forward a shared certificate entity authentication model, by which some qualities for anonymous entity authentication in semi-honest situation are suggested reasonably. On basis of our proposed model, this paper designs two anonymous entity authentication protocols including an anonymous shared certificate bi-entity authentication protocol and an anonymous shared certificate multi-entity authentication protocol. In proposed protocols it is only single certificate that is used to verify identity correctly and anonymously for legitimate users who has different identity secret. Any compromised verifier has capability to verify correctly whether the user identity is legitimate or not, but it is difficult for it to judge which legitimate user has been verified and distinguish who the verifying user is in particular, therefore attacker does not learn any useful information from legitimate user by spying upon the information of public channel or compromising the certificate. So the security requirements of anonymous entity authentication are achieved successfully, meanwhile the proposed model is more feasibly and effective than zero knowledge protocol in practical applications.

Conditional privacy-protection remote user authentication mechanism for WBAN

A conditional privacy-protection remote user authentication scheme based on a certificateless group signature was proposed,which can accomplish the anonymous mutual authentication between the user and the remote doctors.In addition,when the doctors perceived that users were in case of an emergency,the mechanism enabled the only group manager (GM) to expose the real identity information of users and given users timely assistance.The scheme can provide the anonymity,traceability,mutual authentication,non-reputation and some other security features.The performance analysis results show the scheme is more suitable for WBAN.
