A hardware design with the key reconfiguration is proposed based on the DES algorithm, and the FPGA implementation is presented in this paper. Based on the past results of the DES encryption algorithm implementation, due to the relativity between the generation of sub-key and the critical ...
DES全称为Data Encryption Standard,即数据加密标准,是一种使用密钥加密的块算法,1977年被美国联邦政府的国家标准局确定为联邦资料处理标准(FIPS),并授权在非密级政府通信中使用,随后该算法在国际上广泛流传开来。 DES使用简介# 使用DES需要设置加密内容、加密key、加密混淆向量iv、分组密码模式、填充模式。 加密内容: ...

This article is a discussion about the commonly used file encryption graduation design thesis decryption algorithm, this paper will detail about text and file encryption in the process of decryption algorithm used by the method and technology. For the private key and public key passwords are two ki...
The DFE algorithm uses a decision-directed adaptation method. In this method, the output of the equalizer is quantized to the nearest symbol (this is the "decision" part), and this quantized output is used as the desired signal for the adaptation. The error signal is then the difference bet...
la base d’un algorithme STP et de résoudre la topologie physique redondante en une topologie arborescente. Une boucle de transfert (telle qu’une boucle STP) se produit lorsqu’aucun port d’une topologie redondante n’est bloqué et que le trafic est transféré en cercle indéfiniment....
