Biometric authentication establishes the identity of an individual based on biometric templates (i.e. fingerprints, retina scans etc.). Although biometric authentication has important advantages and many applications, it also raises serious security and privacy concerns. In this parer, we investigate a privacy-preserving biometric authentication protocol that has been proposed by Bringer et al....

The anticipated increase in mobility and popular use of the mobile services will require more technologies for authenticating mobile hosts and protecting their privacy. However, the issues such as privacy and confidentiality in mobile computing environments and the resource restriction of mobile hosts have not been given enough consideration. In this paper, we present an authentication protocol...

In the research literature, a typical authenticated key agreement protocol is designed to realize mutual authentication and key secrecy. In a network, as a crucial cryptographic primitive, key agreement can establish secure communication channels for communication entities. Meanwhile, the users privacy is particularity important, especially for multi-server authentication environment. Network p...

The Secured communication protocol via encrypted key ensuring message integrity combination of Authentication of Third Party Authentication Quantum Key Distribute Protocol (implicit) and Third Party Authentication Quantum Key Distribute Protocol Mutual Authentication (explicit) quantum cryptography is used to provide authenticated secure communication between sender and Receiver. In quantum cry...

Recently, Aydos et al. proposed an ECC-based wireless authentication protocol. Because their protocol is based on ECC, the protocol has significant advantage including lower computational burden, lower communication bandwidth and storage requirements. However, Mangipudi et al showed that the protocol is vulnerable to the man-inthe-middle attack from the attacker within the system and proposed a...

In this paper, we introduce an efficient anonymous authentication protocol in Vehicular Ad-hoc Networks (VANETs) [5] to resolve the issue on anonymous authentication for communication between roadside units and vehicles. Our proposed protocol cannot only guarantee privacy, anonymity, and other basic cryptographic requirements but also provide traceability of illegal users. Our proposed protocol...
