A Hierarchical Verifiable Query System Based on Selective Leakage

Abstract

The invention belongs to the technical field of passwords, in particular to a selective leak-based hierarchical verifiable query system. The system of the present invention includes a storage module, a user module, and a verification module; the storage module is responsible for storing and processing data; the storage module stores the fields stored in the database in a selectively leaked Huffman tree, and mixes them in different orders at different nodes of the tree Use four 256-bit encryption functions to encrypt information; the user module is responsible for receiving and processing user operations; users register and log in to the system on the browser side, and use the SM2 national secret algorithm to encrypt personal information; the verification module is equivalent to a validator, using To verify whether the field stored in the storage module has been tampered with. The system of the present invention enables users to check the obtained data at the client end, reduces the risk of web page content being tampered with, greatly reduces the operating frequency of anti-tampering mechanisms such as core embedded technology, and reduces enterprise expenses while ensuring the correct rate.

Description

technical field [0001] The invention belongs to the technical field of cryptography, in particular to a hierarchical verifiable query system based on selective leakage. Background technique [0002] The 21st century is an era of rapid development of the Internet. According to a report released by the United Nations Broadband Commission for Sustainable Development, by the end of 2015, about 3.2 billion people in the world had used the Internet, and by the end of 2016, this number could reach 3.5 billion. The Internet has penetrated all walks of life, and is gradually changing the way people live and work, and has also brought new business models and opportunities to various industries. However, due to the immature market environment and regulatory mechanisms, various networks have also become Crimes emerge in an endless stream, posing a huge threat to Internet security. [0003] As one of the oldest and most important information distribution and access methods in the Intern...

Problems solved by technology

After the content of the website is tampered with, it will cause the public to question the information security protection capabilities of government enterprises and damage their credible image;

[0006] (2) Influence information transmission

For the query system, if the returned data is tampered with, it will affect all aspects of all walks of life: the financial system may cause huge losses, scientific research institutions may cause experiments to fail, and government, schools and other official institutions may suffer losses. Credibility affects social harmony and stability

Existing anti-tampering systems for web pages require a large number of dynamic scans, which is extremely expensive
