If the whole system depends on on security of one private key and if this key for any reason compromised, the whole system will be compromised . any one can give a suitable name to such attack ?

          Give a suitable name




          I would call this class of attacks: Master key compromise.

            It is not an attack model while it is a security feature for a scheme. The adversary might be able to compromise these lack of secrecy by different attacks to obtain the master key and find other session keys.
            Take a look at this question.

            • There are different ways to obtain that in a specific agreement key protocol. One of the most famous is the Man-in-The-Middle attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other to know the first (master) key between them. Also, side-channel attack is another one if the attacker has access to the crypto system is able to try for obtaining the master key, reply attack and so on. You should evaluate one of them is applicable by considering different features for each security system.
