Makalah ini mempertimbangkan masalah mengimbangi kebolehkesanan dan tidak dikenali dalam tandatangan pengesah yang ditetapkan (DVS), yang merupakan sejenis tandatangan berorientasikan kumpulan. Iaitu, kami mencadangkan tandatangan pengesah ditetapkan boleh dituntut (CDVS), di mana penandatangan boleh mendakwa bahawa dia memang mencipta tandatangan kemudian. DVS Ordinal tidak menyediakan sebarang kebolehkesanan, yang mungkin menunjukkan ketaknamaan yang terlalu kuat. Oleh itu, menambahkan kebolehtuntutan, yang boleh dilihat sebagai sejenis kebolehkesanan, menyederhanakan kerahasiaan nama. Kami menunjukkan dua pembinaan generik CDVS daripada (i) tandatangan cincin, tandatangan (bukan cincin), fungsi pseudorandom dan skim komitmen, dan (ii) tandatangan cincin boleh dituntut (oleh Park dan Sealfon, CRYPTO'19).

Abstract: This paper considers the problem of balancing traceability and anonymity in designated verifier signatures (DVS), which are a kind of group-oriented signatures. That is, we propose claimable designated verifier signatures (CDVS), where a signer is able to claim that he/she indeed created a signature later. Ordinal DVS does not provide any traceability, which could indicate too strong anonymity. Thus, adding claimability, which can be seen as a sort of traceability, moderates anonymity. We demonstrate two generic constructions of CDVS from (i) ring signatures, (non-ring) signatures, pseudorandom function, and commitment scheme, and (ii) claimable ring signatures (by Park and Sealfon, CRYPTO'19).
