Problems solved by technology

That is, in the fifth step of the above process, the file is likely to be tampered with by others during the transmission process; and in the seventh step of the above process, the download device cannot determine whether the content has been tampered with after receiving the file, and After the download is completed, the download device will automatically use the tampered content
Criminals are likely to take advantage of this shortcoming, tamper with the content when users legally download files, inject viruses, Trojan horses, and illegal codes into files for users to download and use, thus threatening the security of users

Embodiment 1

[0060] Such as figure 1 As shown, the processing method for downloading files in the embodiment of the present invention includes:

[0061] S101, receiving the characteristic characters of the file; this step can be:

[0062] (a) receiving file download description information, the file download description carries file characteristic characters;

[0063] (b) Analyzing the file feature character from the file download description information.

[0064] S102, download the file;

[0065]S103, generating a new characteristic character of the file according to the downloaded file;

[0066] The step of generating a new file feature character according to the download request of the file download description information includes but is not limited to the following methods:

[0067] (1) Abstract the content of the file; encode the information after the abstract; for example, after using the SHA (Secure Hash Algorithm, Secure Hash Algorithm) algorithm to abstract the content of the...

Embodiment 2

[0101] A processing method for downloading files, such as figure 2 shown, including:

[0102] S201, the downloading end receives file download description information from the sending end, the file download description carries file characteristic characters, a field indicating whether the downloading end supports the anti-tampering function of the downloaded file, and the URL of the file;

[0103] S202. Parsing, respectively, from the file download description information, a field indicating whether the download end supports the anti-tampering function of the downloaded file, file characteristic characters, and a URL of the file;

[0104] S203. According to the field indicating whether the download end supports the anti-tampering function of the downloaded file, determine whether the download end supports the anti-tampering function of the downloaded file, and perform different processing. If the download end supports the anti-tampering function of downloaded files, proceed ...

Abstract

The embodiment of the invention discloses a processing method for downloading a file and a device thereof, a processing method for assigning a file and a device thereof, and a system for transmitting a file, and belongs to the communication field. The processing method for downloading the file comprises the steps of receiving the feature characters of the file; downloading the file; generating the new feature characters of the file according to the downloaded file; comparing the generated new feature characters of the file and the received feature characters of the file; and performing processing to the downloaded file according to compared results. The embodiment of the invention can be suitable for the processing procedures during the file downloading process, and improve the security of users.

Description

technical field [0001] The invention relates to the communication field, in particular to a processing method and device for downloading files, a processing method and device for sending files and a system for transmitting files. Background technique [0002] OMA (Open Mobile Alliance, Open Mobile Alliance) DLOTA (Download Over-The-Air, download over the air) is a set of specifications formulated by the OMA organization on how mobile devices obtain files from the sending end side through OTA. The purpose of this specification design is to define a set of download protocols with status notifications, so that the sending end side can know the status of downloading files at the downloading end. This downloading method is called OMA downloading. [0003] The basic process of OMA DLOTA protocol download is described below: [0004] Download the search program in the terminal device, find the file of interest, and obtain the relevant pointing information. The pointing information...
