Implementation and integration of efficient ECDH key exchanging mechanism in software based VoIP network

ECC based key management is used to further strengthen the symmetric block cipher. This mechanism proposes the faster computation of the algorithm with smaller key size. High level security of ECDH based security has the difficulty of discrete logarithm problem for breaking the keys. In this paper, implementation of ECDH key exchanging mechanism in real time using the open source PBX software Asterisk and IP phone has been carried out.
