Embodiment Construction

[0077] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention. Obviously, the embodiments described below are only It is a part of the embodiments of the invention, but not all of them. Based on the embodiments of the invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the invention.

[0078] figure 1 It is a flow chart of an encryption method supporting big data provided by an embodiment of the present invention.

[0079] In step 101, an encryption framework based on digital envelopes and digital signatures is established.

[0080] The so-called digital envelope technology means that the plaintext data is first encrypted by a symmetric encryption algorithm, and...

Abstract

The invention provides a parallel encryption method and decryption method supporting big data. The invention integrates symmetric key encryption and public key encryption organically, and constructs aparallel encryption framework by using digital envelope technology and digital signature technology, so that the confidentiality, the integrity and the non-repudiation of data are guaranteed. Aimingat big data, especially large files, a multithreaded parallel processing method is adopted, which splits a document to be encrypted into several data blocks and encrypts the data blocks separately. Areceiving party does not have to wait for the completion of transmission of the entire document before decryption, verification or even request for retransmission, and only needs to verify whether thereceived data blocks are correct, so that the efficiency of the entire transmission process is improved. On the other hand, blockwise transmission of the documents also ensures the security to a certain extent. Therefore, application requirements of safe data transmission under the background of big data can be met.

Description

technical field [0001] The present invention relates to the field of information security in computer technology, more specifically, the present invention relates to a parallel encryption method and decryption method supporting large data. Background technique [0002] The rapid development of information technology has led to the rapid development of network-based applications such as mobile Internet, cloud computing, and blockchain, making the amount of data transmitted on the network increasing. Many of these network applications involve data security and privacy protection, such as e-commerce, e-government, finance, electricity, personal privacy, etc., for which data transmission needs to be encrypted. Data encryption is a time-consuming application. In order to improve data transmission efficiency under the background of big data, parallel encryption needs to be adopted. The present invention provides a parallel encryption method under the background of big data and its...
