Trusted authentication method for image input equipment, and image input equipment thereof

Abstract

The invention discloses a trusted authentication method for image input equipment. The trusted authentication method comprises the following steps that: the image input equipment is connected with a host so as to obtain a power supply; the image input equipment performs self-check of an equipment certificate of the image input equipment; when the self-check is passed, first communication connection between the image input equipment and the host is established; the image input equipment generates a random number and detects the security of the random number; the image input equipment calculates an error detection code of a storage content in a storage area, detects the integrity of the storage content in the storage area according to the error detection code obtained by calculation, and performs hash algorithm of first detection data; the image input equipment detects the security of the hash algorithm according to a hash operation result, and encrypts and decrypts second detection data; the image input equipment detects the security of an encryption and decryption algorithm according to an encryption and decryption operation result; if the encryption algorithm is secure, second communication connection between the image input equipment and the host is established; and the image input equipment receives a read-write command from the host.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a credible authentication method of an image input device and an image input device thereof. Background technique [0002] With the development of technology, more and more devices are becoming portable. The image input device is often connected to the computer and transfers files, and it is easy to infect the hidden virus in the computer, so that the computer can modify the firmware of the image input device, damage its own device or attack the system of other computers connected to it through the image input device. . Summary of the invention [0003] The object of the present invention is to provide a method and an image input device that can realize the credible authentication of an image input device so as to prevent the image input device from attacking the computer system connected to it. [0004] In order to achieve the above objective, in the first aspect, the p...
