A graphical simulator for the cryptanalysis of block ciphers

We have designed and implemented a graphical simulator for the use of students in the Master of Applied Science (information security) program at RMIT University in Melbourne, Australia. During this process, a lot of practical experience was gained which aids future designers who address similar problems, especially if the design aims include the realistic simulation, in a reasonable time, of a process, cryptanalysis - which often takes many days or weeks of computation by powerful computers.
