Chat System Security using Cryptography

Successfully completed the attack component of the project by breaking three out of four systems using hacking methods non-social programming to disrupt the operation of a chat system developed by other groups. The second part of the project involved development of secure chat system in Java using modified Diffie-Hellman shared key cryptography.

Signal Probability Based Combinational Equivalence Checking

As opposed to the automatic test pattern or BDD based equivalence checking, the probability based approach for equivalence checking assigns probability values to the primary inputs and compares the corresponding output probability of two networks to assert their equivalence.
