Personal Authentication Protocol Based on ECDLP Using Biometric Feature Values

This paper proposes a new Biological personal authentication protocol which helps to establish trust by identifying a particular user or system. It is a one-way authentication protocol. Here the biological information, whatever its kind such as fingerprints, iris, retina DNA, tissue and other features which are unique to an individual are embedded into cryptographic keys which consists of both Private and Public keys in Public Key Cryptosystem. Its Protocol is based on Elliptic Curve Discrete Logarithm Problem (ECDLP). Here the entity is generating two numbers for its own private key. If one of the numbers is stolen or modified, the system security can still be guaranteed due to the computational infeasibility of solving Elliptic Curve Discrete Logarithm Problem, unless the other variable is leaked.
