Looks pretty interesting: <i>&quot;These results show that, in practice, FourQ is around four to five times faster than the original NIST P-256 curve and between two and three times faster than curves that are currently under consideration as NIST alternatives, such as Curve25519.&quot;</i><p>Also check out FourQlib[1], MSR&#x27;s (MIT-licensed) C implementation of this research.<p>[1] <a href="http:&#x2F;&#x2F;research.microsoft.com&#x2F;en-us&#x2F;projects&#x2F;fourqlib&#x2F;" rel="nofollow">http:&#x2F;&#x2F;research.microsoft.com&#x2F;en-us&#x2F;projects&#x2F;fourqlib&#x2F;</a>
