| Abstract: | In order to ensure the trusty of data transmitted in WSNs,a lightweight digital signature system is designed In the system,the performance is improved by using symmetric cryptography mechanism.Meanwhile,hardware encryption devices are adopted to guarantee the security of shared key pools and special signature key generation algorithm is utilized to generate dynamic signature key which makes the distribution of symmetric key easy.The experiment results show that the system is very practical for its feathers of efficient and low energy consumption compared with popular signature scheme. |
