Summary:A system encrypting method adopting a multiple use supplementary single-chip microcomputer is disclosed. The method adopts a single-chip microcomputer built-in a burning (prevent being read out) program memory instead of a supplementary microprocessor whose function is simple relatively and the software code amount is small (such as a power supply managing supplementary microprocessor) in a multi-microprocessor system. A password verifying according to an appoint encrypting protocol algorithm is added to the main processor program and the supplementary single-chip microcomputer program, thus the program can not be read out and it could not be copied, therefore achieving the purpose of encrypting the system. L'invention concerne un procédé de cryptage système par micro-ordinateur mono-circuit polyvalent d'appoint. Ledit procédé utilise une mémoire de programme figée (ce qui empêche la lecture) intégrée au micro-ordinateur mono-circuit. Les fonctions du micro-ordinateur d'appoint sont relativement simples, et l
