Provably Secure Multi-Server Authentication Protocol Using Fuzzy Commitment

Cryptanalysis of Design and Analysis of a Provably Secure Multi-server Authentication Scheme

The rapid growth of inter-networking and communication technologies resulted in an exponential hit rate on commercial service providing websites (servers) like Google, Amazon, Flipkart etc. from remote users connected via Internet. To handle the networking load, the organizations are moving from the traditional two tier client server architecture to multi-server architecture for efficient load ...

Provably-Secure Enhancement on 3GPP Authentication and Key Agreement Protocol

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

A novel multi-server authentication protocol

Recently, Tsai and Hsiang et al. each proposed a multi-server authentication protocol. They claimed their protocols are secure and can withstand various attacks. However, after our analysis, we found some security loopholes in each protocol. We will first show the attacks on their schemes and then present ours. After the security analysis, we conclude that our scheme is the most secure one amon...

Provably Secured Two Server Hash Password Authentication

The techniques of secured socket layer (SSL) with client-side certificates for commercial web sites rely on a relatively weak form of password authentication. Browser sends a user’s plaintext password to a remote web server using SSL is vulnerable to attack. In common password attacks, hackers exploit the fact that web users often use the same password at many different sites. This has drawn at...
