Systems and methods are presented to prevent denial of service attacks through the use of an interleaved pseudo-random sequence that is generated from two or more pseudo-random codes. Portions of the pseudo-random codes are interleaved with each other using a pre-determined instruction pattern. A message incorporating the interleaved sequence is transmitted to a receiver, which identifies the interleaved bit sequence in the message and, if the interleaved bit sequence is identified in the message, allows access to the service.
