PPP挑战握手认证协议(CHAP)，PPP【1】提供了点到点链路传输多协议数据报的标准方法。 在PPP中也定义了一种可扩展的LCP，允许协商认证协议，从而可以在进行网络层 协议传输之前对对端进行认证。 本文定义了一种PPP认证方法，该方法利用随机“挑战”和依据“挑战”和密钥 计算出的加密哈希“应答”来完成认证。 -PPP Challenge Handshake Authentication Protocol (CHAP), PPP [1] provides a point-to-point link multi-protocol data transmission of standard methods. In PPP also defines a scalable LCP to allow consultations authentication protocol, thereby conducting transmission network layer protocol before the end-to-end authentication. This paper defines a PPP authentication methods, The method using random "challenge" and the basis for "challenge" and calculated key encryption Hash "responsive" to complete certification.

1. 完成时／分／秒的依次显示并正确计数，利用六位数码管显示； 2. 时／分／秒各段个位满10正确进位，秒／分能做到满60向前进位，有系统时间清零功能； 3. 定时器：实现整点报时，通过扬声器发出高低报时声音； 4. 时间设置，也就是手动调时功能：当认为时钟不准确时，可以分别对分／时钟进行调整； 5. 闹钟：实现分/时闹钟设置，在时钟到达设定时间时通过扬声器响铃。有静音模式。 -1. Completed/min/sec display and correctly followed by counting, using six digital tube display 2. When/min/sec in the paragraphs of the correct 10-bit binary full, s/sub can do to advance the age of 60-bit, systematic function of the time cleared 3. timers: realize the whole point of time, by the time the level of sound from loudspeakers 4. time settings, which is manually adjusted when the function: When the clock does not consider accurate, they can respectively sub/clock adjustments 5. alarm clock: the realization of sub-/ when the alarm clock settings, settings in the clock arrival time ringing through the loudspeakers. There are silent mode.
