GENERATE A KEY FOR AES USING BIOMETRIC FOR VOIP NETWORK SECURITY



VoIP technology in general refers to the set of software, hardware and industry standards that enable “voice” to be transported using the Internet Protocol (IP). The technology is compelling to a wide audience for several reasons: • VoIP phone bills are typically cheaper than traditional phone bills to the consumer. • VoIP networks offers providers easier IT management and reduction in operating cost for a combined network for voice and data. • VoIP technology is feature rich to support next generation multimedia applications With private phone conversations being conducted on insecure public networks, security of VoIP communications is increasingly important. VoIP has a very different architecture than traditional circuit based telephony, and these differences result in significant security issues. Encryption is one of the essential security technologies for computer data, and it will go a long way toward securing VOIP[1,2,3]. In our discussion we proposed a Biometric-Crypto system which generates a cryptographic key from the fingerprints for Encrypting and Decrypting the voice data packets for VoIP Security. if your VoIP packets traverse the Internet to reach a destination, a number of attackers have a shot at your voice data. The calls are also vulnerable to hijacking or a man in the middle attack . In such a scenario, an attacker would intercept a connection and modify call parameters. This is an especially scary attack, since the participants likely wouldn’t notice a change. The ramifications include spoofing or identity theft and call redirection, making On Five Definitions of Data Integrity .

In our approach we have proposed a system which will encrypt the VoIP data packets using Advanced Encryption Standard (AES)[7] with the novel method of Biometrics based Key Generation technique.

Voice over Internet Protocol (VoIP) [1] is a protocol optimized for the transmission of voice through the Internet or other packet switched networks. VoIP is often used abstractly to refer to the actual transmission of voice . VoIP is also known as IP Telephony[2,4], Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband. “VoIP” is pronounced voyp. VoIP calls can take place between LAN or on WANs, as is the case with internal calls on a corporate network. If a VoIP user wishes to call a destination on POTS, a special gateway is used. These devices act as connectors between the data network and the SS7 network used by POTS. They translate the incoming data into a format the recipient, be it IP or SS7, can understand. In the process of saving money and increasing efficiency, two crucial portions of any infrastructure, voice and data, were combined.
