Counter-Illegal Entry Protocols

Counter-Illegal Entry Protocols, also known as 'c-pies', were protocols created by Dr. Halsey.

Creation
Since 2521, UNSC military operating systems had been standardized for over seventy years, leaving them vulnerable to hacking. There were several incidents in which UNSC systems had been hacked, the most prominent being the destroyer. This prompted Dr. Halsey to create new security protocols for the UNSC.

The algorithms were based on already existing translation algorithms.

Adaption
The so called 'c-pies' were created by Dr. Halsey primarily for use in third-generation Smart AIs. This new crop of intellect would allow them to penetrate any system software. A side effect of the protocol was that the AIs could learn to mutate and defend established UNSC operations systems from attacks.
