Abstract
Recent advances in information security requires randomly selected strong keys. Most of these keys are generated by software-based random number generators. However, implementing a Truly Random Number Generator (TRNG) without using a hardware-supported platform is not reliable. In this paper, a fingerprint authentication system using a hardware-based TRNG to produce a private key that encrypts the fingerprint template of a person is presented. The designed hardware can easily be mounted on a standard or embedded PC via its PCI interface to produce random number keys. Random numbers forming the private key is guaranteed to be true because it passes a two-level randomness test evaluated first on the FPGA then on the PC by applying the full NIST test suite. The whole system implements an AES-based encryption scheme to store the person’s secret stored on a smart or glossary card safely. The main contribution of the work is the use of new-generation hardware-based TRNGs to enhance the security of a fingerprint authentication system.KeywordsRandom Number GeneratorAuthentication SchemeAdvance Encryption StandardAuthentication SystemFast OscillatorThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
