Title: Dynamically configurable interleaver scheme using at least one dynamically changeable interleaving parameter

Abstract: A method for encrypting and decrypting an original data stream comprising: (A) transmitting a copy of a key to an interleaver and to a de-interleaver, wherein the key includes a key-algorithm configured to describe an evolution in time of at least one interleaving parameter; (B) interleaving the original data stream by using the interleaver, wherein the interleaver compensates for a change in latency caused by at least one dynamically changeable interleaving parameter; and (C) recovering the original data stream from the interleaved data stream propagated through the communication channel by using the de-interleaver adapted to communicate with the communication channel, wherein the de-interleaver compensates for a change in latency caused by at least one dynamically changeable interleaving parameter.
