| Abstract: | A hardware encryption lock used to identify the legality of the software by data exchange with the computer is proposed in this paper. The lock is an intelligent device with micro controller as its core ,modern encryption technology as its security tool, and without effect on printer operation as its principle. Firstly, the theory of data exchange between the computer and the lock is put forwards. Then the software design, authentication protocol and encryption method are described respectively. It can be used broadly in the area of software property protection with features of convenient utilization and confidentialness. |
