摘　　要：针对目前普遍存在的身份认证密码易被破解的问题,本文提出一种基于物理噪声源的动态身份认证系统。该系统将编码后的随机密码通过无线通讯的方式传送给合法用户,这既使得攻击者不可能推断出下一口令,又解决了已有的一次一密认证系统给用户带来的麻烦和负担。此外,系统还提供了无线报警提示功能,可将用户的登录信息及时地发送给对应的合法用户,从而能够有效地主动防止非法用户的假冒攻击行为。Considering that the popular identification systems with fixed passwords are very fragile, an identity authentication system with variable passwords based on a white noise device is presented in this paper. In this system , the random sequence generated by the white noise device is transformed into dynamic passwords, which will be sent to valid users by means of radio. Not only is it impossible to be cracked by deducing the next password from a sequence of known passwords, but also it removes the trouble brought by current one-time-one-password identification systems. Besides, the system provides the radio alarm function, which enables valid registered users to receive the login information and discover the masquerade behavior of invalid users in time.
