Q. Security and Reciprocity of RSA?
Security and Reciprocity of RSA
- Kp and N are issued publicly.
- Ks is kept secret.
- Since the snooper does not know p and q, they would first need to use N to first find p and q and then guess Ks.
- Since N is a few hundred digits long, it is very time consuming and difficult to deduce.
- Same secret key may be used to send a reply and the receiver may decrypt using its own private key.
