Abstract
Large cryptographic-key ensures high security and robustness of asymmetric and symmetric cryptography. The conventional Fuzzy Vault Scheme (FVS) biocrypto-system is employed to shield private or secret-key using biometric features. The strength of FVS consists in its polynomial degree and chaff-points. In FVS, the system's performance is degraded with increment in the polynomial degree to make system robust against attacks. Similarly, valid chaff-point generation is also a crucial task that needs to be considered in the conventional FVS. Therefore, an efficient and more secure Modified FVS (MFVS) using Least Square Polynomial Curve Fitting (LSPC) is proposed in this paper to enhance the security of conventional FVS. Moreover, Newtons Divided Difference Interpolation (NDDI) based new chaff-points generation method is also proposed to minimize the number of required candidate points. The proposed system demonstrations average accuracy as 100%, Genuine Acceptance Rate (GAR) as 99%, False Rejection Rate (FRR) as 1%, and False Acceptance Rate (FAR) as 0%. Security of MFVS is analyzed against brute-force attack, it evident that 10-Million more combinations are required to break the generated Fuzzy Vault as compared to prior research. Consequently, proposed chaff-point generation reduces required candidate points by 13-times than existing methods |
