Explain the disadvantage of private key encryption and how public key encryption overcomes the problem.
What will be an ideal response?
Private key encryption uses the same key for coding and decoding. Therefore, control over the key becomes an important security issue. When several individuals need to exchange encrypted data, the chance that the private key will become known to an intruder is increased. To overcome this problem, public key encryption was devised. This approach uses two different keys: one for encoding messages and the other for decoding them. The recipient has a private key used for decoding that is kept secret. The encoding key is public and published for everyone to use.
