  • Publication number: 20080168533
    Abstract: A program verification apparatus includes a storing which stores a plurality of statements in correspondence with values of respective risk levels of the statements. Referring to a signature included in a signed module, a value indicating a risk level of the signed module is obtained. A to-be-verified program including a plurality of statements or signed modules is input to the apparatus. Values of first risk levels of the statements included in the to-be-verified program are determined by referring to the storing device. Values of second risk levels of the signed modules included in the to-be-verified program are also determined. Then, a maximum value of a risk level of the to-be-verified program is calculated from the values of the first risk levels and the values of the second risk levels. A verification result including the maximum value of the risk level is outputted accordingly.

  • Publication number: 20080046763
    Abstract: In the method for sharing encrypted data region among two or more processes on a tamper resistant processor, one process creates the encrypted data region to be shared according to the common key generated as a result of the safe key exchange, and the other process maps that region to its own address space or process space. The address information of the shared encrypted data region and the common key of each process are set in relation in the encrypted attribute register inside the tamper resistant processor, so that it is possible to share the encrypted data region safely.
