Placement-Specific Sufficient QKD Block Sizes for Hybrid QKD–ML-KEM Systems: Finite-Key Planning and Split-Security Provisioning

Hybrid quantum key distribution (QKD) and post-quantum cryptography (PQC) systems are often described as layered security architectures, yet deployments face a basic provisioning question: how many QKD bits are needed, and where should they enter an ML-KEM-based system? This article develops a placement-aware framework...

GCTMR: Graph Contrastive Transformer for Multibehavior Recommendation

GCTMR (Graph Contrastive Transformer for Multibehavior Recommendation), a framework that integrates graph-based contrastive learning with a behavior-aware Transformer architecture, is proposed, with particularly remarkable performance under sparse data conditions where traditional methods struggle most.
