Embodiment Construction

[0015] figure 1 It is a schematic diagram of the hardware structure of a system for encrypting and decrypting an electronic device through an external device of the present invention. A system for encrypting and decrypting electronic devices through external devices (hereinafter referred to as "encryption and decryption system") 50 includes an electronic device 1 and an external device 10. The electronic device 1 is a device that needs to be decrypted to be turned on, such as a computer or a mobile phone. In this embodiment, the components of the electronic device 1 that are not related to the present invention are not shown in the figure. The electronic device 1 includes a first communication serial port 2 and an embedded processor 3. The embedded processor 3 is used to control the electronic device 1 to communicate with the external device 10, and decrypt the electronic device 1 to enter the power-on state. The external device 10 includes a second communication serial port ...

Abstract

An electronic apparatus, a peripheral device, and a system for encrypting and decrypting the electronic apparatus via the peripheral device are provided. The electronic apparatus stores a password which a user sets in a ROM of the electronic apparatus and writes the password to the peripheral device. Only when the electronic apparatus is connected to the peripheral device, the electronic apparatus fetches a password from the peripheral device, and if the electronic apparatus determines that the fetches password is the same as the stored password in the electronic apparatus, the electronic apparatus performs a function of turning on or unlocking the electronic apparatus.

Description

Technical field [0001] The present invention relates to an encryption and decryption system, and more specifically, to a system for encrypting and decrypting an electronic device through an external device. Background technique [0002] At present, the way to set the login password of the computer is nothing more than keyboard input, face recognition, etc. on the computer side. However, the above-mentioned boot and unlock methods recognized on the computer side can easily be stolen by the application program, resulting in Information leakage, and when the computer is shut down, hackers often wake up the computer through the network to steal user information from the computer. Summary of the invention [0003] In order to solve the above-mentioned problems, the purpose of the present invention is to provide a system for encrypting and decrypting an electronic device through an external device. The system includes an electronic device and an external device. Both the electronic devi...
