First we revisit three - BGLS, MBGLS and GZZ verifiably encrypted signature schemes [2, 3, 6]. We find that they are all not strong unforgeable.We remark that the notion of existen...

Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a...
