Create a simulator

Hi , Basically, I need a simulator that able to read and run the communication protocols (mainly target on authentication) from user and allow user to run a series of attacks on it to analyse if the protocol is vulnerable or not. - user is required to select how numbers of parties would be involve in the "communication" and identify it with an alphabet. i.e. "A", "B", "T" etc.. - user will input a [login to view URL] file with protocols written in it. (according to the simulator definition) - simulator able to read in definition and represent each of the parties (A, B, T...) with an object and communicate with each other. - GUI that shows the protocol is running step by step. - user can input another [login to view URL] file that include how to trigger the attacks (modify, replace, delete, intercept), on which line or sequence, etc... - results shown, if the attack works or not. That's what I have been thinking of... I am not sure if it would work or not as I am not familiar with this field. I would welcome any suggestions as you have more experiences in this.
