OTel: Open Telco AI Datasets, Benchmarks, and Models
Farbod Tavakkoli, Gregory Diamos, Kenneth Church +19
We present Open Telco (OTel), an open telecom AI resource that releases derived telecom datasets for retrieval, reranking, instruction tuning, and safety/abstention, together with…
Tick-Tock on the Open Fronthaul: Securing Synchronization in O-RAN
Yiwei Zhang, Enrico Pisanti, Imtiaz Karim +2
The Precision Time Protocol (PTP) provides the time and phase synchronization required by disaggregated Open Radio Access Networks (O-RAN). Yet, in current open fronthaul deploymen…
Understanding the Usability of Cryptographic Verification Tools
Tarikul Islam, Yasin Islam, Khandakar Ashrafi Akbar +1
Cryptographic protocol verification tools are widely used to analyze the security of complex protocols, yet how users interact with these tools remains comparatively understudied.…
A2ABreak: Systematic Security Analysis of the A2A Protocol
Alireza Lotfi, Mirza Masfiqur Rahman, Imtiaz Karim +1
The Agent2Agent (A2A) protocol, now governed by the Linux Foundation, is an open standard that enables autonomous AI agents to discover, authenticate with, and delegate tasks to on…
PhantomCall: Evading ML Malware Detectors via Function Call Graph Perturbation
Md Ajwad Akil, Adrian Shuai Li, Imtiaz Karim +3
Prior adversarial attacks on Windows PE malware detectors target raw bytes, PE headers, or intra-function control-flow graphs, leaving the function call graph (FCG) unexplored as a…
OTel: Building Domain-Specialized Telecom LLM Foundations for Intelligent Networks
Farbod Tavakkoli, Roderic Paulk, Jorden Terrazas +9
Frontier AI models have advanced rapidly, but they still struggle with telecom-specific tasks. We present Open Telco (OTel), an open telecom AI resource with derived datasets for r…
Securing Agentic AI: From Per-Action Checks to Trajectory Assurance
Alireza Lotfi, Subangkar Karmaker Shanto, Imtiaz Karim +1
Autonomous agents are increasingly used to execute consequential tasks in environments governed by operational constraints, organizational policies, regulatory requirements, and te…
A Lightweight Post-Quantum Authentication Framework for 5G Base Station Bootstrapping
Saleh Darzi, Mirza Masfiqur Rahman, Imtiaz Karim +3
The absence of authenticated bootstrapping between User Equipments (UEs) and Base Stations (BSs) in 5G leaves System Information Block (SIB) broadcasts unprotected, enabling fake B…
Tracing Users' Privacy Concerns Across the Lifecycle of a Romantic AI Companion
Kazi Ababil Azam, Imtiaz Karim, Dipto Das
Romantic AI chatbots have quickly attracted users, but their emotional use raises concerns about privacy and safety. As people turn to these systems for intimacy, comfort, and emot…
Breaking 5G on The Lower Layer
Subangkar Karmaker Shanto, Imtiaz Karim, Elisa Bertino
As 3GPP systems have strengthened security at the upper layers of the cellular stack, plaintext PHY and MAC layers have remained relatively understudied, though interest in them is…
