Enhancing RD-BIBD Key Pre-distribution with Permutation Aware Node Assignment in Fog Computing

This paper proposes a secure, hierarchical key pre-distribution scheme for fog-assisted IoT networks that enhances resilience against physical node capture attacks by integrating Residual Design-based combinatorial structures with a randomized permutation mechanism to obscure the deterministic mapping between cryptographic blocks and physical nodes, all while maintaining low overhead and high connectivity.

Multi model deliberation improves the stability of automated scoring by large language models across genres and assessment contexts

This study demonstrates that a multi-model deliberation framework, where three heterogeneous Chinese large language models iteratively exchange scores and rationales, significantly improves the stability and precision of automated essay scoring across diverse genres and assessment contexts, with any resulting systematic bias being effectively correctable through standard human-anchored calibration.
