Mission Overview
Pioneering secure, high-performance computing frameworks for the future of digital transactions.
The Security, Privacy and Trust Lab (SPriT Lab) at the Indian Institute of Technology Jodhpur focuses on solving complex scientific problems that occur at the intersection of cryptography and decentralized engineering. Our mission is to build robust systems where cryptographic guarantees ensure absolute privacy and security, even in highly hostile off-chain networks.
Our current breakthroughs include developing scalable mechanisms for Payment Channel Networks (PCNs) to avoid channel exhaustion, designing wormhole-resistant routing paths, and integrating zero-knowledge proofs to enhance privacy in decentralized AI environments.
Key Research Directions
Our lab explores multiple thrust areas within security, cryptographic protocols, and distributed trust systems.
Zero-Knowledge Proofs
Leveraging zk-SNARKs and cryptographic commitments to enable secure transaction verification and private auditing on distributed ledgers.
Trustworthy AI/ML
Enabling privacy-preserving collaborative learning frameworks (Federated Learning) that protect input models and raw data.
Secured Healthcare System
Designing cryptographically sealed, access-controlled record systems that protect sensitive patient medical data during remote sharing and clinical diagnostics.
Security, Privacy and Trust
Formulating formal models to evaluate peer-to-peer trust dynamics and enforce mathematically provable security bounds on distributed protocols.
Social Internet of Vehicles
Establishing anonymous trust management and privacy-preserving routing systems for intelligent transit networks.
Unmanned Aerial Vehicle
Securing telemetry communications and swarm coordination in unmanned drone networks through lightweight, low-latency cryptographic protocols.
Wi-Fi Sensing
Enabling non-invasive activity recognition using ambient wireless signals while developing safeguards to protect spatial privacy and user anonymity.
Applied Cryptography
Constructing custom multi-signatures, threshold schemes, and time-lock commitments to secure multi-hop routing and scaling in decentralized networks.
