Summary:Now-a-days, secure communication is a significant characteristic that should be proficient to accommodate increasing demand of wireless communication. The fundamental principle of secure communication is the extraction of secret key and keeping this secret. In this paper, we propose innovative approach for secret key extraction and reconciliation. We exploit channel reciprocity through relative calibration and use this reciprocal channel as a secret key between two legitimate users. In this method, there is no physical sharing of key between users so that eavesdropper could not interfere the confidential communication. We also prove that this algorithm is more secure as compare to other algorithms. We use AES algorithm for reconciliation of secret key for secure communication.
