Wouter Castryck and Thomas Decru presented an efficient key recovery attack on the SIDH protocol. As a result, the secret key of SIKEp751 can be recovered in a matter of hours. The SIKE and SIDH schemes will be removed from oqs 0.7.2.
The affected schemes are the oqs::kem::Algorithm::Sike*
and oqs::kem::Algorithm::Sidh*
enum variants.
