Efficiency of SIDH-based signatures (yes, SIDH)
In this note, we assess the efficiency of a supersingular isogeny Diffie-Hellman (SIDH)-based digital signature built on a weaker variant of a recent identification protocol proposed by Basso et al.

Compressed M-SIDH: an instance of compressed SIDH-like schemes with isogenies of highly composite degrees [PDF]
Recently, SIDH was broken by a series of attacks. To avoid the attacks, several new countermeasures, such as M-SIDH and binSIDH, have been developed. Different from SIDH, the new SIDH-like schemes have relatively large public key sizes.

Efficient Compression of SIDH Public Keys [PDF]
Supersingular isogeny Diffie-Hellman (SIDH) is an attractive candidate for post-quantum key exchange, in large part due to its relatively small public key sizes. A recent paper by Azarderakhsh, Jao, Kalach, Koziel and Leonardi showed that the public keys

An Efficient Key Recovery Attack on SIDH [PDF]
We present an efficient key recovery attack on the Supersingular Isogeny Diffie-Hellman protocol (SIDH). The attack is based on Kani\u27s reducibility criterion for isogenies from products of elliptic curves and strongly relies on the torsion point ...

A Polynomial Time Attack on Instances of M-SIDH and FESTA [PDF]
The recent devastating attacks on SIDH rely on the fact that the protocol reveals the images $\varphi(P)$ and $\varphi(Q)$ of the secret isogeny $\varphi : E_0 \rightarrow E$ on a basis $\{P, Q\}$ of the $N$-torsion subgroup $E_0[N]$ where $N^2 > \deg ...

A New Adaptive Attack on SIDH [PDF]
The SIDH key exchange is the main building block of SIKE, the only isogeny based scheme involved in the NIST standardization process. In 2016, Galbraith et al. presented an adaptive attack on SIDH.

Extended supersingular isogeny Diffie–Hellman key exchange protocol: Revenge of the SIDH
The supersingular isogeny Diffie–Hellman key exchange protocol (SIDH) was introduced by Jao and De Feo in 2011. SIDH operates on supersingular elliptic curves defined over Fp2, where p is a large prime number of the form p=4eA3eB−1 and eA and eB are ...

SIDH-sign: an efficient SIDH PoK-based signature [PDF]
We analyze and implement the SIDH PoK-based construction from De Feo, Dobson, Galbraith, and Zobernig. We improve the SIDH-PoK built-in functions to allow an efficient constant-time implementation.

Improved Torsion-Point Attacks on SIDH Variants [PDF]
SIDH is a post-quantum key exchange algorithm based on the presumed difficulty of finding isogenies between supersingular elliptic curves. However, SIDH and related cryptosystems also reveal additional information: the restriction of a secret isogeny to ...

Intradialytic Hypotensive Episodes are Only Occasionally Associated With Adverse Symptoms [PDF]
Introduction: Although intradialytic hypotension (IDH) is a frequent complication of hemodialysis (HD), a consensus definition is lacking. Adverse symptoms and/or interventions are a prerequisite in guidelines; however, a threshold-based blood pressure ...
