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

retrieve previously saved precomputation.

Reimplemented from PK_Precomputation.

Definition at line 50 of file mqv.cpp.

void MQV::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.
