| Title of Invention | A CRYPTOGRAPHICALLY SECURE PSEUDO-RANDOM NUMBER GENERATOR AND A METHOD OF OPERATING THE SAME |
|---|---|
| Abstract | A cryptographically secure pseudo-random number generator is configured to obtain one or more unpredictable sources of entropy that provide a seed. A current internal state of the number generator is modified as a function of the current internal state and the seed to accumulate entropy. The modified internal state may be obtained by using non-linear feedback shift register operations on the internal state and the seed. A pseudo-random number is then generated based on the modified internal state of the number generator. The one or more unpredictable sources of entropy may be combined into the seed. The internal state of the number generator may be continually modified with additional seeds obtained from the one or more unpredictable sources and the current internal state. Additionally, the internal state of the number generator may be modified on demand with a new seed received from a calling application. |
