摘　　要：针对当下基于区块链的车载自组网身份认证协议存在的隐私保护差、存储负载重与认证时延高等问题,提出一种基于区块链的新安全认证协议。该协议引入了动态累加器,为车辆提供隐私性保障的同时,将存储开销降低至常数级。结合预计算的设计模式,克服认证时延高的挑战。实验表明,本方案可以满足车辆用户的各项需求,具有良好的可落地性。Such problems as poor privacy protection,heavy storage load and high authentication delay,etc.exist in the identity authentication protocol based on the block chain.A new safety authentication protocol based on block chain is proposed.The dynamic accumulators are introduced into the protocol,while the privacy support of vehicles are provided,the storage overhead is decreased to constant level.The design mode of pre-calculation is combined to overcome the challenges of high delay of authentication.The experiment shows that the scheme can meet with each item of requirement of the vehicle operator and has super execution.
