The algorithms use arithmetic operations on elliptic curves defined over finite fields and compute maps, so-called isogenies, between such curves. The security of SIDH and SIKE relies on the hardness of finding a specific isogeny between two such elliptic curves, or equivalently, of finding a path between them in the isogeny graph. This problem is different from that of computing discrete logarithms on a single elliptic curve.<\/p>\n<p>The SIDH protocol was first introduced by Jao and De Feo in 2011 and is at the core of a public key encryption scheme which is then used to construct the key encapsulation mechanism SIKE. Further details about the design and performance of SIKE can be accessed in the links below.<\/p>\n<h2>Learn more:<\/h2>\n<p><a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"http:\/\/sike.org\/\" target=\"_blank\" rel=\"noopener\">SIKE homepage<\/a><br \/>\n<a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"https:\/\/github.com\/Microsoft\/PQCrypto-SIKE\" target=\"_blank\" rel=\"noopener\">SIKE GitHub<\/a><\/p>\n<p>More information on this work can also be found on our main\u00a0<a href=\"https:\/\/www.microsoft.com\/en-us\/research\/project\/post-quantum-cryptography\/\">Post-Quantum Cryptography<\/a> Project page.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SIKE and SIDH are insecure and should not be used.
