Authentication and key exchange are fundamental techniques for enabling secure communication over mobile networks. In order to reduce implementation complexity and achieve computation efficiency, design issues for efficient and secure biometrics-based remote user authentication scheme have been extensively investigated by research community in these years. Recently, two biometrics-based authentication...
Remote user authentications are an essential tool for e-commerce in Internet environment. In these systems, identity privacy is provided by concealing user's identity. In this article, we introduce the identity privacy study of this setting, and explore a secure and efficient dynamic ID-based remote user authentication protocol with untraceability. We adapt a pair of dynamic IDs to realize the user's...
Proliferation of collaboration environments brings new issues to the area of security. In this paper, we briefly describe the characteristics of security associated with collaboration environments. We also discuss and analyze several schemes in different areas of security, including access control, secure group communication, and security management. Another contribution of this paper is a proposed...
