Formal Verification of a Constant-Time Preserving C Compiler
Compilation Formal verification Constant-time security
2019/8/19
Timing side-channels are arguably one of the main sources of vulnerabilities in cryptographic implementations. One effective mitigation against timing side-channels is to write programs that do not pe...
One Bit is All It Takes: A Devastating Timing Attack on BLISS’s Non-Constant Time Sign Flips
Lattice-Based Cryptography Cryptanalysis BLISS
2019/8/7
As one of the most efficient lattice-based signature schemes, and one of the only ones to have seen deployment beyond an academic setting (e.g., as part of the VPN software suite strongSwan), BLISS ha...
A new implementation of Falcon is presented. It solves longstanding issues in the existing reference code: the new implementation is constant-time, it does not require floating-point hardware (though ...

Side-channel Attack Post-quantum Cryptography Code-based Cryptography
2019/7/15
In the last few years, post-quantum cryptography has received much attention. NIST is running a competition to select some post-quantum schemes as standard. As a consequence, implementations of post-q...
GALACTICS: Gaussian Sampling for Lattice-Based Constant-Time Implementation of Cryptographic Signatures, Revisited
Timing Attack Phase Retrieval algorithms Constant-time Implementation
2019/5/21
In this paper, we propose a constant-time implementation of the BLISS lattice-based signature scheme. BLISS is possibly the most efficient lattice-based signature scheme proposed so far, with a level ...
Fast and simple constant-time hashing to the BLS12-381 elliptic curve
hash functions elliptic curve cryptosystem implementation
2019/4/23
Pairing-friendly elliptic curves in the Barreto-Lynn-Scott family have experienced a resurgence in popularity due to their use in a number of real-world projects. One particular Barreto-Lynn-Scott cur...
A Faster Constant-time Algorithm of CSIDH keeping Two Torsion Points
CSIDH post-quantum cryptography Isogeny-based cryptography
2019/4/3
At ASIACRYPT 2018, Castryck, Lange, Martindale, Panny and Renes proposed CSIDH, which is a key-exchange protocol based on isogenies between elliptic curves, and a candidate for post-quantum cryptograp...

2019/3/21
We present an optimized, constant-time software library for commutative supersingular isogeny Diffie-Hellman key exchange (CSIDH) proposed by Castryck et al. which targets 64-bit ARM processors. The p...

Lattice-based cryptography Decryption failures Error-correcting codes
2019/2/25
Decryption failure is a common phenomenon in most lattice-based public-key schemes. To reduce the rate of decryption failure, application of error correction code can be helpful. However, the literatu...

Lattice-based crypto Discrete Gaussian sampling Constant-time
2019/1/2
The discrete Gaussian sampler is one of the fundamental tools in implementing lattice-based cryptosystems. However, a naive discrete Gaussian sampling implementation suffers from side-channel vulnerab...

CSIDH Post-Quantum Cryptography constant-time
2018/12/19
The recently proposed CSIDH primitive is a promising candidate for post quantum static-static key exchanges with very small keys. However, until now there is only a variable-time proof-of-concept impl...

Lucky 13 attack TLS Side-channel cache attacks
2018/8/20
Today, about 10% of TLS connections are still using CBC-mode cipher suites, despite a long history of attacks and the availability of better options (e.g. AES-GCM). In this work, we present three new ...
Rounded Gaussians -- Fast and Secure Constant-Time Sampling for Lattice-Based Crypto
Post-quantum cryptography lattice-based cryptography sig- natures
2017/10/25
This paper suggests to use rounded Gaussians in place of dis- crete Gaussians in rejection-sampling-based lattice signature schemes like BLISS. We show that this distribution can efficiently be sample...
