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

[0022] In a distributed environment, for read-only data, the read-only secure file storage system provides high availability based on self-certifying pathnames without the need for server-side cryptographic calculations, provides better performance, and produces multiple copies of read-only files It can ensure the integrity of the data at the same time, without degrading the security level like traditional replication.

[0023] see figure 1 , a read-only secure file storage system for blockchains, including a user-server authentication protocol module for performing a mutual authentication protocol between a user and a server through a self-certifying pathname that has the The public key of a file inside, the creator of the file has the right to distribute the key, thus providing a wider range of cryptographic choices.

[0024] It also includes a signature and encryption module. In order to correctly encrypt transaction files, the administrator converts the content in the tra...

Abstract

The invention provides a read-only security file storage system for a block chain. The system comprises: (1) a user server authentication protocol module used for executing a mutual authentication protocol between a user and a server via a self-certified path name; (2) a signature and encryption module used for correctly encrypting a transaction file; (3) a transaction file access verification module used for verifying the trustworthiness of the user; (4) a security file data generator; (5) a daemon of a read-only security file data server; and (6) a client, wherein a traditional path is converted into data and digital signature is carried out in a client environment, then the data is distributed to an arbitrary number of running servers, and the daemon receives the request of the client and returns the data; and (7) a postmark protocol module used for detecting the integrity of transaction data. By adoption of the storage system and the method provided by the invention, the storage time of a large file system is shortened, and a creator can complete cryptographic operation, data creation and decryption according to ciphertext in an environment without a network.

Description

technical field [0001] The invention relates to the transaction data security problem of the block chain, in particular to a read-only secure file storage system of the block chain 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 intrinsic c...
