TAILIEUCHUNG - Classification of Signature-only Signature Models

We introduce a set of criterions for classifying signature-only signature models. By the criterions, we classify signature models into 5 basic types and 69 general classes. | Classification of Signature-only Signature Models Zhengjun Cao Department of Mathematics Shanghai University China 200444. zjcamss@ Abstract We introduce a set of criterions for classifying signature-only signature models. By the criterions we classify signature models into 5 basic types and 69 general classes. Theoretically 21140 kinds of signature models can be deduced by appropriately combining different general classes. The result comprises almost existing signature models. We also contribute a lot of new signature models. Moreover we find the three signature models . group-nominee signature multi-nominee signature and threshold-nominee signature are of great importance in light of our classification.

For example multi-signature 1 threshold signature 2 group signature 3 threshold group signature 4 ring signature 5 linkable ring signature 6 threshold ring signature 7 proxy signature 8 multi-proxy signature 9 threshold proxy signature 10 proxy ring signature 11 proxy multisignature 12 multi-proxy multi-signature 13 threshold proxy multi-signature 14 designated-verifier signature 15 multiple designated-verifier signature 16 nominative signature 17 undeniable signature 18 designated-confirmer signature 19 multiple designated-confirmer signature 19 blind signature 20 fair blind signature 21 restrictive blind signature 22 partially blind signature 23 restrictive partially blind signature 24 ID-based signature 25 forward-secure signature 26 designated-verifier proxy signature 27 nominative proxy signature 28 undeniable multi-signature 29 undeniable proxy multi-signature 30 blind multi-signature 31 threshold blind signature 32 threshold partially blind signature 33 group blind signature 34 threshold ring blind signature 35 proxy blind .
