Title:
READ-ONLY SECURITY FILE STORAGE SYSTEM FOR BLOCK CHAIN, AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/032377
Kind Code:
A1
Abstract:
A read-only security file storage system for a block chain, comprising: (1) a user-server authentication protocol module, used for executing a mutual authentication protocol between a user and a server by means of 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; (6) a client, a conventional path being converted into data and a digital signature being made in a client environment, then the data being distributed to an arbitrary number of running servers, and the daemon receiving a request from the client and returning the data; and (7) a stamp protocol module, used for detecting the integrity of transaction data. By means of the storage system and the method thereof, the system storage time of a large file is shortened, and a creator can complete a cryptographic operation, data creation, and ciphertext-based decryption in an environment without a network.
