基于区块链的群机器人数据完整性与隐私性保护

Blockchain-based Data Integrity and Privacy Protection for Swarm Robotics

群机器人通过多个机器人之间的信息交互实现协同控制,保证交互数据的私密性和不可篡改是群机器人系统安全可靠运行的关键。针对群机器人系统中存在的恶意数据篡改、重要信息泄露等潜在安全问题,提出了一种基于区块链技术的群机器人数据完整性与隐私性保护方案。首先,该方案利用去中心化的分布式账本保障群机器人系统数据的完整性,并针对区块链数据公开的特性,引入脱链加解密模块避免明文数据上链,提高了数据的隐私性。其次,考虑到区块链的运行条件和物理机器人在存储和计算能力方面的性能约束,提出采用轻节点方法来降低在物理机器人上运行区块链的存储和计算负担。最后,通过实验对方法进行了验证。结果表明,基于区块链技术的保护方法对群机器人数据完整性和隐私性具有较好的保护效果,且轻节点方法可实现区块链在机器人集群上的部署。

Swarm robotics realizes collaboration and control through information interaction between robots,ensuring the privacy and non-tampering of interactive data is the key to the safe and reliable operation of swarm robotic systems.To solve the potential security problems of malicious data tampering and significant information leakage in swarm robotic systems,data integrity,and privacy protection method for swarm robotics based on blockchain technology is proposed in this paper.Firstly,Decentralized distributed ledgers are used in this solution to ensure the data integrity of the swarm robotic systems.And aiming at the characteristics of the blockchain data disclosure,the off-chain encryption and off-chain decryption module are introduced to avoid uploading plaintext data to improve data privacy.Secondly,considering the operating conditions of blockchain and the performance constraints of physical robots in terms of the storage and computing power,a light node approach is proposed to reduce the storage and computing burden of running blockchain on the physical robot.Finally,the method proposed is verified by experiments.The results show that the protection method based on blockchain has a better protective effect on the data integrity and privacy of swarm robotics.The light node method can realize the deployment of blockchain on swarm robotics.
