“车辆到电网”（V2G）电力将是一种新的绿色能源方案，其中电动或插电式混合动力车辆与智能电网通信，通过将电力输送到电网或通过限制其充电速率来销售需求响应服务。由于车辆速度快、连接分散、通信范围有限、需要传输的数据量大，V2G通信对快速认证和加解密有着至关重要的要求。针对车载通信的特点，提出了一种独特的批量认证协议UBAPV2G。性能分析表明，UBAPV2G具有认证时延小、计算量小、通信量少等优点，安全性分析表明，UBAPV2G具有较强的安全防御能力。实验结果还表明，UBAPV2G可以实现更少的认证延迟，大量的数据包。因此，UBAPV 2 G协议适合于真实的实时V2 G通信的严格要求。
“Vehicle-to-grid” (V2G) power will be a new green energy scheme in which electric or plug-in hybrid vehicles communicate with the smart grid to sell demand response services by either delivering electricity into the grid or by throttling their charging rate. Due to high vehicular speed, sporadic connection, limited communication range, and large volume of data that need to be transmitted, V2G communications have the crucial requirements of fast authentication and encryption/decryption. This paper proposes a unique batch authentication protocol UBAPV2G that takes into account the characteristics of vehicle communication. The performance analysis shows that UBAPV2G can achieve less authentication delay, less computational cost, and less communication traffic, and security analysis shows that UBAPV2G is strong enough to defend against security attacks. The experimental results also demonstrate that UBAPV2G can achieve less authentication delay for large number of packets. Thus, UBAPV2G protocol is suitable for the stringent requirement of real time V2G communications.
