Abstract: A circuit generally comprising a plurality of master modules and a supervisor module is disclosed. The supervisor module may be configured to (i) detect a target address and a particular master module of the master modules initiating a transaction on a bus, (ii) identify a predetermined authorization in response to the particular master module, the target address and a current security mode of at least three security modes and (iii) subvert the transaction in response to the predetermined authorization restricting the transaction.

Abstract: A circuit generally comprising a first memory, a processor and a logic block is disclosed. The first memory may store (i) a write instruction to store a non-highest security value of at least three security values in a register and (ii) a jump instruction to a second memory. The processor may have a pipeline and may be configured to (i) bootstrap to the first memory while the register stores a highest security value of the security values and (ii) execute the jump instruction following the write instruction. The logic block may be configured to (i) detect the write instruction in an execution stage of the pipeline and (ii) store the non-highest security value in the register in response to detecting the write instruction in a write back stage of the pipeline.

Abstract: A circuit generally comprising a logic module and a security module is disclosed. The logic module may be configured to set a plurality of values to a plurality of predetermined values respectively while in a scan mode. The security module may be configured to (i) disable a scan capability of the values while in a non-lowest security mode of at least three security modes and (ii) enabling the scan capability while in a lowest security mode of the security modes.

Abstract: In one embodiment, the present invention provides for receiving security events from a network device by a distributed software agent of a network security system, determining a priority of each received security event, and storing the security events in a plurality of prioritized event buffers based on the determined priorities for a period of time determined by a timer. Upon expiration of the timer, a batch of security events for transport to a security event manager of the network security system can be created by including security events in the batch in order of priority until the batch is full.

Abstract: In a method for generating a second data stream from a first data stream, which comprises a first header and a first payload data block with payload data, the first header is initially extracted from the first data stream. Subsequently the second header for the second data stream is generated. Then, at least a part of the first header is entered into the second header, the part of the first header including information, which allows conclusions as to the origin of the payload data. Finally, the second payload data block is generated, which comprises the same payload data, so as to obtain the complete second data stream. The method according to the invention enables device-specific encrypting of payload data, a flexible, device-specific “copy” for other devices of a user and, in particular, complete documentation of the origin of the present copy, such that effective copyright protection may be realized.
