摘要
在物联网和电子商务的快速发展下,安全问题日益凸显,首先要解决的就是身份认证问题,而动态密码技术能有效解决这一问题。文中对一动态密码算法进行改进,实现了双向认证。方案基于CPK算法,采用挑战/应答机制,提供更加安全的身份认证。
With the rapid development of the Intemet of things and e-commerce, the security problem is becoming significant. The first to solve is the identity authentication, to which the dynamic password technology is an effective solution. In this paper, we improve a dynamic password algorithm, and implement the bidirectional authentication. The scheme based on CPK algorithm provides more secure authentication with the challenge/response mechanism.
