Detailed Description

template<class SCHEME_OPTIONS>
class DL_VerifierImpl< SCHEME_OPTIONS >

Discrete Log (DL) verifier implementation.

Template Parameters
SCHEME_OPTIONSoptions for the scheme

Member Function Documentation

template<class SCHEME_OPTIONS >
PK_MessageAccumulator* DL_VerifierImpl< SCHEME_OPTIONS >::NewVerificationAccumulator ( ) const
inlinevirtual

Create a new HashTransformation to accumulate the message to be verified.

Returns
a pointer to a PK_MessageAccumulator

NewVerificationAccumulator() can be used with all verification methods. Verify() will autimatically delete the accumulator pointer. The caller is responsible for deletion if a method is called that takes a reference.

Implements PK_Verifier.
