Quantum Fire with Delegated Cloning
Rohit Chatterjee, Ananta Mukherjee, Vir Pathak +1
Quantum fire is a recently introduced cryptographic primitive consisting of efficiently preparable quantum states, called \emph{flames}, that admit efficient cloning but resist eff…
A quantum algorithm for one-shot signatures
Gopikrishnan Muraleedharan, Minh Thuy Truc Pham, Vir Pathak +11
We provide a pre-obfuscation circuit-level implementation of an efficient one shot signature scheme, which has known applications to delegated signatures, secure token transfer, an…
One-Phase Batch Update on Sparse Merkle Trees for Rollups
Boqian Ma, Vir Nath Pathak, Lanping Liu +1
A sparse Merkle tree is a Merkle tree with fixed height and indexed leaves given by a map from indices to leaf values. It allows for both efficient membership and non-membership pr…
Lattices, Homomorphic Encryption, and CKKS
Vir Pathak
This is a survey on some topics in Lattice based cryptography and Homomorphic Encryption. In particular, we define some lattice problems, LWE and RLWE, and state the reductions giv…
