<p><P>PROBLEM TO BE SOLVED: To provide authentication of either code or data or both, and protected execution environments. <P>SOLUTION: For authentication of code or data, a local storage is dynamically divided and division cancelled. The local storage is divided into an isolated section and a non-isolated section. The code or the data are loaded in the isolated section. Either the code or the data are authenticated in the isolated section of the local storage. After the authentication, the code is executed. After the execution, a memory within the isolated section of an attached processor unit, and the attached processor unit performs division cancellation with the isolated section within the local storage. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
