Cryptographic Analysis of DES and RSA Algorithm Using the AVISPA Tool and WSN

With the world-changing toward IoT, wireless sensors networks (WSN) are becoming more important than ever. WSN is a complex distributed system accustomed to several technological fields especially in the area of security. Wireless sensor network deals with several research issues concerning security and energy efficiency. WSN uses cryptography as a method to ensure network data security and authentication. This paper reconsiders the algorithms of cryptography and improves them by eliminating any flaws in it, using the AVISPA tool. In this paper, symmetric and asymmetric key cryptographic algorithms like DES, RSA and the improved RSA were compared using the AVISPA tool. The objective is to enhance the existing algorithms in order to remove the flaws and to provide a more secure algorithm. To augment the security, we used two sessions as compared to one in the case of existing algorithms. To conclude, the improved algorithm is more secured as compared to existing algorithms.
