Voice over Internet Protocol (VoIP) is an internet protocol. VoIP is a new fancy and up growing technology to carry speech content over an internet protocol. A major change in telecommunication industry is the introduction of VoIP. This technology replaces the plain old traditional telephone system. The attraction of VoIP is the reduction of cost. The transmission of Real time voice data is not as easy as ordinary text data. The real time voice transmission faces lot of difficulties. It suffers

This paper addresses the Quality of Service (QoS) and security aspects of a VoIP by the modified secret sharing algorithm over a single path and multipath with reduced packet loss. The simulation results show that higher security and quality is achieved in terms of reduced delay and increased packet delivery ratio. The modified secret sharing algorithm is implemented in single path by AODV routing protocol and multipath by AOMDV routing protocol. This work is implemented in Network Simulator NS-2.
