Problems solved by technology

[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

Embodiment

[0020] The program-controlled encrypted file storage system is designed for local use of the blockchain, not for a distributed network, so individual users must assign keys to each transaction file physical address. see figure 1 , a program-controlled encrypted file storage system for blockchain, including: client, all files will be placed in the client after encryption; also includes mount points in Unix and Linix systems, use this mount point To cover up the specific calculation details of the transaction file, so that the transaction file to be encrypted is the same as other transaction files; the key distribution module enables a single user to assign a key to the physical address of each transaction file; the encryption module, the program-controlled encrypted file The storage system mounts a virtual transactional file system onto a standard Unix and Linux file system; also includes a daemon process that is loaded on the client machine to translate standard program-contro...

Abstract

The invention provides a program-controlled encrypted file storage system for a block chain. The program-controlled encrypted file storage system comprises: (1) a client, in which all files are added after being encrypted; (2) mounting points in Unix and Linix systems, which are used for covering up concrete operation details of transaction files; (3) a secret key distribution module for enabling a single user to distribute a secret key to each physical address of each transaction file; (4) an encryption module which is used for the program-controlled encrypted file storage system to mount one virtual transaction file system onto one standard Unix and Linix file systems; (5) a daemon process which is loaded to the client and used for converting a standard program-controlled encrypted file storage system call into a special program-controlled encrypted file storage system call. According to the program-controlled encrypted file storage system for the block chain and a method thereof, processing speeds when big files are read and written and small files are created are higher than those of a common encryption file storage system by over multiple times.

Description

technical field [0001] The invention relates to the transaction data security problem of the blockchain, in particular to a program-controlled encrypted file storage system of the blockchain and a 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 i...
