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 blockchain, not for distributed networks, so a single user must assign a key to the physical address of each transaction file. See figure 1 , A program-controlled encrypted file storage system for blockchain, including: client, all files will be encrypted in the client; it 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 allows a single user to assign the key to the physical address of each transaction file; the encryption module, the program-controlled encrypted file The storage system mounts a virtual transaction file system to a standard Unix and Linux file system; it also includes a daemon process, which is loaded on the client computer to convert the standard program-controlled en...

Abstract

The present invention provides a block chain program-controlled encrypted file storage system, including: (1) a client, where all files are encrypted; (2) mount points in Unix and Linix systems, used to cover up transactions The specific operation details of the file; (3) a key distribution module, so that a single user can distribute a key for each transaction file physical address; (4) an encryption module, used for the program-controlled encrypted file storage system to convert a virtual transaction file system Mounted on a standard Unix and Linix file system; (5) daemon process, the daemon process is loaded on the client, and is used to convert the standard program-controlled encrypted file storage system call into a special program-controlled encrypted file storage system call. The blockchain program-controlled encrypted file storage system and its method are several times faster than ordinary encrypted file storage systems when reading and writing large files and creating small files.

Description

Technical field [0001] The invention relates to the transaction data security problem of the block chain, in particular to a program-controlled encrypted file storage system of the block chain and a method thereof. Background technique [0002] The emergence of Bitcoin in 2009 brought about a disruptive result-blockchain technology. The blockchain is a secure account book database composed of data blocks. Users can continuously update and upgrade here. For financial institutions, blockchain can speed up transaction processing, reduce costs, reduce middlemen, improve market insights, and increase business transparency. [0003] Computing and storage are the two basic tasks of a computer system. With the explosive growth of information, storage components will experience direct storage based on a single server, to cluster grid storage based on local area networks, and finally to a data grid based on WAN. Blockchain technology is the end of current development. The intrinsic characte...
