【摘要】：为解决当前车联网中匿名认证的效率问题,利用椭圆曲线上的双线性对的性质,提出一种批量匿名认证方案。通过路侧单元节点(RSU)与车辆共同生成签名,有效减轻了VANET认证中心的负担进而提高认证效率,并且增加了攻击者提取密钥的难度,并在随机预言模型中给出其安全性证明。分析表明,该方案能够满足多种安全需求,计算开销明显降低,认证效率得到有效提高。因此,该方案在计算性能受限的物联网(Io T,Internet of things)环境中,有着重要的理论意义与应用价值。
[Abstract]:In order to solve the efficiency problem of anonymous authentication in vehicle networking, a batch anonymous authentication scheme is proposed by using the properties of bilinear pairs on elliptic curves. The signature is generated by the road side unit node (RSUU) and the vehicle, which can effectively reduce the burden of VANET authentication center and improve the authentication efficiency. It also makes it more difficult for the attacker to extract the key, and the security proof is given in the random prophecy model. The analysis shows that the proposed scheme can meet various security requirements, reduce computing overhead and improve the efficiency of authentication. Therefore, this scheme has important theoretical significance and application value in the Internet of things (IOT) environment with limited computing performance.
