In the WSN security mechanisms, authentication and encryption is the most important module. However, sensor nodes with limited computing resources and storage resources, making the deployment of security mechanisms in the nodes need to consider their storage space, power consumption and other factors. If using hardware cryptographic module will increase the cost of the node, limiting large-scale applications. In order to reduce sensor node energy consumption, cost, space requirements, this paper have been studied and improved advanced encryption standard algorithms, and presented a lightweight high-level encryption algorithm.
