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 pr...

A novel methodology which leverages Maximum Satisfiability Modulo Theories (MaxSMT) to automatically compute a formally correct and optimized allocation scheme and configuration of SDN switches by refining security policies, user-defined or derived from detected attacks is proposed.

This thesis investigates how CoAP can be extended to support secure one-to-many multicast notifications, where a single notification reaches all observing clients, secured end-to-end using Group OSCORE, and validates the security properties of the proposed solution against a defined attack model.
This work 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, and instantiates two YANG-based mechanisms: a network-access-control flow and a key-management scheme.
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.
