All three types of cryptography schemes

免费题库2022-08-02 91

问题 All three types of cryptography schemes have unique function mapping to specific applications.For example, the symmetric key（　　）approach is typically used for the encryption of data providing（　　）, whereas asymmetric key cryptography is mainly used in key（　　）and nonrepudiation, thereby providing confidentiality and authentication. The hash（　　）（noncryptic）, on the other hand, does not provide confidentiality but provides message integrity, and cryptographic hash algorithms provide message（　　）and identity of peers during transport over insecure channels.问题1选项A.cryptographyB.decodeC.privacyD.security问题2选项A.conductionB.confidenceC.confidentialityD.connection问题3选项A.authenticationB.structureC.encryptionD.exchange问题4选项A.algorithmB.secureC.structureD.encryption问题5选项A.confidentialityB.integrityC.serviceD.robustness

答案 ACDAB

解析所有三种类型的加密方式都有映射到特定应用中的独特功能。例如，对称密钥加密方法典型地用于保障加密数据的保密性，非对称方式主要用于密钥交换和不可否认性场景，因而提供保密性和身份验证。相比之下，哈希算法（不带密钥）不提供保密性只保障消息的完整性，而带密钥的哈希算法保障数据的完整性并且能为点对点信息通过不安全信道传递时提供身份验证。
