Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chamel...
Abstract. Chameleon signatures are based on well established hashand-sign paradigm, where a chameleon hash function is used to compute the cryptographic message digest. Chameleon s...
In 1999, two signature schemes based on the flexible RSA problem (a.k.a. strong RSA problem) were independently introduced: the Gennaro-Halevi-Rabin (GHR) signature scheme and the...
Abstract. Chameleon signatures simultaneously provide the properties of nonrepudiation and non-transferability for the signed message. However, the initial constructions of chamele...
Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...
