Ongoing Course (IIT Bombay): CS224: Computer Networks
1. Blockchain
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, NDSS 2019 [arXiv link] ICPE Paper on Blockchain: Our measurements of the Ethereum blocks and transactions show that miners can speed up block validation significantly using cached state. Paper Details: Nitin Awathare, Sourav Das, Vinay J. Ribeiro, Umesh Bellur, RENOIR: Accelerating Blockchain Validation using State Caching, ICPE 2021 |
2. IoT Security
Paper Details: Samuel Wedaj, Kolin Paul, Vinay J. Ribeiro, DADS: Decentralised attestation of Device Swarms , ACM Transactions on Privacy and Security 2019.

3. Machine learning for Malware detection 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. Paper Details: Saiyed Kashif Shaukat, Vinay J. Ribeiro, RansomWall: A Layered Defense System against Cryptographic Ransomware Attacks using Machine Learning, COMSNETS 2018.
