NUMS

Microsoft Nothing Up My Sleeve Elliptic curves

NUMS (Nothing Up My Sleeve) curves, which are supported in the MSRElliptic Curve Cryptography Library (a.k.a. MSR ECCLib).

These curves are elliptic curves over a prime field, just like the NIST or Brainpool curves. However, the domain-parameters are choosen using a VERY TIGHT DESIGN SPACE to ensure, that the introduction of a backdoor is infeasable. For a desired size of s bits the prime p is choosen as p = 2^s - c with the smallest c where c>0 and p mod 4 = 3 and p being prime.
