The bag was too heavy and she just couldn’t lift it up. The man behind her got very impatient. He, too, was waiting to check in his luggage. “What’s wrong with this girl?” He said, “Why doesn’t she hurry up?” He moved forward and placed his bag on the counter, hoping to check in first. He was in a hurry to get a good seat. Maria was very angry, but she was very polite. And in her best English she said, “Why are you so upset? There are enough seats for everyone on the plane. If you are in such a hurry, why can’t you give me a hand with my luggage?” The man was surprised to hear Maria speak English. He quickly picked up her luggage and stepped back. Everyone was looking at him with disapproval. 6、Maria’s story happened on her way back to Santo Domingo. A、T B、F 参考答案:B

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。
