A session key never passes across the network.C. A session key is used as the key for asymmetric data encryption.D. A session key is used as the key for symmetric data encryption.
Symmetric, or private-key, encryption is based on a secret key that is shared by both communcating parties. The （ ） party uses the secret key as part of the mathematical operation to encrypt （ ） text to cipher text. The receiving party uses the same secret key to decrypt the cipher text to plain text. Asymmetric, or public-key, encryption uses two different keys for each user: one is a （ ） key known only to this one user; the other is a corresponding public key, which is accessible to anyone. The private and public keys are mathematically related by the encryption algorithm. One key ia used for encyption and the other for decryption, depending on the nature of the communication service being implemented. In addition, public key encryption technoligies allow digital （ ） to be placed on messages. A digital signature uses the senders private key to encrypt some portion of the message. When the message is received, the receiver uses the senders （ ） key tp decipher the digital signature to verify the senders identity.A.host B.terminal C.sending D.receiving A.plain B.cipher C.public D.private A.plain B.cipher C.public D.private A.interpretation B.signatures C.encryption D.decryption A.plain B.cipher C.public D.private
