Abstract
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.
