Design and analysis of quantum detectable Byzantine protocol based on numerical list distribution
量子科技有望赋能区块链技术,提升区块链共识机制的安全性能.根据是否存在诚实独立的量子源设备,本文提出了两种可用于多个节点的高成功率的数字列表分发方法,并进一步提出了一种新的基于数字列表分发的量子检测拜占庭协议.4个节点的共识示例验证了提出的协议符合检测拜占庭协议的条件.最后通过分析和比较说明了提出的协议具有较好的实用性和安全性.与其他协议相比,本文提出的共识协议不仅能用于解决包含多个节点的区块链系统对多比特数据进行共识的问题,并能在共识过程中应对任意多恶意节点的攻击,提高了区块链系统的安全性.
Quantum technology can empower blockchain technology and improve the security performance of the blockchain consensus protocol.According to whether there is an honest independent quantum source device(QSD),we propose two numerical list distribution methods with high success rate for multiple nodes,and further propose a new quantum detection Byzantine protocol based on numerical list distribution.A consensus example of four nodes verifies that the proposed protocol meets the conditions for detecting Byzantine protocols.Finally,through analysis and comparison,the proposed protocol has better practicability and security.Compared with other protocols,the consensus protocol proposed in this paper can not only solve the problem of multi-bit data consensus in the blockchain system containing multiple nodes,but also deal with the attack of any number of malicious nodes during the consensus process,which improves the security of the blockchain system.
