Avoiding Trusted Setup in Isogeny-based Commitments

Tako Boris Fouotsa

In 2021, Sterner proposed a commitment scheme based on supersingular isogenies. For this scheme to be binding, one relies on a trusted party to generate a starting supersingular elliptic curve of unknown endomorphism ring. In fact, the knowledge of the end ...

SILBE: An Updatable Public Key Encryption Scheme from Lollipop Attacks

Serge Vaudenay, Tako Boris Fouotsa

We present a new post-quantum Public Key Encryption scheme (PKE) named Supersingular Isogeny Lollipop Based Encryption or SILBE. SILBE is obtained by leveraging the generalized lollipop attack of Castryck and Vercauteren on the M-SIDH Key exchange by Fouot ...

Exploring SIDH-Based Signature Parameters

Tako Boris Fouotsa, Laurane Chloé Angélina Marco, Andrea Basso

Isogeny-based cryptography is an instance of post-quantum cryptography whose fundamental problem consists of finding an isogeny between two (isogenous) elliptic curves E and E′. This problem is closely related to that of computing the endomorphism ring of ...
