Two-factor-based RSA key generation from fingerprint biometrics and password for secure communication

Abstract In an asymmetric-key cryptosystem, the secure storage of private keys is a challenging task. This paper proposes novel approach for generating same public and key pair on need basis. Hence, done away with. The proposed based two factors: fingerprint biometrics password. A stable binary string generated from distances among pairs minutiae points in using gray code-based method. Experiments show that code representation significantly reduces number inconsistencies between bit strings instances as against representation. Reed–Solomon error correction successfully corrects errors due to variations multiple induce stability string. Hash hashed password are XORed derive seed value. uses this value generate large prime numbers. These numbers used RSA generation ensures every time. experimental results can ensure key.
