摘要： A mechanism is provided for masking a boot sequence by providing a dummy processor. With the mechanism, one of the processors of a multiprocessor system is chosen to be a boot processor. The other processors of the multiprocessor system execute masking code that generates electromagnetic and/or thermal signatures that mask the electromagnetic and/or thermal signatures of the actual boot processor. The execution of the masking code on the non-boot processors preferably generates electromagnetic and/or thermal signatures that approximate the signatures of the actual boot code execution on the boot processor. One of the non-boot processors is selected to execute masking code that is different from the other masking code sequence to thereby generate a electromagnetic and/or thermal signature that appears to be unique from an external monitoring perspective.

摘要： A system and method for masking a boot sequence by running different code on each processor of a multiprocessor system are provided. With the system and method, one of the processors of a multiprocessor system is chosen to be a boot processor. The other processors of the multiprocessor system execute masking code that generates electromagnetic and/or thermal signatures that mask the electromagnetic and/or thermal signatures of the actual boot processor. The masking code executed by each of the non-boot processors may be different from each other and may be randomly selected from a plurality of masking code sequences stored in a masking code storage device. Each execution of masking code on each of the non-boot processors may generate a different electromagnetic and/or thermal signature such that none of the processors appear to be unique from an external monitoring perspective.

摘要： One of the processors of a multiprocessor system is chosen to be a boot processor. The other processors of the multiprocessor system execute masking code that generates electromagnetic and/or thermal signatures that mask the electromagnetic and/or thermal signatures of the actual boot processor. Such masking may involve running the same boot code as the boot processor but without obtaining access to security information, such as the security key for accessing the system. The electromagnetic and/or thermal signatures generated by the execution of the masking code preferably approximate the electromagnetic and/or thermal signatures of the actual boot code executing on the boot processor. In this way, it is difficult to distinguish which processor is the actual boot processor.

摘要： Boot code is partitioned into a plurality of boot code partitions. Processors of a multiprocessor system are selected to be boot processors and are each provided with a boot code partition to execute in a predetermined boot code sequence. Each processor executes its boot code partition in accordance with the boot code sequence and signals to a next processor the successful and uncompromised execution of its boot code partition. If any of the processors does not signal successful completion and/or uncompromised execution of its boot code partition, the boot operation fails. The processors may be arranged, with regard to the boot operation, in a daisy chain, ring, or master/slave arrangement, for example.

摘要： Pervasive logic is provided that includes a random event generator. The random event generator randomly selects which processor of a plurality of processors in the multiprocessor system is to be a boot processor for the multiprocessor system. A corresponding configuration bit for the randomly selected processor is set to identify the processor as a boot processor. Based on the setting of the configuration bits for each processor in the plurality of processors, a selection of a security key is made. The security key is then used to decrypt the boot code for booting the multiprocessor system. Only the randomly selected boot processor is able to select the correct security key for correctly decrypting the boot code, which it then executes to bring the system to an operational state.
