AI Technical Summary

Technical Problem

Existing router systems are at risk of data breaches when facing complex network attacks. They lack effective data integrity and tamper-proof verification mechanisms, making it difficult to ensure data integrity and authenticity.

Method used

The method employs a hierarchical hash chain, hash-public key binding encryption, and smart contract event storage. Ciphertext is generated through AES encryption, hash calculations and RSA-OAEP encryption are performed, and blockchain evidence storage is used to ensure the integrity and immutability of the data.

Benefits of technology

It enables efficient deployment of blockchain anti-tampering functionality on resource-constrained embedded devices, reducing the consumption of computing resources and storage space, ensuring data integrity and authenticity, quickly detecting tampering and triggering alarms, and reducing potential losses.

Abstract

This invention discloses a method, system, and device for preventing router data tampering, relating to the field of computer network technology. The method includes: encrypting received raw data to generate ciphertext; performing hierarchical hashing on the ciphertext, generating a first-level hash value and then combining it with a user identifier and a timestamp to generate a second-level hash value; encrypting the second-level hash value to obtain an encrypted hash value; constructing transaction data containing a user identifier, the first-level hash value, the encrypted hash value, a timestamp, and a router certificate identifier; signing the transaction data and submitting it to a blockchain network for notarization; obtaining a unique transaction hash value returned by the blockchain network; and storing the transaction hash value, initialization vector, key handle corresponding to the AES key, and ciphertext length information in the router's local non-volatile memory. This method, combining hierarchical hashing with the design of only uploading encrypted hashes to the blockchain, achieves efficient and highly secure proactive tampering prevention on resource-constrained routers.
