SECURED AND EFFICIENT PIN ENTRY METHOD USING ECC

Abstract

Security of one-time password (OTP) is important because now a days most of the e-commerce transactions are achieved with the help of this device. OTP is used to counter Replay attack/overhearing. Replay attack or overhearing is type of attacks happening network-connected computing environment or isolated computing environment. Alternative problem with most of the current implementation of security models is storing of top-secret keys. Cryptographic keys are regularly kept in un–secured way that can either be solved/social-engineered or obtained through brute force attacks. This becomes a poor link and leads integrity issues of sensitive data in a security model. To overcome the above problem, biometrics is united with cryptography for developing solid security model. This paper suggests enhanced security model of OTP method via ECC using palm vein biometric. This model also suggests better security with lesser key size than additional prevalent public key cryptographic model .The cryptographic keys are not required to remember or keep anywhere, these keys are generated as and when wanted.
