Power side-channel attacks exploit data-dependent variations in a CPU's power
consumption to leak secrets. In this paper, we show that on modern Intel (and AMD) x86 …

The SIDH protocol is an isogeny-based key exchange protocol using supersingular
isogenies, designed by Jao and De Feo in 2011. The protocol underlies the SIKE algorithm …

Generating a supersingular elliptic curve such that nobody knows its endomorphism ring is a
notoriously hard task, despite several isogeny-based protocols relying on such an object. A …

We present KEMTLS, an alternative to the TLS 1.3 handshake that uses key-encapsulation
mechanisms (KEMs) instead of signatures for server authentication. Among existing post …

Post-quantum cryptographic primitives have a range of trade-offs compared to traditional
public key algorithms, either having slower computation or larger public keys and …

Recent independent analyses by Bonnetain–Schrottenloher and Peikert in Eurocrypt 2020
significantly reduced the estimated quantum security of the isogeny-based commutative …

We investigate all NIST PQC Round 3 KEM candidates from the viewpoint of fault-injection
attacks: Classic McEliece, Kyber, NTRU, Saber, BIKE, FrodoKEM, HQC, NTRU Prime, and …

Abstract The Supersingular Isogeny Diffie-Hellman (SIDH) protocol has been the main and
most efficient isogeny-based encryption protocol, until a series of breakthroughs led to a …

Signature schemes based on the MPC-in-the-head approach (MPCitH) have either been
designed by taking a proof system and selecting a suitable symmetric-key primitive (Picnic …

Quantum computing is a game-changing technology that will push the boundaries of
cybersecurity and cryptography of power infrastructures including distributed energy …
