Host-Based Intrusion Detection for VANETs: A Statistical Approach to Rogue Node Detection
TL;DR: The proposed application-layer IDS based on a cooperative information exchange mechanism is better for dynamic and fast-moving networks such as VANETs, as compared with other techniques available.
Journal ArticleDOI
PIndroid: A novel Android malware detection system using ensemble learning methods
Fauzia Idrees,Muttukrishnan Rajarajan,Mauro Conti,Thomas M. Chen,Yogachandran Rahulamathavan +4 more
TL;DR: PIndroid is the first solution that uses a combination of permissions and intents supplemented with Ensemble methods for accurate malware detection, and suggests that the proposed framework is effective in detection of malware apps.
Journal ArticleDOI
Privacy-Preserving Multi-Class Support Vector Machine for Outsourcing the Data Classification in Cloud
Yogachandran Rahulamathavan,Raphael C.-W. Phan,Suresh Veluru,Kanapathippillai Cumanan,Muttukrishnan Rajarajan +4 more
TL;DR: This paper proposes the first known client-server data classification protocol using support vector machine that performs PP classification for both two-class and multi-class problems and exploits properties of Pailler homomorphic encryption and secure two-party computation.
Journal ArticleDOI
User Collusion Avoidance Scheme for Privacy-Preserving Decentralized Key-Policy Attribute-Based Encryption
Yogachandran Rahulamathavan,Suresh Veluru,Jinguang Han,Fei Li,Muttukrishnan Rajarajan,Rongxing Lu +5 more
TL;DR: A privacy-preserving decentralized key-policy ABE scheme where each authority can issue secret keys to a user independently without knowing anything about his GID, which is the first decentralized ABE scheme with privacy- Preserving based on standard complexity assumptions.
