<P>PROBLEM TO BE SOLVED: To ensure not software security but hardware security for electronic equipment. <P>SOLUTION: In a security system, an AC/DC conversion processing part comprises a first DC/DC converter which generates a boost/step-down voltage against a rated voltage of each power terminal based on a previously configured conversion table in a first storage device, and a main board comprises a second DC/DC converter which generates a reverse boost/step-down voltage against an output voltage of the first DC/DC converter based on a previously configured reverse conversion table in a second storage device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
