| 摘 要： | 针对车载自组网中存在的安全隐患,提出一种身份认证机制.将门限RSA签名技术应用到车载自组网中,从而保证了车载自组网中节点通信信息的保密性、真实性、完整性及不可否认性.实验结果表明,在成员数量和门限值不断变换下,分发时间和合成时间变换比较稳定,说明此模型是稳定性较好的模型,所以将门限RSA签名技术应用于保证车载自组网节点通信的信息安全性是正确可行的.

| Abstract: | Aiming at the security problems which exist in the vehicle ad hoc networks, the paper proposes a new distributed authentication scheme.The threshold RSA signature technology is used in VANETs to realize the data privacy,authenticity,integrality and nonrepudiation. The conclusion is drawn that this is a stable scheme because the change of the distribution of time and the composition of time is stable,and this is a appropriate and feasible scheme which use the threshold RSA signature technology to realize the safety of information in VANETs. |
