New Version of AES-ECC Encryption System Based on FPGA in WSNs

Bing Ji, Liejun Wang and Qinghua Yang
According to the threat of the data transmission on wireless sensor networks, a technique for speeding up point multiplication, an improved AES-ECC hybrid encryption system with cross encrypted keys for secure key exchange is presented. This scheme use AES algorithm to encrypt data, use ECC algorithm to encrypt private key KAES and use SHA-1 algorithm and ECC algorithm to generate digital signature. With rapid advances in VLSI technology, a highly parallel FPGA design is used for their scheme, the computing efficiency of the algorithm is greatly improved. The AES encryption module and multl-scalar multiplication algorithm is also optimized.
