Abstract:

Signcryption is a cryptographic method that fulfills both the functions of secure encryption and digital signature with less cost. To transmit secure and authenticated message in wireless sensor networks, an efficient signcryption scheme with forward secrecy based on elliptic curve, which was presented by HWANG, was modified and it was implemented in TinyOS, which is called TinySignCrypt. Compared with other schemes, the experimental results in the MICA2 platform show TinySignCrypt has better performance in terms of communication and computation load.

摘要：

签密是一种以很小开销同时完成安全加密与数字签名的密码学方案。为了在无线传感器网络中实现安全可认证的信息传送， 对Hwang提出的基于椭圆曲线的具有前向性安全的高效签密方案进行修改后并在TinyOS中实现了此方案，称之为TinySignCrypt。与其他方案相比，在MICA2平台上的实验结果表明TinySignCrypt在通信量、计算量方面有更好的性能。
