Hello students, today we will discuss about the security attacks on the diffie -hellman key exchange protocol.
00:23
So here, first of all, we are going to discuss about the security attacks on the diffie -hellman key exchange protocol.
00:33
So the attacks against the diffie -hellman key exchange protocol.
00:39
Comes in the given few flavors.
00:42
So here, the first one is daniel of service attack.
00:53
So here, the attacker will try to stop the device and bob from the successfully carrying out the protocol and the attacker can accomplish it in many other ways as example by deleting those messages that are allies and bobs sent to each other or by overwhelming the parties with unnecessary computation or communication.

The second one is outsider attacks, that is the attacker tries to disrupt the protocol so that get some interesting knowledge, that is the information he could not have gathered by just looking at the public values.
02:00
And the third one is insider attacks.
02:06
So it is possible that one of the participants in a delta h protocol, creates a breakable protocol run on the purpose in order to try to gain the knowledge about the secret key of his peer...
