A Proposal for a Biometric Key Dependent Cryptosystem
K. Hassanain, Mohamed Shaarawy, El Gamal Hesham · Global Journal of Computer Science and Technology · 2010
With the increasing reliance on electronic information, which needs to be exchanged across the internet or stored on open networks, cryptography is becoming an increasingly important feature of computer security. A biometric key dependent cryptosystem is proposed, to ensure the security of the whole system by using fingerprint features as a key in a cryptosystem, like, key-dependent Advanced Encryption Standard (KAES). KAES is used to ensure that no trapdoor is present in cipher and to expand the key-space to slow down attacks.
