Research Overview

As one of the earliest institutions in China to carry out information security and confidentiality talent training, the School of Cyber Security (National Security College) of Beijing Jiaotong University has established a comprehensive and in-depth research system oriented to national strategic needs and cutting-edge technology development. Rooted in the international cyber security and industrial digital transformation, our research focuses on breaking through core technical bottlenecks and providing high-level intellectual support for the protection of cyber security and key industries.

Research Foundation & Academic Status

Our research journey began with the establishment of the Information Security Architecture Research Center in 2001. We were among the first batch of institutions nationwide to obtain the doctoral degree authorization for the first-level discipline of cyber space security in 2016, and were approved as a Beijing High-precision Discipline in 2019, undertaking the construction of the "New Generation Information Technology - Data Security and Privacy Protection" direction. With a complete research ecosystem covering theory, technology and application platforms, we have formed a mature scientific research support system and talent training core, and have become a high-level cyber security research and talent training base.

Core Research Directions

Combining disciplinary advantages and industrial demands, we have built three characteristic and leading research directions:

1. Intelligent Transportation & IoT Security
   Focusing on the security challenges of rail transit, connected vehicles and smart city scenarios, we specialize in research on vehicle-road coordination security protocols, railway big data privacy protection, and industrial IoT terminal security. Our achievements have been applied to major projects such as the Beijing Shanghai high-speed railway and Xiong'an New Area intelligent transportation system, providing core security guarantees for the digital transformation of transportation industries.

2. Blockchain & Web3.0 Security
   We conduct in-depth research on decentralized identity authentication, smart contract vulnerability detection, and anti-malicious takeover of blockchain systems. Our team won the Distinguished Paper Award at the top international conference ACM CCS for its research on DPOS blockchain governance security, marking the first such award for Chinese scholars in the blockchain field of cybersecurity. We have also developed a general framework for provable repair of neural network defects that outperforms existing methods in key task indicators. In cryptography, we focus on advanced technologies including homomorphic encryption, multi-party secure computation, and post-quantum cryptography, supporting the construction of security systems for blockchain-based Web 3.0 applications.

3. Cryptography Technologies & AI Applications
   Addressing technical frontiers in AI security, we explore adversarial machine learning, deepfake detection, and provable repair of neural network defects. We have developed a general framework for provable repair of neural network defects that outperforms existing methods in key task indicators. In cryptography, we research advanced cryptography algorithms and privacy computing technologies, supporting the construction of the education industry application infrastructure.

Research Platforms & Conditions

We have built a multi-level platform system integrating national, provincial and ministerial levels to support innovative research:

• National-level platforms: Central and State Organs Confidentiality Education and Training Platform, Education Industry Application Cryptography Research Center

• Provincial-level platforms: Beijing Key Laboratory of Intelligent Transportation Data Security and Privacy Protection

These platforms provide advanced experimental environments for vulnerability mining, security analysis, and large-scale system security verification, and undertake important tasks such as national confidentiality technology training and cyber security exercise organization.

Research Achievements

• Project undertakings: We have undertaken major projects including national key R&D programs, key projects of the National Natural Science Foundation of China, and major projects of China State Railway Group, forming a systematic research layout.

• Academic influence: Our research results are formally published in top international conferences such as ACM CCS and IEEE S&P, and we have won more than 10 provincial and ministerial science and technology awards including the Ministry of Education Science and Technology Progress Award.

International Cooperation & Academic Exchange

We have established long-term cooperative relationships with world-renowned universities including Purdue University (USA), Imperial College London (UK), and Nanyang Technological University (Singapore). Through joint research, student exchange programs, and international conference participation, we actively participate in global cyber security governance discussions and promote the internationalization of our research achievements.

Guided by the national "Cyber Power" strategy, we will continue to deepen interdisciplinary research, strengthen industry-university research integration, and strive to build a world-class cyber security research center that serves national needs and leads technological innovation.
