基于群签名的远程测量系统安全协议

在我们设计的远程测量系统中，多个基于ARM 的嵌入式系统位于测量点，管理员可
通过网络对其进行访问。为实现系统的安全访问，设计了基于群签名的远程测量系统访问协议。本协议采用可验证的、无可信中心的(k, n)门限密码系统产生系统的公/私密钥，征集k个管理者为系统中的用户生成证书和访问测量系统的公/私密钥。分析显示协议能极好的抵御各种攻击。

Abstract: In our long-range measurement system, ARM-based embedded devices located in the measurement points. Managers can access the devices through internet. The Group-Signature-based Secure Protocol for long-range measurement system was designed for security. In our protocol, a verifiable threshold cryptosystem without a trusted center is applied to generate system public/private keys. K managers can generate certification and user public/private keys for user. The security analysis show that the protocol has desirable features of reliability, accountability and is secure in the presence of a variety of possible attacks.
