METHOD AND APPARATUS FOR VERIFYING INTEGRITY OF DATA PACKET IN DATA STREAMING CHANNEL Russian patent published in 2012 - IPC H04L29/06 

FIELD: physics, communications.

SUBSTANCE: invention relates to wireless communication and specifically to a method of verifying integrity of a data packet in a data streaming channel. The technical result is achieved due to that in the method, data are received from a data streaming channel. Each data packet includes a data payload and a corresponding message integrity code. The received data packets are processed in a first processing mode, wherein the received data packets are forwarded to an application module before checking the integrity of the data packets using the respective message integrity codes. An integrity-check-failure measurement is generated for monitoring an integrity-check-failure rate in the first processing mode. If the integrity-check-failure measurement exceeds an integrity-check threshold, then the method switches to a second processing mode. A received data packet is forwarded to the application module in the second processing mode only after passing the integrity check.

EFFECT: high efficiency and safety of a data streaming channel.
