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.
Aiming at the potential security problems in MANET, an identity authentication mechanism is proposed, and the threshold RSA signature technique is applied to MANET to ensure the confidentiality, authenticity and completeness of node communication information in MANET And non-repudiation.Experimental results show that under the constant transformation of the number of members and the threshold, the distribution time and the synthesis time are relatively stable, indicating that the model is a good stability model, so the threshold RSA signature technology is applied to guarantee Vehicle ad hoc network node information security is correct and feasible.
