ABSTRACT

Biometric cryptosystem gives different methods in high secure applications. Cryptography is intended to ensure the secrecy and authenticity of message. Here we will consider symmetric key cryptography. For conventional encryption to work, the two parties must share a common key. Frequent key changes are desirable to limit the amount of data compromised if attacker learns the key. The strength of any cryptosystem rests with the Key Distribution Technique, a term that refers the means of delivering a key to two parties who wish to exchange data. Here KDC will generate a session key and distributes it to two parties. To distribute session key, KDC will use secret key shared between KDC and individual party. The key will be long, so it is difficult to remember providing Protection of this key is major issue. Instead of storing key we will generate the key dynamically with the help of biometrics. Here we will use Finger print to generate key, which is safe and fast.
