Mutual Authentication and Key Exchange Protocols with Anonymity Property for Roaming Services
نویسندگان
چکیده
Two novel mutual authentication and key exchange protocols with anonymity are proposed for different roaming scenarios in the global mobility network (GLOMONET). The proposed protocols have new features, such as identity anonymity and one-time session key progression. Identity anonymity protects mobile users’ privacy in the roaming network environment. One-time session key progression frequently renews the session key for mobile users and reduces the risk of using a compromised session key to communicate with visited networks. It is shown that the computation complexity of the proposed protocols is similar to the existing one appeared in the literature, while the security has been significantly enhanced.

متن کاملAn Improved Anonymous Authentication Scheme for Roaming Services
In wireless network and mobile network, a two-factor authentication scheme for roaming services enables a mobile user to achieve mutual authentication and key agreement with the foreign agent. In this paper, we review Kim et al.’s anonymous authentication scheme in global mobility networks. Analysis shows that Kim et al.’s scheme fails to achieve anonymity and two-factor authentication. In addi...

An anonymous authentication scheme for roaming services in global mobility networks allows a mobile user visiting a foreign network to achieve mutual authentication and session key establishment with the foreign-network operator in an anonymous manner. In this work, we revisit He et al.'s anonymous authentication scheme for roaming services and present previously unpublished security weaknesses...
متن کاملAnonymity and one-way authentication in key exchange protocols
Key establishment is a crucial cryptographic primitive for building secure communication channels between two parties in a network. It has been studied extensively in theory and widely deployed in practice. In the research literature a typical protocol in the public-key setting aims for key secrecy and mutual authentication. However, there are many important practical scenarios where mutual aut...
