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.

摘要:实战条件下如何评价短波跳频通信系统的抗干扰性能是构建短波跳频通信系统的重要环rr-}J。由于不 能得到精确的指标评价值，采川组合赋权法给出了系统抗干扰性能的评价算法已经不能适川。给出了一种模糊综 合评价方法，该方法有如下优点:为避兔专家赋指标权值的卞观随意性，将德尔菲(Delphi)法和层次分析法(AHP)相结合来确定指标权值 为了便于专家较准确地作出评判，给出了指标评价等级，并利川模糊评价法给出指标评价矩 阵，最后得到评价结果。评价实例表明了该方法的有效性。 -Abstract: how to assess the actual conditions of short-wave frequency-hopping communication system anti-jamming performance is short-wave frequency-hopping communication system to build an important ring rr-) J. Can not be accurate due to evaluate the value of mining Kawasaki combination weighting approach gives a systematic evaluation of anti-interference performance can no longer be appropriate algorithm Chuan. This paper presents a fuzzy comprehensive evaluation method that has the following advantages: In order to avoid the rabbit experts give the right indicator of the value of randomness Bian concept will Delphi (Delphi) and Analytic Hierarchy Process (AHP) to determine the combination of the right indicators value in order to facilitate t

无刷电机是在嵌入式系统中广泛使用的动作机,文章给出了一种巧妙的无刷电机驱动方法,并且提供了驱动电机所需的汇编代码,用便捷廉价的方法,实现了无刷电机的驱动,而且有一个关键优势:不需要传感器!-brushless motor is in embedded system widely used in aircraft movements. The article gives a deceptively brushless motor drive, and provides the necessary drive motor assembly code, with convenient and cheap method to achieve a brushless motor drive, but is a key advantage : no need for sensors!
