Abstract

Abstract : Security in the wireless networks is the main factor when they are deployed in a harsh environment, and this is the crucial factor in the case of sensor networks. Cryptography has a significant role to achieve this in wireless sensor networks. Though there exist several cryptographic algorithms, but none of them provide desired results for security. In this paper, a new cryptographic technique has been developed that uses both symmetric and asymmetric methods. In the proposed algorithm, advanced encryption standard (AES), data encryption standard (DES), and modified Rivest–Shamir–Adleman (m-RSA) are used in different phases of the algorithm because symmetric techniques provide a high level of security and asymmetric ones provide easier key management. In phase 1 of an algorithm, AES has been used; in phase 2, DES has been used; and in the last phase, m-RSA has been used, and all three phases are executed in parallel. The proposed algorithm is compared with existing techniques in terms of total execution time and decryption time, and it has been analyzed that the proposed algorithm provides a better result as compared to the existing algorithm.
