Supersingular isogeny graphs in cryptography [PDF]
, 2019 We describe recent applications of expander graphs in cryptography, particularly supersingular isogeny graphs. The security of these cryptographic constructions relies on the assumption that computing paths in these graphs is practically infeasible, even

Isogeny-based cryptography in Julia/Nemo
ACM Communications in Computer Algebra, 2019The Couveignes-Rostovtsev-Stolbunov key-exchange protocol based on isogenies of elliptic curves is of interest because it may resist quantum attacks, but its efficient implementation remains a challenge. We briefly present the computations involved, and efficient algorithms to achieve the critical steps, with timing results for our implementations in ...

Fast Modular Multipliers for Supersingular Isogeny-Based Post-Quantum Cryptography
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2021As one of the postquantum protocol candidates, the supersingular isogeny key encapsulation (SIKE) protocol delivers promising public and secret key sizes over other candidates. Nevertheless, the considerable computations form the bottleneck and limit its practical applications.

Optimized Arithmetic Operations for Isogeny-Based Cryptography on Huff Curves
2020Up to now, the state-of-the-art implementations of Supersingular Isogeny Diffie-Hellman (SIDH) work with Montgomery curves or Edwards curves, due to the facts that such curve models provide high efficiency for elliptic curve arithmetic operations. In this work, we propose a new w-coordinate method to optimize the arithmetic operations on Huff curves ...

On Fast Calculation of Addition Chains for Isogeny-Based Cryptography
2017Addition chain calculations play a critical role in determining the efficiency of cryptosystems based on isogenies on elliptic curves. However, finding a minimal length addition chain is not easy; a generalized version of the problem, in which one must find a chain that simultaneously forms each of a sequence of values, is NP-complete.

The module action for isogeny based cryptography. [PDF]
IACR Cryptol. ePrint Arch.We extend the usual ideal action on oriented elliptic curves to a (Hermitian) module action on oriented (polarised) abelian varieties. Oriented abelian varieties are naturally enriched in $R$-modules, and our module action comes from the canonical power ...

Ultra-Fast Modular Multiplication Implementation for Isogeny-Based Post-Quantum Cryptography
2019 IEEE International Workshop on Signal Processing Systems (SiPS), 2019Supersingular isogeny key encapsulation (SIKE) protocol delivers promising public and secret key sizes over other post-quantum candidates. However, the huge computations form the bottleneck and limit its practical applications. The modular multiplication operation, which is one of the most computationally demanding operations in the fundamental ...
