Method and device for object file verification

Abstract

Embodiments of the present invention provide a method and device for verifying a target file, wherein the method includes: a host computer downloads the target file; the host computer performs verification on the target file to obtain a first verification result; The upper computer sends the target file to the lower computer; the lower computer is used to verify the target file to obtain a second verification result; the upper computer receives the second verification result sent by the lower computer ; The upper computer judges whether the first verification result is consistent with the second verification result; if so, the upper computer determines that the target file download is successful; if not, the upper computer determines that the Destination file download failed. The embodiments of the present invention are used to quickly verify downloaded files, save verification time, reduce computing resources required for verifying files, and ensure the correctness of downloaded files.

Description

technical field [0001] The invention relates to the technical field of memory data processing, in particular to a method for verifying an object file and a device for verifying the object file. Background technique [0002] With the rapid development and wide application of various electronic devices and embedded systems, such as computers, personal digital assistants, mobile phones, digital cameras, etc., there is a great need for a device that can be programmed many times, has a large capacity, is fast to read and write, and can be erased. Convenient, simple, less peripheral devices, low-cost memory. [0003] In the process of downloading files in batches from the memory, in order to ensure the correctness of the downloaded files and the security of the downloaded files, it is usually necessary to verify the downloaded files. However, in the traditional verification method, the upper computer needs to download the file downloaded to the lower computer, and then download i...

Problems solved by technology

However, in the traditional verification method, the upper computer needs to download the file downloaded to the lower computer, and then download it again from the lower computer, so as to verify the correctness of the file downloaded by the lower computer. It is understandable that the traditional verification method requires It takes a long time to verify and the efficiency is low

But in reality, in order to obtain the greatest economic benefits, it is necessary to quickly verify the correctness of downloaded files, thereby saving time, improving efficiency, and reducing the computing resources required for verifying files. Obviously, traditional verification methods can no longer meet the existing demand
