ABSTRACT:
The present disclosure provides a method for scalable anti-replay windowing. According to one exemplary embodiment, the method may include receiving at least one data packet having at least one new sequence number. The method may also include comparing the at least one new sequence number to an anti-replay window configured to prevent packet replay, the anti-replay window having at least one existing sequence number. The method may further include shifting the contents of the anti-replay window by varying the location of a starting index and an ending index. Of course, additional embodiments, variations and modifications are possible without departing from this embodiment.
