My Google Scholar Profile

Ongoing Course (IIT Bombay): CS620: New Trends in Information Technology -- Blockchains


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. 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.
