ABSTRACT:
A hacking prevention system and method wherein the descrambler receives a data stream including a series of authorization packets and a series of corresponding offset values. A random number is generated in the descrambler. Using this random number, a key is calculated, which corresponds to the authorization packet corresponding to the generated random number. This generated key and the offset value, which corresponds to the generated random number, are used to calculate the descrambling key.
