Mediated Signature Scheme provides an efficient method for fast revocation of a user's identity in identity. (ID)-based cryptosystems. The only ID-based ...
The proposed scheme is ID-based, but without any assumption of pre-fixed trusted relationship between users and PKG, which effectively solves the problem ...
