GaussMark: A key-projected QIM native watermarking method for 3D Gaussian splatting

With the widespread adoption of 3D Gaussian Splatting (3DGS) in digital content creation, copyright protection for 3DGS assets has become increasingly important. Existing 3DGS watermarking methods mostly rely on rendered images for watermark decoding, making them ineffective agai...

Code obfuscation against symbolic execution with mixed Boolean-arithmetic permutation

Code obfuscation is a fundamental technique for software protection and intellectual property defense, yet its effectiveness has been increasingly undermined by advances in symbolic execution and automated deobfuscation. Existing countermeasures based on path explosion, path dive...

A Leakage-Aware Evaluation of a Multi-Scale Attention Temporal Convolutional Network for Binary Network Intrusion Detection

Reliable evaluation is as important as model design in benchmark-based network intrusion detection. This study evaluates a Multi-Scale Attention Temporal Convolutional Network (MS-ATCN) for binary intrusion detection under a leakage-aware and reproducibility-oriented protocol on...

SM2-PRE+: A Lightweight Pairing-Free Proxy Re-Encryption Scheme for Secure IoMT Healthcare Data Sharing

With the rapid development of the Internet of Medical Things (IoMT), wearable sensors and intelligent medical terminals continue to generate a large amount of sensitive medical data, which needs to be uploaded to the cloud platform for storage and sharing. However, IoMT devices u...

Occupational identity, competence dimensions, and psychological well-being among Chinese public security personnel: a cross-sectional path analysis

Police personnel are exposed to substantial occupational stress, yet less is known about how occupational identity and different dimensions of occupational competence are associated with psychological well-being. This study examined the direct associations of occupational cogniti...
