A Hybrid Edge-Cloud Architecture for Low-Latency Entitlement Verification in Resource-Constrained Devices

Computer Science > Cryptography and Security [Submitted on 9 Jun 2026] A Hybrid Edge-Cloud Architecture for Low-Latency Entitlement Verification in Resource-Constrained Devices Pravin Nagare, Aditya Sabbineni, Devendra Dahiphale, Faiz Gouri, Pratik Thantharate As digital media consumption shifts toward large-scale Over-the-Top (OTT) platforms, the efficiency of the control plane, specifically entitlement and identity verification, has become a critical factor in user experience. Current architectures often rely on synchronous cloud-tethered validation flows that introduce significant latency, especially on resource-constrained consumer electronics. This paper proposes a Hybrid Edge-Cloud Entitlement Framework designed to minimize user-perceived friction. By implementing a secure, local caching layer within device middleware and utilizing an Adaptive Entitlement Cache with Proactive Refresh (AEC-PR) algorithm, we decouple the user interaction from backend network variability. We evaluate the performance on ARM Cortex-A series hardware, demonstrating that localized cryptographic verification reduces authorization latency from a mean of 422.8ms to 18.4ms (a 95.6% reduction) while mitigating implementation-level side-channel risks through deterministic Ed25519 arithmetic and TEE isolation.
