Special Issue Information

Dear Colleagues,

In today's data-driven world, the exponential growth of digital information and the rapid adoption of emerging technologies such as cloud computing, the Internet of Things (IoT), and artificial intelligence have brought unprecedented opportunities—and significant security challenges. Ensuring data security has become a critical concern for researchers, practitioners, and policymakers across a wide range of domains, from finance and healthcare to government and industrial systems.

This Special Issue aims to provide a comprehensive forum for the latest research and developments in data security. We invite original contributions that address fundamental challenges, propose innovative technologies, or demonstrate practical applications for securing data across diverse platforms and environments. Topics of interest include, but are not limited to, the following:

  • Data encryption and secure computation;
  • Privacy-preserving machine learning;
  • Blockchain and distributed ledger technologies for data security;
  • Intrusion detection and anomaly detection in large-scale systems;
  • Secure data sharing and access control;
  • Security in edge and cloud computing environments;
  • Cyber–physical systems and IoT data protection;
  • Formal methods and verification for data security;
  • Adversarial attacks and defenses in data-driven models;
  • Real-world case studies and applications in critical sectors.

By bringing together interdisciplinary perspectives, this Special Issue seeks to foster a deeper understanding of data security challenges and promote the development of robust, scalable, and practical security solutions for the future.

In supervised fine-tuning (SFT) for Text2SQL tasks, particularly for databases with numerous tables, encoding schema features requires excessive tokens, escalating GPU resource requirements during fine-tuning. To bridge this gap, we propose LR-SQL, a general dual-model SFT framework comprising a schema linking model and an SQL generation model. At the core of our framework lies the schema linking model, which is trained on a novel downstream task termed slice-based related table filtering. This task dynamically partitions a database into adjustable slices of tables and sequentially evaluates the relevance of each slice to the input query, thereby reducing token consumption per iteration. However, slicing fragments destroys database information, impairing the model’s ability to comprehend the complete database. Thus, we integrate Chain of Thought (CoT) in training, enabling the model to reconstruct the full database context from discrete slices, thereby enhancing inference fidelity. Ultimately, the SQL generation model uses the result from the schema linking model to generate the final SQL. Extensive experiments demonstrate that our proposed LR-SQL reduces total GPU memory usage by 40% compared to baseline SFT methods, with only a 2% drop in table prediction accuracy for the schema linking task and a negligible 0.6% decrease in overall Text2SQL Execution Accuracy.
