Distributed encrypted storage and authentication method based on local area network

Abstract

The invention discloses a distributed encrypted storage and authentication method based on a local area network. The encrypted storage method disclosed by the invention comprises the steps that a distributed management module segments information according to a certain rule, generates a random code based on each segment, carries out weighted confusion based on the segment information, a segment number and the generated random code, and randomly releases the obtained information to a database storage server; and an encryption module encrypts segmented weighting information in a random encryption mode, and then stores the segmented weighting information in a database by a storage module. The authentication method disclosed by the invention is used for carrying out authentication based on the encrypted storage method, and the principle of the authentication method is to carry out segmented encryption on the information again, and then compare the information with actually stored information to judge whether the authentication is successful. The distributed encrypted storage and authentication method disclosed by the invention has the beneficial effects that sensitive information of a user can be effectively stored in a distributed encrypted storage mode to avoid the leakage of all information resulting from the capture of a single storage server.

Description

technical field [0001] The embodiment of the present invention relates to the encrypted storage technology and the corresponding authentication technology of user privacy information in Internet services, which belongs to the field of information security. More specifically, the embodiment of the present invention relates to a distributed encrypted storage and authentication based on a local area network method. Background technique [0002] With the advent of the "Internet +" era, various Internet services have sprung up like mushrooms. At the same time, the rapid development of new-generation information and communication technologies such as the Internet of Things, cloud computing, big data, and mobile Internet has made Internet information security issues increasingly serious. It has been highlighted that network attacks, illegal intrusions, and hanging horses have shown a trend of rapid growth every year, especially black industry chains such as account hacking and user...

Problems solved by technology

With this method, on the one hand, the attacker can easily determine the encryption method based on the encrypted field information, and crack it by hitting the library; on the other hand, since the sensitive information is stored in a centralized manner, once the database server is If compromised, all user information will be leaked, which is not conducive to the protection of user privacy, and may cause huge economic losses
