On the Generic Construction of Identity-Based Signatures With Additional Properties
Source: University of Luxembourg
It has been demonstrated by Bellare, Neven, and Namprempre (Eurocrypt 2004) that identity-based signature schemes can be generically constructed from standard digital signature schemes. In this paper the authors consider the following natural extension: is there a generic construction of "Identity-based signature schemes with additional properties" (such as identity-based blind signatures, verifiably encrypted signatures, ...) from standard signature schemes with the same properties? The results show that this is possible for a number of properties including proxy signatures; (partially) blind signatures; verifiably encrypted signatures; undeniable signatures; forward-secure signatures; (strongly) key insulated signatures; online/offline signatures; threshold signatures; and (with some limitations) aggregate signatures.
