Research Interest

Blockchain-based Trust Computing: 

• Consensus Algorithm (합의 알고리즘, Byzantine fault tolerance, multi-block consensus) 

• Blockchain Security (피싱 탐지, ID 추론 공격 대응, 신뢰성 검증) 

Privacy-preserving System:

• Healthcare Data Exchange (환자 정보 공유, 의료 데이터 보안, 데이터 활용성)

• Re-identification Attack Defense (익명성 보호, 데이터 재식별 공격 방어, 프라이버시 강화)

• Split/Federated Learning (분산 학습, 프라이버시 보존형 AI, 협력적 모델 학습)

Intelligent Security & AI:

• Graph Neural Network (그래프 학습, GCN, embedding 기반 분석)

• Anomaly & Phishing Detection (블록체인 피싱 탐지, 보안 위협 예측, 이상 징후 검출)

• Generative AI & LLM Security ( AI 기반 보안 응용, 지능형 보안 시스템)
