Since the initial standardization of Elliptic Curve Cryptography (ECC [RFC6090]) in [SEC1], there has been significant progress related to both efficiency and security of curves and implementations. Notable examples are algorithms protected against certain side-channel attacks, various "special" prime shapes that allow faster modular arithmetic, and a larger set of curve models from which to choose. There is also concern in the community regarding the generation and potential weaknesses of the curves defined by NIST [NIST].

                       Elliptic Curves for Security


   This memo specifies two elliptic curves over prime fields that offer    a high level of practical security in cryptographic applications,    including Transport Layer Security (TLS).  These curves are intended    to operate at the ~128-bit and ~224-bit security level, respectively,    and are generated deterministically based on a list of required    properties.
