Design of lightweight digital signature system in WSNs

为了确保传感器网络中传输数据的可靠性,本文设计了一个基于对称密码体制的数字签名系统。系统使用对称密码机制来提高效率,采用硬件加密设备保证共享密钥池的安全,通过使用特定的密钥生成算法解决对称密钥的分发问题。实验结果表明,系统能耗低、效率高,具有很强的实用性。

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.
