We propose an undeniable signature scheme based on elliptic curve isogenies, and prove
its security under certain reasonable number-theoretic computational assumptions for which …

In this paper, we propose an Undeniable Blind Signature scheme (UBSS) based on
isogenies between supersingular elliptic curves. The proposed UBSS is an extension of the …

We present new candidates for quantum-resistant public-key cryptosystems based on the
conjectured difficulty of finding isogenies between supersingular elliptic curves. The main …

We present the first general-purpose digital signature scheme based on supersingular
elliptic curve isogenies secure against quantum adversaries in the quantum random oracle …

We present new candidates for quantum-resistant public-key cryptosystems based on the
conjectured difficulty of finding isogenies between supersingular elliptic curves. The main …

In this paper, we propose a practical signature scheme based on the alternating trilinear
form equivalence problem. Our scheme is inspired by the Goldreich-Micali-Wigderson's zero …

Signature schemes, proposed in 1976 by Diffie and Hellman, have become ubiquitous
across modern communications. They allow for the exchange of messages from one sender …

Strongly unforgeable signature schemes provide a more stringent security guarantee than
the standard existential unforgeability. It requires that not only forging a signature on a new …

We introduce a new signature scheme, SQISign,(for Short Quaternion and Isogeny
Signature) from isogeny graphs of supersingular elliptic curves. The signature scheme is …

We initiate the study of quantum-secure digital signatures and quantum chosen ciphertext
security. In the case of signatures, we enhance the standard chosen message query model …
