  • Methods, apparatus, and systems for secure demand paging and other paging operations for processor devices
    Patent number: 10853269
    Abstract: A secure demand paging system including a secure internal memory, an external non-volatile memory having encrypted and integrity-protected code pages, an external volatile memory for swap pages and a processor coupled to said secure internal memory and to said external non-volatile memory and operable to decrypt and verify the integrity of the code pages thereby to transfer code pages to said secure internal memory directly from said external non-volatile memory bypassing said external volatile memory in respect of the code pages, and to swap out and swap in the swap pages between secure internal memory and said external volatile memory bypassing said external non-volatile memory in respect of the swap pages for said external volatile memory.

  • Host/battery with public/private busses, public memory, processor, and private memory
    Patent number: 10740495
    Abstract: Systems and methods for providing a battery module 110 with secure identity information and authentication of the identity of the battery 110 by a host 120. In one embodiment, the system for providing a battery module with secure identity information includes: (1) a tamper resistant processing environment 200 located within the battery module 110 and (2) a key generator configured to generate a key based on an identity of the battery module 110 and cause the key to be stored within the tamper resistant processing environment 200.
