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
