Leuvenshtein: Efficient FHE-based Edit Distance Computation with Single Bootstrap per Cell
Wouter Legiest, Jan-Pieter D'Anvers, Bojan Spasic +2
This paper presents a novel approach to calculating the Levenshtein (edit) distance within the framework of Fully Homomorphic Encryption (FHE), specifically targeting third-generat…
Rudraksh: A compact and lightweight post-quantum key-encapsulation mechanism
Suparna Kundu, Archisman Ghosh, Angshuman Karmakar +2
Resource-constrained devices such as wireless sensors and Internet of Things (IoT) devices have become ubiquitous in our digital ecosystem. These devices generate and handle a majo…
Masking Gaussian Elimination at Arbitrary Order, with Application to Multivariate- and Code-Based PQC
Quinten Norga, Suparna Kundu, Uttam Kumar Ojha +3
Digital signature schemes based on multivariate- and code-based hard problems are promising alternatives for lattice-based signature schemes, due to their small signature size. Gau…
Scabbard: An Exploratory Study on Hardware Aware Design Choices of Learning with Rounding-based Key Encapsulation Mechanisms
Suparna Kundu, Quinten Norga, Angshuman Karmakar +3
Recently, the construction of cryptographic schemes based on hard lattice problems has gained immense popularity. Apart from being quantum resistant, lattice-based cryptography all…
Carry Your Fault: A Fault Propagation Attack on Side-Channel Protected LWE-based KEM
Suparna Kundu, Siddhartha Chowdhury, Sayandeep Saha +3
Post-quantum cryptographic (PQC) algorithms, especially those based on the learning with errors (LWE) problem, have been subjected to several physical attacks in the recent past. A…
On the Masking-Friendly Designs for Post-Quantum Cryptography
Suparna Kundu, Angshuman Karmakar, Ingrid Verbauwhede
Masking is a well-known and provably secure countermeasure against side-channel attacks. However, due to additional redundant computations, integrating masking schemes is expensive…
A practical key-recovery attack on LWE-based key-encapsulation mechanism schemes using Rowhammer
Puja Mondal, Suparna Kundu, Sarani Bhattacharya +2
Physical attacks are serious threats to cryptosystems deployed in the real world. In this work, we propose a microarchitectural end-to-end attack methodology on generic lattice-bas…
