摘要
为解决生物认证技术容易受到主动攻击的问题,在区块链技术的基础上,提出一种适用于金融大数据领域的跨域认证模型。通过分析生物认证技术的部分细节问题,指出了该项技术的安全性问题。针对这些安全隐患,以区块链相关技术为基础设计了跨域认证模型的技术细节和认证协议,同时详细分析了该模型的安全性。分析与测试结果表明,该模型具有较强的便携性和较高的效率,可以抵抗中间人攻击和口令猜测攻击。
On the basis of the block chain technology,a cross-domain authentication model for financial big data is proposed to solve the problem that biometric authentication technology is vulnerable to active attack.The security problems that might exist in the biometric authentication technology are pointed out by analyzing its some details.For these security risks,the technical details and authentication protocols of cross-domain authentication model based on block chain technology are designed,and the security of the model is analyzed in detail.The analysis and testing results show that this model has stronger portability and higher efficiency,which can resist man-in-the-middle attack and password guessing attack.
