NiIas: Non-Interactive Instant Authentication and Secure Data Delivery Protocol for Multi-Access Edge Computing

The inherent heterogeneity and mobility of Multi access Edge Computing (MEC) necessitate security protocols that ensure instant connectivity while maintaining resilience against resource exhaustion. This paper presents NiIas, a non-interactive instant authentication and secure data delivery proto col. Unlike conventional protocols that require prior handshakes, NiIas enables immediate payload transmission without session resumption delays. The protocol leverages a multi-authorization identity-based cryptosystem to decentralize trust and eliminate certificate management overhead. Furthermore, NiIas employs an authenticate-before-decryption mechanism as a lightweight admission control. This design filters unauthorized traffic prior to decryption and effectively protects edge verifiers from denial of-service attacks. Rigorous security analysis formally establishes the protocol's cryptographic guarantees. Moreover, numerical simulations on resource-constrained devices and M/D/1 queuing theoretic analysis demonstrate that NiIas achieves superior availability and stability compared to state-of-the-art protocols. © 2004-2012 IEEE.
