<P>PROBLEM TO BE SOLVED: To guarantee secure execution of a computer against various types of threats. <P>SOLUTION: An apparatus for secure execution using a secure memory partition comprises: a non-volatile memory to store a verification execution instruction 242; a system memory 220 having a secure partition 223; and a processor 210 coupled to the non-volatile memory and the system memory 220. The processor 210 comprises: an on-chip basic input/output system (BIOS) 215 including a bootstrap security logic 241; and an execution unit 211 coupled to the on-chip BIOS 215 and the system memory 220 and configured to perform operation specified by the bootstrap security logic 241. The operation includes a step of copying the verification execution instruction 242 from the non-volatile memory to the secure partition and a step of verifying the authenticity of the verification execution instruction 242. <P>COPYRIGHT: (C)2012,JPO&INPIT |
