I am an Associate Professor in
the Department of Computer Science and
at the Indian Institute
of Technology Bombay.
Research Interests: Computer and Network Security (blockchain, IoT security, Ransomware), Wireless Networks, Indoor positioning and navigation
Ongoing Course (IIT Bombay): CS762: Advanced Blockchain Technology
1. NDSS Paper on Blockchain: We have come up with a novel method to implement computationally intensive smart contracts on blockchains such as those of Ethereum, Bitcoin, Hyperledger etc. NDSS is a top-tier Computer Security Conference.
Paper Details: Sourav Das, Vinay Joseph Ribeiro, Abhijeet Anand, YODA: Enabling computationally intensive contracts on blockchains with Byzantine and Selfish nodes [arXiv link]
2. ACM Transactions paper on IoT Security: My student, Samuel Wedaj, has invented a decentralized attestation scheme for device swarms.
Paper Details: Samuel Wedaj, Kolin Paul, Vinay J. Ribeiro, DADS: Decentralised attestation of Device Swarms , ACM Transactions on Privacy and Security 2019.
3. RANSOMWARE Solution: My student, Saiyed Kashif Shaukat, has developed a multi-layered solution, implemented for Microsoft Windows, for a dreaded type of malware called Ransomware. Ransomware encrypts a user's files and asks for a ransom in order to decrypt files. The solution, called RansomWall, uses machine learning in one of its layers. The paper was presented at COMSNETS 2018 in January 2018.
