Simple Secure Protocol for Wireless Sensor Networks

Security is one of the most important issues in all the fields, wireless sensor networks is not an exception to this. Security in sensor networks can be achieved by data confidentiality, authentication, freshness, and integrity. One of the main mechanisms used for this purpose is encryption and decryption but due to resource constraints of the sensor nodes these mechanism may affect their performance and increase the computational complexity of the nodes. This paper aims to provide a simple secure protocol for providing an efficient secure system with low computational complexity and efficient resource utilization in wireless sensor networks.
