摘要
区块链作为价值传输的使能技术,正在逐步构建去中心化、自组织、共享数据的可信基础设施,重塑现有互联网应用和传统产业。对于区块链基础设施而言,安全加密是维护整个系统安全的核心功能。但随着量子计算等新计算技术的发展,作为区块链底层安全支撑技术之一的传统公钥密码的安全性受到严峻挑战。为解决这一问题,抗量子计算密码应运而生。首先归纳总结了已有的抗量子加密技术,在此基础上提出基于多变量二次方程的Hi MQ-3P快速签名算法以应对量子计算对区块链安全性的冲击。该算法在签名长度、公私钥长度、验证速度等方面性能都有所提升。最后将该算法与其他现有算法通过多个维度进行了比较分析。
As an enabling technology for value transmission,blockchain is gradually building a decentralized self-organizing and data sharing credible infrastructure,which reshapes current Internet applications and traditional industries. For blockchain infrastructure,secure encryption is the key function that maintains the security of the entire system. However,with the development of new computing technologies such as quantum computing,the security of traditional public key cryptography,which is one of the underlying security support technologies of blockchain,is severely challenged,and anti-quantum computing passwords came into being. This paper firstly summarizes the existing anti-quantum encryption technology. On the basis,the Hi MQ-3 P fast signature algorithm based on multivariate quadratic equation is proposed to cope with the impact of quantum computing on the blockchain security. The algorithm improves performance in terms of signature length,public and private key length,verification speed and so on. Finally,we compare the proposed algorithm with other existing algorithms through multiple dimensions.
