Blockchain-based intelligent data rapid encryption transmission system

Abstract

The invention discloses a blockchain-based intelligent data rapid encryption transmission system, which comprises a user identity authentication module, a blockchain, a library collection data entry module, a book borrowing information input module, a data encryption module, a book borrowing information classification statistics module, a key sharing module and a data transmission module; key design distribution is carried out on library book resources and user information through the key distribution unit, the current situation that key distribution of a symmetric encryption algorithm is easy to steal and key transmission is not safe is improved, and the security of key distribution is improved by improving the difficulty of calculating discrete logarithms in a finite field; books of the same type borrowed by a user at the same time are counted in the book borrowing information input module, public keys of the books are sent to the corresponding users in a unified mode, secret keys of the same kind of books are designed through the key distribution unit, and the keys are sorted and then sent to the users in a unified mode. Users on the nodes can also transmit data to each other through the blockchain technology, and the data transmission rate is improved.

Description

technical field

[0001] The invention relates to the technical field of block chains, in particular to a block chain-based intelligent data fast encrypted transmission system. Background technique

[0002] Data encryption refers to converting plaintext into ciphertext through encryption algorithms and encryption keys. It is the most reliable way to protect information. It can realize the function of information concealment and protect information security. Data transmission encryption technology The purpose of this method is to encrypt the data flow in transmission and prevent data loss in the storage link. Data encryption technology includes symmetric encryption, but symmetric encryption has the disadvantages of being stolen during the key transfer process and having risks. How to design encryption Keys and rational distribution are crucial. The foundation of the digital construction of university libraries is to digitize high-quality collections. The promotion and applicati...
