Adaptive Quantum-Safe Cryptography for 6G Vehicular Networks via Context-Aware Optimization
Poushali Sengupta, Mayank Raikwar, Sabita Maharjan +2
Powerful quantum computers in the future may be able to break the security used for communication between vehicles and other devices (Vehicle-to-Everything, or V2X). New security m…
zkToken: Empowering Holders to Limit Revocation Checks for Verifiable Credentials
Praveensankar Manimaran, Mayank Raikwar, Thiago Garrett +3
Systems managing Verifiable Credentials are becoming increasingly popular. Unfortunately, their support for revoking previously issued credentials allows verifiers to effectively m…
A Review on Privacy in DAG-Based DLTs
Mayank Raikwar
Directed Acyclic Graph (DAG)-based Distributed Ledger Technologies (DLTs) have emerged as a promising solution to the scalability issues inherent in traditional blockchains. Howeve…
An LLM Framework For Cryptography Over Chat Channels
Danilo Gligoroski, Mayank Raikwar, Sonu Kumar Jha
