Abstract:
The Space Information Network (SIN) has evolved from a terrestrial network to an extension, enhancing communication capabilities and enabling augmented intelligence research. However, communication security is crucial due to potential risks like inadequate implementation and high access latency. This could allow malicious organizations to access gateways and compromise the system’s safety and privacy. This work proposes a novel framework and authentication protocol to streamline the incorporation of security measures into unencrypted wireless communication within the SIN. The proposed authentication protocol is based on signcryption and HMAC, ensuring communication confidentiality, access identity validation, and anonymity. The protocol utilizes lattice cryptography and demonstrates resilience against quantum attacks. Besides, the protocol ensures user anonymity while safeguarding identity management by considering a suitable approach to overseeing revocable keys. The evaluated proto
col satisfies message authentication, unlinkability, traceability, and identity privacy criteria, thwarting several security risks, including replay attacks, man-in-the-middle attacks, node impersonation, and quantum attacks. Compared to existing works, our protocol exhibits significant promise in enabling secure communication with adequate functional overheads within the SIN framework.
