A Selectable k-Times Relaxed Anonymous Authentication Scheme

An Anonymous Authentication Scheme for Trusted Computing Platform

The Trusted Computing Platform is the industrial initiative to implement computer security. However, privacy protection is a critical problem that must be solved in Trusted Computing Platform. In this paper, we propose a simple and efficient method to implement anonymous authentication in such setting. The new scheme is proved to be secure under the strong RSA assumption and decisional Diffie-H...

An improved anonymous authentication scheme for roaming in ubiquitous networks

With the evolution of communication technology and the exponential increase of mobile devices, the ubiquitous networking allows people to use our data and computing resources anytime and everywhere. However, numerous security concerns and complicated requirements arise as these ubiquitous networks are deployed throughout people's lives. To meet the challenge, the user authentication schemes in ...

An efficient and secure anonymous mobility network authentication scheme

The demands of Internet users are steadily increasing. Many users access Internet services through mobile devices via wireless networks. To prevent disclosure of private data, researchers have proposed various anonymous roaming authentication schemes which apply different technologies to provide integral security properties, such as symmetric and asymmetric encryption, digital signature, timest...

An 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...
