—Wireless Sensor Networking is one of the most promising technologies that have applications ranging from health care to tactical military. Although Wireless Sensor Networks (WSNs) have appealing features (e.g., low installation cost, unattended network operation), due to the lack of a physical line of defense (i.e., there are no gateways or switches to(More)
A highly efficient Binary PSO based cryptanalysis approach for four-rounded DES is presented. Several optimum keys are generated in different runs of the algorithm on the basis of their fitness value and finally, the real key is found by guessing every individual bit. The robustness of the proposed technique is also checked for eight-rounded DES. Our(More)
In recent years, Body Area Networks (BANs) have gained immense popularity in the domain of healthcare as well as monitoring of soldiers in the battlefield. Security of a BAN is inevitable as we secure the lives of soldiers and patients. In this paper, we propose a security framework using Keyed-Hashing Message Authentication Code (HMAC-MD5) to protect the(More)
Cryptanalysis of feistel ciphers is difficult due to their high nonlinearity and autocorrelation. On the other hand, substitution ciphers are easily breakable due to their simpler encryption process. In this paper, a highly efficient Binary Particle Swarm Optimization (PSO) based cryptanalysis approach for four-rounded Data Encryption Standard (DES) is(More)
