void DH::LoadPrecomputation ( BufferedTransformation & bt ) [virtual]

retrieve previously saved precomputation. Reimplemented from PK_Precomputation. Definition at line 46 of file dh.cpp.

void DH::Precompute ( unsigned int precomputationStorage = 16 ) [virtual]

The exact semantics of Precompute() is varies, but typically it means calculate a table of n objects that can be used later to speed up computation. Reimplemented from PK_Precomputation. Definition at line 41 of file dh.cpp.

save precomputation for later use. Reimplemented from PK_Precomputation. Definition at line 51 of file dh.cpp.

bool DH::ValidateDomainParameters ( RandomNumberGenerator & rng ) const

Definition at line 56 of file dh.cpp.
