第1题:
● 下面安全算法中,属于加密算法的是 (54) ,属于报文摘要算法的是 (55) 。
(54)
A. MD5和3DES
B. MD5和 SHA1
C. DES和SHA1
D. DES和 3DES
(55)
A. MD5和3DES
B. MD5和 SHA1
C. DES和SHA1
D. DES和 3DES
试题(54)、(55)分析
本题考查安全算法相关常识。
数据加密的基本过程就是对原来为明文的文件或数据按某种算法进行处理,使其成为不可读的一段代码,通常称为“密文”,使其只能在输入相应的密钥之后才能显示出本来内容,通过这样的途径来达到保护数据不被非法人窃取、阅读的目的。
常见加密算法有DES(Data Encryption Standard)、3DES(Triple DES)、RC2和RC4、IDEA(International Data Encryption Algorithm)、RSA。
报文摘要算法主要应用在“数字签名”领域,作为对明文的摘要算法。著名的摘要算法有RSA公司的MD5算法和SHA1算法及其大量的变体。
参考答案
(54)D(55)B
