A new approach for secret sharing of key in networks is proposed in this paper. Secret key sharing is an important problem in cryptography. This paper explains how secret key can be safely transmitted by combining Classical cryptography and Quantum techniques. The usage of dual channel technique and programmable polarizer are analyzed which ensure the way to remove the practical difficulties of quantum cryptography. This hybrid combination result in feasibility of authentication and hacker identification there by introducing a novel method for secret key transmission.
