Chip encipher

The invention provides a chip encipher and relates to the technical field of chip encryption. An encryption interface (1) and a detection circuit (2) are both connected with a single-chip microcomputer (9). The encryption interface (1) and the detection circuit (2) are connected. A power circuit (3) and a JTAG interface circuit (4) are connected with the single-chip microcomputer (9). A data storage unit (5) and a serial port-USB switching circuit (6) are connected with the single-chip microcomputer (9). An LCD display circuit (7) and a reference circuit (8) are connected with the single-chip microcomputer (9) and the reference circuit (8) is connected with the detection circuit (2). The chip encipher is scientific and reasonable in design, the good encryption function and the decryption resistance function can be achieved, the largest advantage of encryption is encryption irreversibility, a burned chip can not be decrypted, related software work rights and interests of a developer are fully guaranteed, and t
