摘要:

车载自组网( VANET)中频繁的通信和海量数据交互更易泄露车辆身份、位置、行驶路线等信息,交互验证的过程中证书开销会越来越大而且更容易遭受恶意攻击。 为了

解决以上问题,提出了基于区块链的 VANET 无证书聚合签名方案,消除证书开销,使用假名保护用户身份隐私。 使用椭圆曲线加密算法实现无证书聚合签名,结合区块链的分布式存储实现信息共享、道路信息透明以及对恶意参与者的追踪。 搭建以太坊私有链进行仿真,利用智能合约实现访问控制和交易,实验结果表明,在实现强匿名性、不可链接性、消息完整性、不可否认、可追踪、防篡改的安全性能的同时,通信开销相比同类方案中使用双线性配对方法降低了至少 85. 8% 。

Abstract:

Frequent communication and massive data interaction in the vehicular ad hoc network ( VANET) are more likely to disclosevehicle identity,location,driving route?

and other information. In the process of interactive verification,the certificate overhead will belarger,and it will be more vulnerable to malicious attacks. To solve?

these problems,a certificateless aggregate signature ( CLAS) schemefor VANET based on blockchain is proposed, which eliminates certificate overhead and uses pseudonyms to protect users ’ identityprivacy. CLAS is realized by using the elliptic curve cryptography ( ECC ) algorithm, and information sharing, road information　transparency and tracking of malicious participants are realized by combining the distributed storage of the blockchain. It builds theEthereum private chain for simulation and uses the smart contract to achieve access control and transaction. The experimental results showthe communication cost is reduced by at least?

85. 8% compared with the bilinear pairing method in the same scheme,while realizing thesecurity performance of strong anonymity,unlinkability,message integrity,

nondenial,traceable and tamper-proof.
