按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model

条形码编码算法，可以输出多种形式条码-barcode coding algorithm, can output multiple forms barcode

　提出一种改进的禁忌搜索算法来求解背包问题。该算法基于禁忌搜索技术,并采用I&D策略,同时设计了两种针对局 部最优解的变异算子。改进后的算法能有效地弥补标准禁忌算法对初始解依赖的缺陷,同时也避免了搜索停滞的现象。通过对具 体实例和随机问题的测试,表明改进后的禁忌搜索算法有更好的性能。 关-An improved tabu search algorithm to solve knapsack problem. The algorithm is based on tabu search techniques, using I & D strategies, while designed for the local optimal solution of the two kinds of mutation operator. The improved algorithm can effectively compensate for the standard tabu search algorithm depends on the initial solution defect, but also to avoid the phenomenon of search stagnation. Through specific examples and random-question test, indicating that the improved tabu search algorithm has better performance. Guan

这里介绍了利用Microsoft CryptoAPI 实现AES加密的技术要点-Introduce here the use of Microsoft CryptoAPI realize AES encryption techniques

是当今比较新的算法MD5，比DES和DES5都要加密好，是dll文件，在自己写的程序中加入它，就可以直接用了，全是意接口的形式-Is the relatively new algorithm MD5, should DES5 than DES and encryption, and is a dll file, written in their own process to join it, can be directly used, the interface is intended to form ~ ~ ~ ~

2的16次幂正整数d与n，编写计算d-1 (mod n) 的程序； 2、对于三个不超过2的16次幂正整数a、e与n，编写计算ae (mod n) 的程序。 在上述程序基础上写出下列程序： （1） 对给定的10000以内数判定其是否为素数； （2） 进行ElGamal体制的加密与签名。 -two of 16 power-positive integer d and n, calculate the preparation of d-1 (mod n); 2. For not more than 2 3 16 Powers positive integers a, e and n, calculate the preparation ae (mod n) procedures. In the above procedure to write on the basis of the following procedures : (a) the right to 10,000 within a few judging whether a prime number; (2) ElGamal encryption and signature.
