Security
|

* An adversary with access to precise enough timing information (typically, a
|
||||
co-located process) could recover a Curve25519 or Curve448 static ECDH key
|
||||
after inputting a chosen public key and observing the victim performing the
|
||||
corresponding private-key operation. Found and reported by Leila Batina,
|
||||
Lukas Chmielewski, Björn Haase, Niels Samwel and Peter Schwabe.
