Suppose publickey cryptography is used to encrypt the commun

Suppose public-key cryptography is used to encrypt the communications between Alice and Bob. Alice\'s public key is eA, private key is dA; Bob\'s public key is private key is de. Now Bob wants to send a message m to Alice. Describe which keys should be used to encrypt the message and decrypt the ciphertext.

Solution

Answer:- Bob\'s message is encrypted using e_A and when Alice receives message from Bob it is decrypted using d_B

Explanation:-

*In public key cryptography, each user has two keys and each user publishes one key (public key) keeping another key private (private key).

*Consider two users A and B, if A wants to send a message to B , A\'s message is encrypted using B\'s public key. When B receives message from A , it is decrypted using B\'s private key.
