Secure Identity-Based Key Establishment Protocol

Diffie-Hellman key exchange protocol is a well known protocol for establishing the key on the open channel but due to man-in-middle attack confidentiality of the message might be compromised. Public Key Infrastructure (PKI) requires a central authority or trusted third party to provide fundamental security services. To address above issues like trustiness in PKI and man-in-middle attack in Diffie-Hellman, we propose a secure identity-based key management scheme which combines the principles of Diffie-Hellman, third party and uses the identity of the receiver to establish the common key between two nodes.
