Abstract
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.
An AI-assisted, cross-layer security orchestration framework that integrates epoch-wise telemetry with ML-based risk estimation and formalizes mitigation as a Constrained Markov Decision Process (CMDP), and empirical evidence that adaptive mitigation can reduce security risk without sacrificing service guarantees is provided.

Zonal in-vehicle networks ship Ethernet, MACsec, and TSN, but treat the network itself as trusted: once configured at the factory, there is no standardized runtime way to easily revoke access, rotate keys, or contain a compromised ECU. Zero Trust Architecture targets exactly that gap, yet existing automotive ZTA proposals bolt on dedicated infrastructure that duplicates the SDN management plane already required to enable SDVs. Thus, ZTA is not yet adopted in the automotive domain, and the question remains: can we do better? We answer this in two steps. Step 1 analyses what Open Alliance TC17~v1.0 MACsec/MKA with pre-shared CAKs already provides in terms of NIST SP~800-207 ZTA tenets. Step 2 adds CORECONF/YANG management as proposed in Open Alliance TC19, maps the SDN Controller and Agents one-to-one onto NIST's PE, PA, and PEP. We then instantiate this with two YANG-based mechanisms: a network-access-control flow and a key-management scheme. The result fully covers five and two partially of the seven tenets with no ZTA-specific infrastructure added.
Results show that STGen provides a scalable and reproducible bridge between lightweight protocol emulation and practical deployment-oriented IoT protocol evaluation, and exposes deployment-relevant behavior that controlled emulation alone may hide.
