摘要/Abstract

摘要：

针对车辆社交网络建立车队中存在的安全性和隐私性威胁进而阻碍车队技术发展的问题,提出一种结合区块链和车辆社交网络的自动驾驶车队成员推荐方案。首先,提出一系列安全协议来构成隐私保护的车队推荐算法;其次,融合同态加密和安全多方计算来保护数据安全,并降低隐私泄露的风险;最后,结合区块链和车辆社交网络以实现系统的高效运行。安全性证明表明该方案满足隐私保护的要求。此外,实验结果显示,所提出方案的通信成本和计算成本都是可接受的,而且对于车队的组建是可靠有效的。

关键词: 车辆通信, 区块链, 隐私保护, 同态加密

Abstract:

Aiming at the problems of safety and privacy threats in establishing autonomous vehicle platoons in vehicle social networks, which would hinder the widespread adoption of platoons, a scheme for recommendation of autonomous vehicle platoon members by combining the blockchain and vehicle social networks is proposed. A series of security protocols to form a privacy platoon recommendation algorithm is first proposed. Second, the homomorphic encryption and secure multi-party computing are integrated to protect data security and reduce the risk of privacy leakage. Finally, the blockchain and vehicle social networks are combined to achieve efficient system operation. The proof of security shows that the proposed scheme meets the requirement of privacy protection. Besides, experimental results show that the cost of communication and that of calculation in the proposed scheme are both acceptable and reliable and effective for the formation of the platoon.

Key words: vehicular communication, blockchain, privacy protection, homomorphic encryption
