Abstract

Embodiments of the invention are generally directed detection of encryption utilizing error detection for received data. An embodiment of a method includes selecting a first port for foreground processing of a stream of data received at the first port, the stream of data including content data, and sampling a set of data received at a second port, the second port being not selected for foreground processing, the set of data including a data packet and error correction data. The method further includes performing background processing of the set of data, wherein the background processing includes decrypting data of the data packet and utilizing the error correction data to determine whether the data packet contains an error, and determining whether data received at the second port is encrypted based at least in part on the determination whether the data packet contains an error.
