Cryptography has been around for hundreds of years. The measure of how good a cryptographic cipher is determined by the likelihood of collisions occurring. Find at least two vulnerable cryptographic methods and discuss the reason for the vulnerability.

Specifically discuss:

If possible, what steps are needed to improved the cryptographic cipher to ensure security.

If the method is still in use.

Solution

technique 1

RSA TECHNIQUE: The vulnerabilities here are that the public key can be used by anyone other than the receiver.anyone can encrypt anything in this public key.

technique 2

Diffie hellman exchange: this technique is vulnerable to man in the middle attack and eaves dropping where the 3rd party or the unauthorised person can secretly listen to the conversation or can secretly read the messages send between the sender snd intended receiver and man in middle attak means the attacker secretly relays and possibly changes the communication between two parties who believe they are directly communicating with each other.
