| Outline of Final Research Achievements |
In a social information infrastructure system in which a large number of LSIs are used, Trojan LSIs might cause invalidation of normal functions, leakage or tampering of confidential information. However, there is no means to guarantee that the manufactured LSI does not contain a Trojan circuit. From the aspect of safety and security as well as economics, we have worked on establishing a technology to distinguish authentic LSI and Trojan LSI as a measure to prevent Trojan LSI.
Two main research topics are as follows. (1) development of a method for generating comprehensive information on the circuit structure within the manufactured LSI, and (2) study on a mechanism for protecting the information of the output circuit structure. By achieving these research topics, we established the basic technology of a mechanism that can distinguish whether the manufactured LSIs are authentic LSIs or Trojan LSIs based on the design data of authentic LSI.
