摘要： A communications system includes a physical layer hardware unit and a processing unit. The physical layer hardware unit is adapted to communicate data over a communications channel in accordance with assigned transmission parameters. The physical layer hardware unit is adapted to receive an incoming signal over the communications channel and sample the incoming signal to generate a digital received signal. The processing unit is adapted to execute a software driver including program instructions adapted to extract control codes from the digital received signal, generate an authentication code, and transfer the control codes and the authentication code to the physical layer hardware unit. The physical layer hardware unit is adapted to signal a security violation in response to the control codes being inconsistent with the authentication code. A method for identifying security violations in a transceiver includes receiving digital data over a communications channel; extracting control codes from the digital received signal; generating an authentication code; transferring the control codes and the authentication code to a physical layer hardware unit of the transceiver; configuring assigned transmission parameters of the physical layer hardware unit based on the control codes; and signaling a security violation in response to the control codes being inconsistent with the authentication code.

摘要： A method and apparatus for controlling access to segments of memory having security data stored therein is provided. A security check unit maintains information for a plurality of segments of memory regarding whether each of these plurality of segments has secure data stored therein. A hint directory maintains information regarding whether any of a plurality of these segments has secure data stored therein. The hint directory is capable of bypassing the security check unit when it receives an address that falls within a plurality of the segments that have been indicated as being free from secure data. When the hint directory determines that a received address falls within one of a plurality of segments that contain secure data, then the address is passed to the security check unit for a closer examination.
