Patent Granted for Blockchain-Based Secure Communication Data Transmission System

On November 28, 2024, the State Intellectual Property Office of China announced that China Post Telecom Construction Consulting Co., Ltd. (Zhongyou Tong Jian She Zi Xun You Xian Gong Si) successfully obtained a patent for a "Blockchain-Based Secure Communication Data Transmission System," with publication number CN119030774A and an application date of August 2024. The core of this patented technology lies in enhancing the security of communication data transmission. Its innovation stems from the ingenious combination of blockchain technology and multiple cryptographic algorithms, creating a robust defense against data breaches.

This patent describes a novel communication data security transmission system designed to address existing security vulnerabilities in traditional data transmission, such as key leakage, insufficient encryption strength, and man-in-the-middle attacks. The system architecture consists of four key modules: a Key Randomness Assessment Module, an Encryption Strength Prediction Module, a Key Encryption Level Classification Module, and a Key Complexity Enhancement Module. These modules work together to form a multi-layered security protection system, effectively ensuring the integrity and confidentiality of communication data.

Firstly, the Key Randomness Assessment Module forms the foundation of the entire system. It rigorously assesses the randomness of keys generated during data encryption. Key randomness is directly related to data security; a non-random key is easily cracked, leading to data leakage. This module uses advanced algorithms to comprehensively analyze generated keys, determining their randomness level and classifying them as either high-randomness or low-randomness. Only keys meeting the high-randomness standard are used for data encryption, ensuring data security.

For keys assessed as low-randomness, the system activates the Encryption Strength Prediction Module. This module utilizes a machine learning model to analyze the hash characteristics of the key and predict its encryption strength. The machine learning model accurately assesses key security and predicts its resistance to various attacks based on extensive historical data and cryptographic principles. If the prediction indicates insufficient encryption strength, the system automatically activates the Key Complexity Enhancement Module.

The Key Complexity Enhancement Module is a crucial part of the system's security protection. It employs key derivation functions, combined with iterative hashing algorithms and random salts, to enhance low-randomness keys, increasing their complexity to meet security standards. Iterative hashing performs multiple hash operations on the key, increasing its irreversibility, while random salts further enhance key randomness, effectively preventing brute-force and dictionary attacks. These measures ensure that processed keys meet security requirements, effectively protecting communication data.

The systems design philosophy centers on multi-layered security protection, ensuring that the failure of any single component does not compromise the entire system. Each module incorporates security monitoring mechanisms to detect and address potential vulnerabilities. For example, the system immediately alerts administrators of any detected anomalies or security risks, allowing for prompt mitigation.

Importantly, this patented technology leverages the advantages of blockchain technology. Blockchain's decentralized, immutable, and transparent nature provides enhanced security for key management and storage. Storing keys on the blockchain prevents single-point attacks and tampering, improving overall system security and reliability.

In conclusion, China Post Telecom Construction Consulting Co., Ltd.'s patented "Blockchain-Based Secure Communication Data Transmission System" represents a significant breakthrough in secure communication data transmission technology. By cleverly combining blockchain technology and multiple cryptographic algorithms, it creates a multi-layered security protection system, effectively addressing vulnerabilities in traditional communication data transmission and providing strong technical support for ensuring data security. The application of this technology will significantly enhance the security of various communication systems, providing users with a more secure and reliable communication environment. The successful application of this patent also demonstrates the strengthening of China's technological capabilities in the field of communication security, contributing positively to the development of the country's information security industry. This technology is expected to be widely applied in various fields in the near future, contributing to the construction of a more secure and reliable digital society. The innovation lies in the multi-layered security protection mechanism and the effective use of blockchain technology, making the system more secure and reliable, while providing new ideas and directions for future communication security technology development. Through rigorous key assessment, prediction, and enhancement, the system effectively reduces the risk of data leakage and improves communication data security. Its efficient algorithms and robust security protection capabilities will provide strong security guarantees for various application scenarios.
