Abstract
The transmission of the encryption voice over IP is challenging. The voice is recorded, eavesdropping, change and theft voice, etc. The voice over IP is encrypted by using Advance Encryption Standard (AES) Algorithm. AES key is generated from Minutiae Points in fingerprint. By other way, we talk about biometric-cryptosystem, which is hybrid between one of the cryptosystems and biometric systems, such as fingerprint using for authentication as well as to generate cryptographic key to encrypt voice over IP by applying AES. In this paper, we define a new term which is Fingerprint Distribution Problem (FDP) based on Key Distribution Problem. Also, we suggest a solution for this problem by encrypted fingerprint before sending between users by using one of the public key cryptosystems which is RSA Algorithm.
