Secure Data Transmission and Intelligent Swarm Management for Inactive Satellites in WAICS Networks

The rapid growth in satellite numbers has exacerbated challenges posed by inactive satellites (IAS), which remain in orbit without security updates, leaving them vulnerable to exploitation. These vulnerabilities pose risks to information security and space network stability, necessitating continuous yet resource-efficient management. Given the limited resources of IAS, traditional methods are insufficient. This study proposes a protocol leveraging Proxy Re-Encryption (PRE) technology for secure data exchange between IAS and external devices. A resource-rich Swarm Controller Node (SCN) manages intra-swarm communication and dynamically transitions roles to newly joining IAS with higher resources, enhancing scalability and network continuity. The design reduces communication distances, improves data exchange efficiency, and integrates Wireless Artificial Intelligent Computing Systems (WAICS) principles to optimize network topology. The SCN serves as an intermediary, re-encrypting data to ensure confidentiality and integrity without exposing sensitive information. Security analysis confirms resistance to chosen plaintext and ciphertext attacks (CPA/CCA), ensuring data remains inaccessible to the SCN while fully decryptable by the intended recipient. Additionally, the protocol minimizes power consumption for resource-constrained IAS and ensures stable operation across orbital environments. By incorporating intelligent data processing, the proposed network enhances communication efficiency and resilience, addressing critical challenges in managing inactive satellites.
