Chaotic Map-Based Authentication and Key Agreement Protocol with Low-Latency for Metasystem

With the rapid advancement in exploring perceptual interactions and digital twins, metaverse technology has emerged to transcend the constraints of space-time and reality, facilitating remote AI-based collaboration. In this dynamic metasystem environment, frequent information exchanges necessitate robust security measures, with Authentication and Key Agreement (AKA) serving as the primary line of defense to ensure communication security. However, traditional AKA protocols fall short in meeting the low-latency requirements essential for synchronous interactions within the metaverse. To address this challenge and enable nearly latency-free interactions, a novel low-latency AKA protocol based on chaotic maps is proposed. This protocol not only ensures mutual authentication of entities within the metasystem but also generates secure session keys. The security of these session keys is rigorously validated through formal proofs, formal verification, and informal proofs. When confronted with the Dolev-Yao (DY) threat model, the session keys are formally demonstrated to be secure under the Real-or-Random (ROR) model. The proposed protocol is further validated through simulations conducted using VMware workstation compiled in HLPSL language and C language. The simulation results affirm the protocol’s effectiveness in resisting well-known attacks while achieving the desired low latency for optimal metaverse interactions.
