Dynaseal: A Backend-Controlled LLM API Key Distribution Scheme with Constrained Invocation Parameters

Due to the exceptional performance of Large Language Models (LLMs) in diverse downstream tasks,there has been an exponential growth in edge-device requests to cloud-based models.However, the current authentication mechanism using static Bearer Tokens in request headersfails to provide the flexibility and backend control required for edge-device deployments.To address these limitations, we propose Dynaseal,a novel methodology that enables fine-grained backend constraints on model invocations.
