Chainwash: Multi-Step Rewriting Attacks on Diffusion Language Model Watermarks
Mohd Ruhul Ameen, Akif Islam, Nadim Mahmud +1
Statistical watermarking is a common approach for verifying whether text was written by a language model. Most existing schemes assume autoregressive generation, where tokens are p…
QASecClaw: A Multi-Agent LLM Approach for False Positive Reduction in Static Application Security Testing
Mohd Ruhul Ameen, Md Takrim Ul Alam, Akif Islam
Static Application Security Testing tools help developers find security vulnerabilities before release, but they often produce many false positives. This increases manual review ef…
Empirical Evidence of Complexity-Induced Limits in Large Language Models on Finite Discrete State-Space Problems with Explicit Validity Constraints
Md. Fahad Ullah Utsho, Mohd. Ruhul Ameen, Akif Islam +2
Large Language Models (LLMs) are increasingly described as possessing strong reasoning capabilities, supported by high performance on mathematical, logical, and planning benchmarks…
Beyond Ray-Casting: Evaluating Controller, Free-Hand, and Virtual-Touch Modalities for Immersive Text Entry
Md. Tanvir Hossain, Mohd Ruhul Ameen, Akif Islam +5
Efficient text entry remains a primary bottleneck preventing Virtual Reality (VR) from evolving into a viable productivity platform. To address this, we conducted an empirical comp…
Prompt Control-Flow Integrity: A Priority-Aware Runtime Defense Against Prompt Injection in LLM Systems
Md Takrim Ul Alam, Akif Islam, Mohd Ruhul Ameen +2
Large language models (LLMs) deployed behind APIs and retrieval-augmented generation (RAG) stacks are vulnerable to prompt injection attacks that may override system policies, subv…
Critical Thinking in the Age of Artificial Intelligence: A Survey-Based Study with Machine Learning Insights
M Murshidul Bari, Akif Islam, Mohd Ruhul Ameen +2
The growing use of artificial intelligence (AI) in education, professional work, and everyday problem-solving has raised important questions about its effect on human reasoning. Wh…
