  • Patent number: 9537656
    Abstract: The present invention relates to key management in a secure microcontroller, and more particularly, to systems, devices and methods of automatically and transparently employing logic or physical address based keys that may also be transferred using dedicated buses. A cryptographic engine translates a logic address to at least one physical address, and processes a corresponding data word based on at least one target key. The target key is selected from a plurality of keys based on the logic or physical address. A universal memory controller stores each processed data word in the corresponding physical address within a memory. Each key is associated with a memory region within the memory, and therefore, the logic or physical address associated with a memory region may be used to automatically identify the corresponding target key. A dedicated secure link may be used to transport key request commands and the plurality of keys.

  • Publication number: 20070067142
    Abstract: A method of monitoring an entity within a process plant wherein the entity includes a plurality of lower level entities, includes acquiring a plurality of use indices, acquiring a plurality of weighting values, and creating an aggregate use index from a combination of the lower level use indices and weighting values, wherein the aggregate use index represents status information regarding the entity. Each use index pertains to status information regarding one of the plurality of lower level entities, and each weighting value pertains to the importance of a lower level entity among the plurality of lower level entities.
