交大网络教育_网络与信息安全第二次作业

网络信息与安全第二次作业 1.一般来说,把一段详细的评述文字加密成一段加密文字,需要多少位DES 密码? 答:DSE一般采用56位长度的Key,所以总共有256种可能,这个数字大约是7.2X1016。 2.假设这种DES切割函数就是不管输入什么值每32位的值都映射成0,那么DES是什么函数又是怎么计算的呢? 答:Feistel密码的核心就是F函数,这个函数依赖S盒的使用,S盒的输出不应该太接近输入位的线性函数。函数F给Feistel密码注入了混淆成分。 3.据说,64位前后交换位置这种DES方法不能提高加密算法的密码强度。不使用复杂的数学理论你能提供一个解释来说明吗? 答:因为输出排列= ( 输入排列) -1,每一个排列都是一个有次序的Bryant-Tree 排列,所以并没有安全上的改善。 4.计算64位的数字加密操作通过使用CBC,k位OFB和k位CFB把它变成一个n位的评述文字。计算所有的加密操作,这些操作不仅仅运行在这个评述文字本身。举个例子n=1024和k =32。 答:密文区段串接(Cipher BlockChaining, CBC) 模式k-位元密文反馈(k-bits Cipher Feedback, CFB) 模式加密运算程序:SR1 = IV C1 = Fj (EK(SR1)) ⊕P1 SRm = Sj (SRm-1) || Cm-1 ;m = 2, 3, 4, …, N Cm = Fj (EK(SRm)) ⊕Pm ;m = 2, 3, 4, …, N C = C1 || C2 || C3, …, CN 解密運算程序:SR1 = IV P1 = Fj (DK(SR1)) ⊕C1 SRm = Sj (SRm-1) || Cm-1 ;m = 2, 3, 4, …, N Pm = Fj (DK(SRm)) ⊕Cm ;m = 2, 3, 4, …, N P = P1 || P2 || P3, …, PN k-位元输出反馈(k-bits Output Feedback, OFB) 模式加密运算乘程序:SR1 = IV O1 = Fj (EK(SR1)) C1 = P1 ⊕O1 SRm = Sj (SRm-1) || Om-1 ;m = 2, 3, 4, …, N Om = Fj (EK(SRm)) ;m = 2, 3, 4, …, N Cm = Om ⊕Pm ;m = 2, 3, 4, …, N C = C1 || C2 || C3, …, CN 解密运算程序:SR1 = IV O1 = Fj (DK(SR1)) P1 = O1 ⊕C1 SRm = Sj (SRm-1) || Om-1 ;m = 2, 3, 4, …, N Om = Fj (DK(SRm)) ;m = 2, 3, 4, …, N Pm = Om ⊕Cm ;m = 2, 3, 4, …, N P = P1 || P2 || P3, …, PN 5.考虑以下这种方法,通过CBC模式加密一个消息。为了加密一个消息,可以使用一个CBC 解码算法。为了解密一个消息,可以使用一个CBC加密算法。这是怎么实现的呢?这种转换方法与一般的CBC模式比起来有多安全呢? 答:这种方式是可以的。这种方式不如通常的CBC模式安全,因为解密算法是,每个密文组分别解密,再与上一个块密文亦或就可以恢复明文。解密算法的输入是明文,这样的安全性就非常低。

1顺序表操作验证 1.1 实验目的 (1)掌握线性表的顺序存储结构; (2)验证顺序表及其基本操作的实现; (3)掌握数据结构及算法的程序实现的基本方法。 1.2 实验内容 (1)建立含有若干个元素的顺序表; (2)对已建立的顺序表实现插入、删除、查找等基本操作。 2一元多项式相加实验 已知A( x )= a0 + a1x + a2x2+ …… + a n x n和B(x) = b0 + b1x + b2x2 +…… + a m x m,并在A( x ) 和B( x ) 中指数相差很多,求A( x ) = A( x ) + B(x) 。 3开发环境 软件平台:Windows XP 软件环境:Microsoft Visual C++ 6.0 最低硬件配置:内存64MB或以上、硬盘3.2G或以上

4 算法设计介绍 4.1 设计思路 分析: 1.存储结构分析 根据一元多项式的特点,要表示一个多项式,只要存储第i 项以及ai 的值,并且如果ai 为0的话,该项就不用存储了,从而减少一个存储空间。在线性表中可以通过顺序和链式存储,并用Ti 表示一个数据项Ti=(ai,i )。下面以图示表示两种存储结构(假设a2=0)。 图1 顺序存储表 图2 单链表存储 以上两个图可知,在存储空间分配量上两种结构是一致的,但如果两多项式相加的话需要频繁的做插入操作,顺序表的结构特性决定了插入操作的时间复杂度为O(n/2),链式表的时间复杂度为O(1),并且如果存储的是一个排好序的多项式的话,不需要双向查找,因此选择单链表存储。 2.相加算法分析 首先,由于两个多项式A(x)和B(x)的指数相差非常多,因此一定要把输入的多项式按照指数i 排好序,防止过高的查找时间复杂度;其次,两个AB 多项式同时从head 开始查找,AB 指数i 相同的计算相加ai 值存入A 表,并且回收不需要的B 空间,指数不同的,B 指数小的节点插到A 指数大的前面。以此往后推移。其时间复杂度为O(n)。 举例: A(x)=2+3x+1x3 B(x)=1+3x+2x2+2x4+12x7+32x8+42x11+2x12 整个相加过程如下: 见注释11 1 Data 区域2[0]表示 该节点的系数为2 指数为0 …
