试题3
Perhaps the most obvious difference between private-key and public-key encryption is that the former assumes complete secrecy of all cry to graphic keys, whereas the latter requires secrecy for only the private key.Although this may seem like a minor distinction ,the ramifications are huge: in the private-key setting the communicating parties must somehow be able to share the (71) key without allowing any third party to learn it, whereas in the public-key setting the (72) key can be sent from one party to the other over a public channel without compromising security.For parties shouting across a room or, more realistically , communicating over a public network like a phone line or then ternet, public-key encryption is the only option.
Another important distinction is that private-key encryption sch emesuse the (73) key for both encryption and decryption, whereas public key encryption schemes use (74) keys for each operation.That is public-key encryption is inherently as ymmetri C．This asymmetry in the public-key setting means that the roles of sender and receiver are not interchangeable as they are in the private-key setting; a single key-pair allows communication in one direction only.(Bidirectional communication can be achieved in a number of ways; the point is that a single invocation of a public-key encryption scheme forces ad is tinction between one user who acts as a receiver and other users who act as senders.)。In addition, a single instance of a (75) encryption scheme enables multiple senders to communicate privately with a single receiver,in contrast to the private-key case where a secret key shared between two parties enables private communication only between those two parties.
