Explanation

The benefits of asymmetric key cryptography are as follows: The benefits of asymmetric key cryptography are as follows: 1.Same key pair is required to have effective communication with all the users of the asymmetric cryptosystem. This makes the algorithm extremely scalable. 2.Asymmetric algorithms provide a key revocation mechanism. This mechanism enables users to be effectively removed from the system by allowing the cancellation of a key. 3.Key regeneration is needed only when a user's private key is compromised. The system administrator invalidates the user's keys if the user leaves the community. During this task, the other keys are not compromised. 4.Asymmetric key encryption provides integrity, authentication, and nonrepudiation. A message signed by the users cannot be repudiated later, if their private key is not shared with the other 5.Key distribution is a simple process. Users make their public key available to anyone with whom they want to communicate. It is not possible to derive the private key from the public key.
