<p><P>PROBLEM TO BE SOLVED: To provide a computer for detecting any virus infecting a system area such as MBR (Master Boot Record) before an OS starts, and restricting (or prohibiting) the use of the computer in an environment that does not satisfy environmental conditions set in advance. <P>SOLUTION: In a PC with an encryption hardware module and an encryption hard disk which are defined by TCG (Trusted Computing Group), a BIOS (Basic Input/Output System) calculates a hash value of a program in an accessible area without authentication of the encryption hardware, stores the hash value in the encryption hardware module and supplies it to the program. The program performs an authentication process for the hard disk, and performs a virus check after the authentication. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
