Generating Realistic and Structured IoT Network Traffic Data with AMC-GAN
The disaggregated Open RAN (O-RAN) architecture requires stringent Service Level Agreements (SLAs) for network slices, particularly for ultra-reliable low-latency communications (URLLC). While Proofs of Retrievability (PoR) can verify data integrity in the O-Cloud, they provide no guarantees on data access latency. In this paper, we introduce Proof of Latency (PoLa), a novel protocol that extends cryptographic PoR audits to enable verifiable latency enforcement in O-RAN. By timing a non-trivial, data-dependent PoR challenge-response, PoLa allows an xApp to verify whether a storage provider can access the required data within a slice-specific latency budget $(\kappa_{d})$. PoLa builds on a lightweight homomorphic PoR construction to achieve a dual guarantee of integrity and performance. Our analysis shows that PoLa incurs minimal and predictable overhead, making it suitable for enforcing latency-sensitive SLAs in O-RAN deployments.
