Abstract
A physical layer device provides security processing on communication frames that may include tags or headers that are for use in a wide area network. As frames pass through the physical layer device, the frames are classified for a type of security processing. Depending on the classification a cipher is applied to the frames for integrity checking of data in the frames. Some frames are also encrypted. The security processing may exclude some of the tags or headers. The frames may also be filtered and buffered.
