Data security storage and security sharing system based on distributed key parameter fragments

Abstract

The invention discloses a data security storage and security sharing system based on distributed key parameter fragments. The data security storage and security sharing system comprises the following steps: initializing and updating a key parameter queue by a client through a virtual gateway server and a key parameter fragment server; after the key parameter queue is updated, encrypting the data according to an encryption rule and storing the data in a data storage server; and obtaining the encrypted data by the client through the virtual gateway server and the key parameter fragment server again, and decrypting the encrypted data according to the password rule to obtain the original data for service requirements. According to the method, the distributed server cluster is adopted to perform data encryption and storage, and the regularly updated key parameter queue is matched with the custom password rule combination to symmetrically encrypt the key, so that the speed is high, the key is regularly changed. The virtual gateway server, the key parameter fragment server cluster and the storage server are all attacked. All the data cannot be decrypted, so that the security of the data is ensured.

Description

technical field [0001] The invention relates to the field of information security, in particular to a data security storage and security sharing system based on distributed key parameter fragments. Background technique [0002] In recent years, with the vigorous development of the Internet, a large amount of information and data will be generated in the use of the network. Among these information and data, many of them need to be stored safely, such as medical information and financial information. We generally use symmetric encryption or asymmetric encryption to encrypt and store data to ensure data security. [0003] However, this fixed-key encryption method has relatively prominent shortcomings. Once the key is cracked, all information can be decrypted and obtained. Secondly, in the asymmetric encryption method, due to the complexity of the encryption algorithm, the speed of encryption and decryption Slow and not suitable for large amounts of data encryption. All kinds ...

[0003] However, this fixed-key encryption method has relatively prominent shortcomings. Once the key is cracked, all information can be decrypted and obtained. Secondly, in the asymmetric encryption method, due to the complexity of the encryption algorithm, the speed of encryption and decryption Slow, not suitable for large amounts of data encryption

Various drawbacks lead to fixed key encryption can no longer meet the current security needs
