Method and system for remote storing processing of data

Abstract

The utility model discloses a method and a system for remote storing processing of data. The method comprises that when a terminal uploads files stored locally to a file server of a network side, a client of the terminal initiates an access authentication request to the file server based on a digital certificate which is acquired in advance, the client accesses the file server after successful authentication, the client generates a dialog key randomly and conducts data encryption to files through the dialog key, a cyphertext is obtained, the client conducts data abstracting mathematical operation by using a cryptographic hash algorithm, the file summary is generated, the client conducts the encryption to the dialog key and the file summary by using a common key of the data certificate, authentication information is obtained, the authentication information is added to a preset position of the cyphertext, and an encryption file is obtained and written to the file server. By the aid of the method and the system, file data of a user is prevented from eavesdropping and stealing illegally during remote store, and the safety of data remote store is improved.

Description

technical field [0001] The invention relates to Internet technology, in particular to a method and system for remote storage and processing of data. Background technique [0002] With the development of global informatization, Internet applications have been widely popularized. Security risks brought about by the openness of the Internet and the complexity of application systems have also increased. The majority of individual and corporate users are facing security threats such as viruses, Trojan horses, and hackers, and the security of personal information is facing threats such as theft and leakage. important security threat. [0003] Although some users use encryption software to encrypt their important information and store it locally, which can resist the risk of information leakage caused by hacking to a certain extent, but there are still cases where files on this computer are illegally deleted or lost, and it is difficult to restore the original files. There are da...

Problems solved by technology

[0005] However, in the process of realizing the present invention, the inventors found that in the existing network storage services, almost no encryption method is used to store the user's personal file data, even if there is a network disk service to store the user's personal file data encryption, the encryption method is relatively simple, and it is easy to be cracked, resulting in illegal theft of the user's personal file data during storage; moreover, none of the existing network storage services protects the user's personal file data during transmission to the file server. Data is encrypted, which leads to illegal eavesdropping and stealing of personal file data during transmission, which poses a great security threat to users
