  • Patent number: 7908450
    Abstract: A memory management unit manages a memory that stores a code, and sets that the memory that stores the code to be executed is valid to make a processor execute the code stores a verification key used to verify a validity of the code in a verification-key storing unit. When the code is stored in the memory and ready to be executed by the processor, the memory management unit verifies the validity of the code using the verification key stored in the verification-key storing unit and verification information assigned to the code. The memory management unit controls to set that the memory is valid when the validity is verified by the verifying unit, and not to set that the memory is valid when the validity is not verified by the verifying unit.

  • Patent number: 6480963
    Abstract: A network system with integrated security protection facilities. The system involves a transmission unit and a reception unit, which are coupled to each other via a network. In the transmission unit, a data management unit performs centralized management of source data that is stored in a plurality of storage units in a distributed manner. In response to a data transmission request from a terminal local to the transmission unit, a data collection unit collects requested data items from the data management unit. A security processor applies appropriate security protection processes to the collected data, depending on its data confidentiality level. An identification data attaching unit attaches identification data to the transmission data. This identification data informs the recipient of what sequence of security process primitives has been applied to the source data. A transmitter sends out the security-protected data over the network.
