摘要: 身份认证中广泛使用了一次性口令机制。该文分析了一种一次性口令认证方案,指出了其存在的不足;将混沌理论中混沌序列的技术应用到一次性口令当中,提出了一种新的一次性口令方案,该方案实现了双向认证,并在认证时间和存储空间上的开销得到了优化,提高了认证的强度和安全性。

Abstract: One-time password authentication method is widely used in identity authentication. This paper analyses a one-time password authentication protocol and points out its deficiency. It applies the technology of the chaos array in the chaos theory to the OTP method and proposes a new OTP method. This new scheme realizes mutual authentication and also optimizes in time and storage. The new method improves the intensity and the security of authentication.

Key words: Identity authentication, One-time password, One-way function, Chaos array
