AI Technical Summary

Technical Problem

In existing digital identity management systems, the separation of digital identity from network address leads to complex identity authentication, high risk of user privacy leakage, and the cryptographic system is prone to collapse under the threat of quantum computing. Furthermore, the lack of heterogeneous integration mechanisms and adaptive privacy protection makes it difficult to achieve smooth migration.

Method used

By employing quantum-safe chips and the quantum chain distributed ledger network, combined with a dynamic verifiable obfuscated address derivation algorithm, a heterogeneous cryptographic system fusion signature algorithm, a quantum-resistant adaptive threshold consensus algorithm, and a distributed adaptive noise modulation algorithm, the cryptographic binding of quantum digital identifiers with IPv6 addresses is realized, supporting threshold verification and adaptive privacy protection. It also incorporates temporal convolutional networks for behavior prediction and subject association.

Benefits of technology

It achieves non-linkable derivation of quantum digital identifiers and IPv6 addresses, enhancing robustness against quantum attacks and privacy protection capabilities, ensuring user privacy and security, supporting smooth password migration and automated legal liability tracing for entities, and maintaining high system availability.

Abstract

The invention discloses a digital identity management operation system based on a quantum chain. The digital identity management operation system comprises a quantum security chip and a quantum chain distributed account book network, the quantum chain distributed account book network is used for recording a mapping relationship between a quantum digital identifier and a post quantum public key of a subject, a digital identity identifier, a subject information abstract and a network layer address prefix, and providing a decentralized analysis service; the quantum security chip comprises a multi-source authentication data storage partition used for storing a subject information abstract authenticated by at least one authentication mechanism; the post quantum cryptography engine is used for generating and storing post quantum public and private key pairs so as to execute post quantum signature and verification; and the address deriving unit is used for generating a network layer address according to the quantum digital identifier and the post-quantum public key. According to the invention, cryptographic binding and non-linkable derivation of the quantum digital identifier and the IPv6 address are realized, so that the same identifier generates network addresses which cannot be associated in different time periods.
