Memory/memory annex verification/authentication transmitted digital words having transmission using verification group structure with available signatures combined/group signatures and verified/identical signatures same group authorized

摘要

The digital word verification method has digital word elements transmitted from a source (4) to a destination (2) using a verification group signature. At the source level the available signatures for each digital word are combined, and signatures obtained. The grouped signatures are sent to the destination, and submitted to a calculation algorithm and the verification value compared with the grouped signature. The presence of identical signatures in the same group is authorized.
