Supersingular isogeny Diffie–Hellman key exchange (SIDH or SIKE) is an insecure proposal for a post-quantum cryptographic algorithm to establish a secret key between two parties over an untrusted communications channel. It is analogous to the Diffie–Hellman key exchange, but is based on walks in a … See more For certain classes of problems, algorithms running on quantum computers are naturally capable of achieving lower time complexity than on classical computers. That is, quantum algorithms can solve certain … See more During a key exchange, entities A and B will each transmit information of 2 coefficients modulo p ) defining an elliptic curve and 2 elliptic … See more While several steps of SIDH involve complex isogeny calculations, the overall flow of SIDH for parties A and B is straightforward for … See more A predecessor to the SIDH was published in 2006 by Rostovtsev and Stolbunov. They created the first Diffie-Hellman replacement based on elliptic curve isogenies. Unlike the method of De Feo, Jao, and Plut, the method of Rostovtsev and Stolbunov used … See more The j-invariant of an elliptic curve given by the Weierstrass equation $${\displaystyle y^{2}=x^{3}+ax+b}$$ is given by the formula: See more The most straightforward way to attack SIDH is to solve the problem of finding an isogeny between two supersingular elliptic curves with the same number of points. At the time of the original publication due to De Feo, Jao and Plût, the best attack known against SIDH … See more The following parameters were taken as an example by De Feo et al.: p = prime for the key exchange with wA = 2, wB = 3, eA = 63, eB = 41, and f = 11. Thus p = (2 ·3 ·11) - 1.
