Sidh – a Game Based Firefighter Training Simulation
Proceedings / International Conference on Information Visualisation, 2007This paper presents Sidh-a game based firefighter training simulator developed in cooperation between the University ofSkvde and the Swedish Rescue Services Agency. Sidh is based on computer game hardware and software solutions but adds a novel interaction model and gameplay specifically developed for the purpose of training firefighters. The simulator

SIDH-sign: an efficient SIDH PoK-based signature. [PDF]
IACR Cryptol. ePrint Arch., 2022 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.

A Simple and Compact Algorithm for SIDH with Arbitrary Degree Isogenies [PDF]
, 2017 We derive a new formula for computing arbitrary odd-degree isogenies between elliptic curves in Montgomery form. The formula lends itself to a simple and compact algorithm that can efficiently compute any low odd-degree isogenies inside the supersingular isogeny Diffie-Hellman (SIDH) key exchange protocol.

Parallel strategies for SIDH: Towards computing SIDH twice as fast
IEEE Transactions on Computers, 2021We present novel strategies and concrete algorithms for the parallel computation of the Supersingular Isogeny-based Diffie-Hellman key exchange (SIDH) protocol when executed on multi-core platforms. The most relevant design idea exploited by our approach is that of concurrently computing scalar multiplication operations along with a parallelized ...

SHealS and HealS: Isogeny-Based PKEs from a Key Validation Method for SIDH [PDF]
Lecture Notes in Computer Science, 2021 In 2016, Galbraith et al. presented an adaptive attack on the SIDH key exchange protocol. In SIKE, one applies a variant of the Fujisaki-Okamoto transform to force Bob to reveal his encryption key to Alice, which Alice then uses to re-encrypt Bob’s ...

eSIDH: the revenge of the SIDH. [PDF]
IACR Cryptol. ePrint Arch., 2020 The Supersingular Isogeny-based Diffie-Hellman key exchange protocol (SIDH) was introduced by Jao an De Feo in 2011. SIDH operates on supersingular elliptic curves defined over quadratic extension fields of the form GF($p^2$), where $p$ is a large prime ...

IACR Cryptol. ePrint Arch., 2019 We give a number of approaches which, to a newcomer, may seem like natural ways to attack the SIDH/SIKE protocol, and explain why each of these approaches seems to fail, at least with the specific setup and parameters of SIKE.

An attack on SIDH with arbitrary starting curve. [PDF]
IACR Cryptol. ePrint Arch., 2022 We present an attack on SIDH which does not require any endomorphism information on the starting curve. Our attack has subexponential complexity thus significantly reducing the security of SIDH and SIKE; our analysis and preliminary implementation ...
