Personal Authentication Protocol based on ECDLP using Biometric Feature Values


Jayaprakash Kar, Bansidhar Majhi


Vol. 9  No. 6  pp. 79-84


This paper proposes a new Biological personal authenti?cation protocol which helps to establish trust by identify?ing a particular user or system. It is a one-way authenti?cation protocol. Here the biological information, what?ever its kind such as fingerprints, iris, retina DNA, tis?sue 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. Our Protocol is based on Elliptic Curve Discrete Logarithm Problem (ECDLP). Here the entity is gener?ating two numbers for his 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.
