Abstract
The utility model discloses a software encryption lock which comprises a central processing unit (CPU), a nonvolatile memory and an interface unit. The interface unit is used for being connected with a host machine of operational software. The nonvolatile memory is used for storing configuration files, and the CPU is used for processing software commands and loading the configuration files from the nonvolatile memory. According to the software encryption technical scheme, a software interface and the functional configuration files are wrote into the encryption lock for protection. For pirated software, if only a software package is embezzled, software functions can not be configured even if an analog interruption method is used, and therefore the part expected to be confidential can not operate normally. Meanwhile, due to the fact that the software configuration files are highly professional, the software functions still can not be configured normally because of different paths even if the configuration files are copied, the software also can not be used normally, and thus reliability of software protection is guaranteed.
