An Implementation of AES Algorithm with the Multiple Spaces Random Key Pre-Distribution Scheme on MOTE-KIT 5040

Wireless sensor networks introduce a new way for us to interact with the physical environment. Since wireless sensor networks use radio frequency as the communication medium, chances for the information retrieved by unexpected people are becoming easier and easier. In wireless sensor networks the resources are limited; it seems that AES is a good solution for this communication problem. Beside, a good key pre-distribution scheme is needed to solve the key agreement problem in wireless sensor networks. The main goal of this work is to implement an AES algorithm with the key pre-distribution scheme proposed by Du et al. on MOTE-KIT 5040 produced by crossbow technology. Under our implementation, the actual time of computing a 64-bit secret key is shorter than Du et al.´s and the performance of AES algorithm is better than the AES proposal
