Assume that Alice and Bob are using the following authentication protocol (requires only three messages to achieve mutual authentication as shown in Figure-4) for their chat application to establish a session key (K) for each communication. "I am Alice", RAlice RBob [RAlice]Bob (B mod N}Alice [RBob]Alice {A mod N}Bob Alice Bob Figure-4: Authentication protocol being used by Alice and Bob Let, the session key (K) is defined as: K=A*B mod N. Alice is acting as the initiator of the communication. Trudy is a member of the network who can see the communication between Alice and Bob and perform an attack. In this task, you need to discuss the following: 1) How can Trudy perform an attack on the above authentication protocol such that both Alice and Bob authenticate each other, and the session key K is disclosed to Trudy? You must provide necessary diagram of the attack scenario. 2) Is the attack that you have discussed in response to the above question beneficial to Trudy? Justify your answer.
