A NEW SECURED VoIP USING VERIFIABLE SECRET SHARING

Voice communication carried out using the Internet Protocol (IP) for the transaction is known as Voice over Internet Protocol (VoIP). Voice over Internet Protocol is a technology for communicating using “Internet protocol” instead of traditional analog systems. Some VoIP services need only a regular phone connection, while others allows making telephone calls using an Internet connection instead. Some VoIP services may allows only to call other people using the same service, but others may allow to call any telephone number including local, long distance, wireless and international numbers. The fundamental idea of secret sharing is the secret message is sending through a single specified path in secured manner, so secrete sharing is must for sharing VoIP messages. There are several secret sharing’s used in VoIP, the most secured VoIP is Verifiable Secret Sharing (VSS). Verifiable Secret Sharing is an important primitive in distributed information that allows a dealer to share a secret among huge number of parties. Verifiable secret sharing is a way of giving information to a set of processors such that a quorum of processors is needed to access the information. VSS is a fundamental tool and distributed computing. Experimental result shows thus the proposed method of verifiable secret sharing is much secured because it overcomes the problems from packet loss, delay, security and quality.
