Abstract 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.
