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…
A 334W 0.158mm ASIC for Post-Quantum Key-Encapsulation Mechanism Saber with Low-latency Striding Toom-Cook Multiplication Authors Version
Archisman Ghosh, Jose Maria Bermudo Mera, Angshuman Karmakar +4
The hard mathematical problems that assure the security of our current public-key cryptography (RSA, ECC) are broken if and when a quantum computer appears rendering them ineffecti…
