In a public key, private key cryptography, scheme given below, identify ‘A’ and ‘B’.
(a) A= Pu y , B= Pr x
(c) A= Pr y , B= Pu x
(b) A= Pr x , B= Pu y
(d) A= Pu x , B= Pr y
Edit:
what I know suppose A want to send message to B, it will use B's public key and B will use its private key to decrypt the message.
so how answer is option d?
