Abstract
Disclosed is a method for verifying data packet integrity in a streaming-data channel. In the method, data packets are received from the streaming-data 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 transitions 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.
