考题 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.A.CryptographyB.decodeC.privacyD.security@@@SXB@@@A.ConductionB.confidenceC.confidentialityD.connection@@@SXB@@@A.AuthenticationB.structureC.encryptionD.exchange@@@SXB@@@A.AlgorithmB.SecureC.structureD.encryption@@@SXB@@@A.ConfidentialityB.integrityC.serviceD.robustness
