When it comes to cloud applications, authentication systems are a captive audience of increasingly applicable attacks that steal credentials and vulnerable authentication methods, as well as vulnerable applications that will soon be disrupted by a new problem: quantum computing. Mathematical algorithms such as RSA and Elliptic Curve Cryptography (ECC) algorithms are vulnerable to Shor's algorithm and behavioral solutions do not sufficiently provide the provable security to a regulated cloud environment. The proposed framework, QBAC, is a Quantum-Resistant Behavioral Authentication Framework which combines post-quantum key encapsulation (CRYSTALS-Kyber) with multi-modal behavioral biometric verification and session monitoring in real-time. All these characteristics are combined within a framework that synergizes keystroke, mouse, timing and regularity and feeds a machine-learning based classification model designed to calculate a real-time Authentication Confidence Score (ACS). A Continuous Trust Score (CTS) is being kept in each cloud session that allows for anomaly-based re-authentication before hijack can become successful. Experimental results show that QA performs authentication accurately with 98.4%, False Acceptance Rate is 1.2%, False Rejection Rate is 0.8% and the Quantum Security Strength (QSS) score is 96, outperforming bases of RSA and ECC at all attack complexities and more than traditional Multi-Factor Authentication accuracy, outlier, reject rates and security strengths.

Scientific documentation is growing so rapidly that it poses a daunting challenge for scientists to find new applications, new domain links and new fields of study. Even with keyword-based search tools, conventional literature review approaches are inadequate for scaling up to cover large volumes of research and systematically reveal research gaps or grounded hypotheses. This paper introduces AgentSci, a novel multi-agent framework that combines the functionalities of Large Language Models (LLMs), Knowledge Graph Reasoning (KGR) and co-operative multi-agent models to enable automatic scientific discovery pipeline. AgentSci consists of five specialised agents which collaboratively process a corpus of research papers to derive ranked, actionable and novel research hypotheses: Literature Mining Agent, Knowledge Graph Builder, Gap Discovery Agent, Hypothesis Generation Agent and a Validation Agent. To measure the quality and usefulness of the outputs generated, we introduce a composite scoring model that combines five different scores: Knowledge Relevance Score (KRS), Research Gap Score (RGS), Hypothesis Novelty Index (HNI), Agent Consensus Score (ACS), and Scientific Discovery Potential (SDP). The accuracy in gap detection, novelty of hypothesis, and relevance of the research are significantly improved by AgentSci over the conventional retrieval based systems in four scientific research areas demonstrated through experiments. AgentSci is a step towards fully automatic scientific discovery, brought by AI.
