MQV domain for performing authenticated key agreement.
GROUP_PARAMETERS | doamin parameters |
COFACTOR_OPTION | cofactor option |
GROUP_PARAMETERS paramters include the curve coefcients and the base point. Binary curves use a polynomial to represent its characteristic, while prime curves use a prime number.

Provides the name of this algorithm.
The standard algorithm name can be a name like AES or AES/GCM. Some algorithms do not have standard names yet. For example, there is no standard algorithm name for Shoup's ECIES.
