面向车云网量子加密通信架构的轻量化身份认证方案研究

Research on Lightweight Authentication Scheme for Quantum Encrypted Communication Architecture in Vehicular Cloud Networks

为解决车联网技术中身份认证问题,在车云网量子通信架构的基础上,设计了一种轻量化身份认证方案,认证过程由注册和认证2个阶段构成,车辆与车联网云平台间进行2轮认证以确保方案的安全性。试验结果表明,该方案计算开销仅为0.179 ms,通信开销为417 B,与其他4种相关方案相比,具有更低的计算开销和通信开销,在兼顾安全性的同时具备更高的效率,对于大多数低计算量和低通信量的车联网设备具有更高的适用性。

In this research,a lightweight authentication scheme was designed based on the quantum communication architecture of the Internet of Vehicle(IoV)cloud network.The authentication process consists of 2 stages:registration and authentication,and 2 rounds of authentication between the vehicle and the IoV cloud platform to ensure the security of the scheme.Test results show that this scheme has computational overhead of only 0.179 ms,and communication overhead of 417 B,which is lower than other 4 schemes,had has high efficiency while ensuring security,therefore it has high applicability for most IoV equipment with low computational amount and low communication volume.
