Abstract– Wireless Sensor Networks (WSN) introduce a new way to interact with the physical environment. The security in WSNs became an attractive area of research. WSNs are susceptible to a wide range of malicious attacks. At present ECC is considered for secure communications, which is having good potential for WSN security due to its smaller key size and its high strength of security. Unfortunately, the execution time of ECC is more which is not suitable for more number of applications. A number of other security mechanisms have been proposed for sensor networks to provide data confidentiality, namely Advanced Encryption Standard (AES) and Data Encryption Standard (DES). In this paper, we propose an algorithm, which is compared and analyzed with the existing ECC and AES to provide better security with authenticated sensor nodes. The authentication is done with a secret code. The proposed algorithm will ensure the secure communication with authenticated devices. The analysis results shows that the scheme works better than the common existent schemes with better utilization of available memory.
