基于区块链的战场车辆假名更换策略研究

Research on Pseudonym Update Strategy for Vehicles on the Battlefield Based on Block Chain

军事物联网为车辆提供信息传递平台,可提高协同作战效率,但其中信息安全性成为关键,传统匿名保护机制在长时间使用下面临攻击风险。针对上述问题,提出基于区块链的车联网数据共享框架,并结合传统方案提出假名更新策略,通过设计车辆隐私暴露危险值来动态假名更换,可抵抗窃听、篡改等攻击。实验证明,在保障信息安全前提下,进一步解决因更新条件而造成的系统开销问题。

The military internet of things provides a platform for vehicles to transfer information and can improve the efficiency of collaborative operations.However,the information security becomes the key problem,and the traditional anonymous protection mechanism faces the risk of attack under long-term operation.To solve the above problems,a data sharing framework for Internet of vehicles based on block⁃chain is proposed,and proposes a pseudonym update strategy combined with traditional schemes is given.the vehicle privacy threat value to dynamically change pseudonyms is designed,which can resist eaves⁃dropping,tampering and other attacks.The experiments show that this scheme can further solve the system overhead problem caused by updating pseudonyms under the premise of ensuring information security.
