A post-quantum cryptographic communication device for a satellite constellation communication network

By constructing a post-quantum cryptographic encryption communication device for a satellite constellation communication network, the constellation topology and link status are perceived in real time, and key negotiation is dynamically triggered. This solves the security and reliability problems of satellite communication systems under the threat of quantum computing and achieves post-quantum security protection across the entire link.

AI Technical Summary

Technical Problem

Existing satellite communication systems lack long-term security in the face of quantum computing threats, and lack dynamic key negotiation and authentication mechanisms, making them unable to adapt to changes in constellation topology and link status, resulting in reduced communication security and reliability.

Method used

By employing a constellation link management module, a post-quantum identity authentication module, a post-quantum key negotiation module, a data encryption processing module, a secure key storage module, and a hardware acceleration and power consumption control module, a secure communication mechanism resistant to quantum attacks is constructed. This mechanism can perceive the constellation topology and link status in real time, dynamically trigger the key negotiation process, and provide post-quantum secure key materials and identity verification.

Benefits of technology

It improves the long-term security and resistance to physical attacks of satellite communication systems, adapts to dynamic topology environments, and enhances the efficiency of key negotiation and the reliability of communication.
