基于区块链的战场车辆假名更换策略研究OA北大核心CSTPCD

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.
