摘要:

为了均衡车辆编队跨信任域身份认证的安全和效率,提出了区块链架构下具有条件隐私的车辆编队跨信任域高效群组认证方案。设计了面向车辆编队身份认证的新型区块结构BM-Tree,通过多信任域间链上认证参数共享为跨信任域群组认证提供支撑;采用动态匿名进行车辆身份隐私保护,通过双线性映射进行信任域参数变换,实现了具有条件隐私的跨信任域群组认证;提出了基于 BM-Tree 的高效群组认证协议,实现了车辆编队批量身份认证和重认证。所提方案在安全性和计算开销方面明显优于现有跨信任域认证方法,相比BLA、MDPA和BBA,整体认证时延平均减少了29%、25%和53%。

Abstract:

In order to balance the security and efficiency of vehicle platoon cross trust-domain identity authentication, an efficient cross trust-domain group authentication scheme with conditional privacy of vehicle platoon under blockchian architecture was proposed.A novel block structure BM-Tree was designed for vehicle platoon identity authentication, which provided support for efficient cross trust-domain group authentication by sharing the group authentication parame-ters on the blockchain.Dynamic pseudonym was used for vehicle identity privacy-preserving and bilinear mapping was used to transform the trust-domain parameters, which realized cross trust-domain group authentication with conditional privacy.An efficient group authentication protocol based on BM-Tree was proposed, which realized batch identity au-thentication and re-authentication of vehicle platoon.The proposed scheme has better performance than existing cross trust-domain authentication methods in terms of security and computational overhead.Experimental result shows that the authentication delay is reduced by 29%, 25% and 53% on average, respectively compared with BLA, MDPA and BBA.

Key words: vehicle platoon, cross trust-domain, blockchain, privacy-preserving, group authentication
