Embodiment Construction

[0021] With the accompanying drawings, through the following detailed descriptions and examples, the various viewpoints of all the embodiments disclosed in the present invention can be better understood.

[0022] FIG. 1 shows a schematic diagram of an electronic device with an authentication mechanism. In FIG. 1 , the electronic device is represented by a mobile phone 12 , but it is not intended to limit the present invention. The mobile phone 12 includes a baseband chip 13 , an external random access memory (external RAM) 16 and an external flash memory (external flash memory) 17 . The baseband chip 13 further includes an internal random access memory (internal RAM) 14, a boot read-only memory (boot ROM) 15, and a processor 18, wherein the processor 18 can execute and store in the internal random access memory 14, the boot read-only memory 15 , the program in the external random access memory 16 and the external flash memory 17. The program in the boot ROM 15 (also known as...

Abstract

An embodiment of an apparatus for downloading and / or executing programs from a tool resident on a computer host is disclosed. The apparatus comprises an external flash memory storing a program, and a processor for validating the tool when detecting that the computer host connects to the apparatus. The processor permits the computer host to update the program of the external flash memory after determining that the tool has been successfully verified.

Description

technical field [0001] The present invention relates to an authentication mechanism, in particular to an authentication mechanism executed by a device to authenticate a program in a computer host. Background technique [0002] Many currently widely used electronic devices (such as mobile phones, etc.) have increasing requirements for data and software security. For the existing design, due to the lack of relevant authentication mechanism, the system software embedded in the electronic device can be easily replaced, copied or invaded. In order to solve this problem, most of the solutions are to record the developer information in the chip embedded in the electronic product in advance. However, this approach increases processing complexity and causes inventory problems for chip manufacturers. Contents of the invention [0003] In order to solve the problem of increased processing complexity and inventory of chip manufacturers due to the need to record developer information...
