Encryption storage system for block chains and method for applying encryption storage system

Abstract

The invention provides an encryption storage system for block chains. The encryption storage system comprises file groups (S) (1), open file systems (2) and lock box devices (3). The file groups (S) are used for reducing the amounts of secret key exchange between users, differentiating file reading and writing, effectively processing and revoking access rights of the users and allowing authorization files of a distrusted server to carry out write operation; the open file systems are used for embedding encryption storage system prototypes of the block chains and comprise authentication databases; the lock box devices comprise a plurality of secrete key distribution schemes, and safety strategies and authentication mechanisms can be customized for files of each user by the aid of one of multiple client-based secret key distribution schemes. The invention further discloses a method for applying the encryption storage system for the block chains. The encryption storage system and the method have the advantages that the problem of possibly insufficient capacity of server sides due to expensive cipher computation can be solved by the aid of the encryption storage system and the method; the files can be accessed when file owners are offline, and accordingly the trouble of the requirement on contact with the corresponding file owner when each file needs to be accessed can be prevented.

Description

technical field [0001] The invention relates to the transaction data security problem of the block chain, in particular to an encrypted storage system of the block chain and a use method thereof. Background technique [0002] The emergence of Bitcoin in 2009 brought a subversive result - block chain technology, block chain is a secure ledger database, composed of data blocks, users can continuously update and upgrade For financial institutions, blockchain can speed up transaction processing, reduce costs, reduce middlemen, improve market insight, and increase business transparency. [0003] Computing and storage are the two basic tasks of computer systems. With the explosive growth of information, storage components will experience direct-connected storage based on a single server, cluster grid storage based on a LAN, and finally develop into a data grid based on a wide area network. Blockchain technology is at the very end of the current development. The intrinsic characte...

[0003] Computing and storage are the two basic tasks of computer systems. With the explosive growth of information, storage components will experience direct-connected storage based on a single server, cluster grid storage based on a LAN, and finally develop into a data grid based on a wide area network. Blockchain technology is at the very end of the current development. The intrinsic characteristics of this data storage medium include intelligent storage, storage service quality can guarantee service differentiation and performance guarantee for user applications, storage is object-oriented mass storage, and Network storage must be guaranteed to be confidential, complete and secure. The existing Internet does not have a good or convenient way to ensure the confidentiality, integrity, availability, and Non-repudiation and the reliable performance of the entire network storage system, especially the emergence of blockchain trusted computing technology in recent years, put forward higher requirements for network storage security
