liboqs master branch algorithm datasheet: kem_sidh
Summary
- Name: SIDH
- Algorithm type: key exchange
- Note: SIDH is as ephemeral key exchange algorithm related to the SIKE KEM (sike.org) submitted to NIST. It is NOT secure to use it with static keys.
- Main cryptographic assumption: (supersingular) isogeny walk problem
- Submitters' website: https://github.com/Microsoft/PQCrypto-SIDH
- Added to liboqs by: Christian Paquin
