Generic security-amplifying methods of ordinary digital signatures
2012
Information Sciences
Preserved Fulltext
Digital signatures are one of the most fundamental primitives in cryptography. ...
In the first paradigm, based on a weakly-secure signature scheme, the construction of a fully-secure signature scheme requires one-time signature additionally. ...
