ABSTRACT:
Methods and apparatus provide for: reading encrypted boot code from a storage medium into a local memory associated with a first of a plurality of processors; decrypting the encrypted boot code using a trusted decryption function of the first processor such that the boot code is verified as being authentic; booting the first processor using the boot code from the local memory; and authenticating boot code for one or more of the other processors in the first processor prior to the one or more other processors booting up.
