Abstract
The present specification discloses systems, methods, and a computer tangible medium storing instructions for a collision resistant process for thwarting birthday attacks. A birthday attack is a type of cryptographic attack that exploits mathematical collisions that result when different messages are hashed by a hash algorithm, but produce the same hash digest, which can render computer security systems vulnerable to hacking. By hashing files in different orders with the same hash algorithm, the systems, methods, and mediums disclosed herein can distinguish between identical files and different files that produce a collision when hashed in one order as the collision is not replicated when those different files are hashed in a different order as they are when the files are the same.
