A Secure Communication for Wireless Sensor Networks: Through Hybrid (Aes +ecc) Algorithm Padmashali

"A SECURE COMMUNICATION FOR WIRELESS SENSOR NETWORKS THROUGH HYBRID (AES +ECC) ALGORITHM" A group of sensor nodes deployed in a particular environment constitutes a wireless sensor network (WSN). At times the wireless sensor network can be even deployed in a very sensitive area where the security becomes a great problem. The present asymmetric encryption methods and the symmetric encryption methods can offer the security levels but with many limitations. For instance key maintenance is a great problem faced in symmetric encryption methods and less security level is a problem of asymmetric encryption methods even though key maintenance is easy. However a hybrid encryption method that combines both symmetric and asymmetric key can provide high security with minimized key maintenance. This book takes the reader to understand how a hybrid encryption method where elliptical curve cryptography (ECC) and advanced encryption standards (AES) are combined to provide node authentication and secure key exchange in wireless sensor network (WSN).
