SIKE is an isogeny-based key encapsulation suite based on pseudo-random walks in supersingular isogeny graphs, that was submitted to the NIST standardization process on post …

It is analogous to the Diffie–Hellman key exchange, but is based on walks in a supersingular isogeny graph and was designed to resist cryptanalytic attack by an adversary in possession …

SIKE is a family of post-quantum key encapsulation mechanisms based on the Supersingular Isogeny Diffie-Hellman (SIDH) key exchange protocol. The algorithms use arithmetic …

Sep 15, 2022 · Use of the supersingular isogeny key encapsulation (SIKE) protocol described in this document involves arithmetic operations of elliptic curves over finite fields. This section …

Indeed, it is occasionally an experience of the author that the sheer amount of background and jargon needed to get an isogeny-based talk o the ground is enough to overwhelm audience …

Supersingular Isogeny Key Encapsulation (SIKE) [4] is a post-quantum cryptography key encapsulation method for key exchange, and is based on Supersingular Isogeny Diffie …

Feb 5, 2025 · SIKE, an isogeny-based KEM, provides a high level of security against quantum adversaries by leveraging the computational difficulty of finding isogenies between …

SIKE advantages: Smallest public key size. Key compression has become almost free. Straightforward parameter selection. No decryption error, Gaussians, rejection sampling, etc. …

In principle, a non-generic attack against SIKE could conceivably exist; however, none is currently known. For generic attacks:
