An Identity-based Mediated Signature Scheme from Bilinear Pairing
It has always been a critical issue to find efficient methods for fast revocation of a user's identity in identity (ID)based cryptosystems. Unfortunately, none of the previous ID-based cryptography can find a practical way. Libert et al. and Baek et al. respectively propose an ID-based mediated encryption scheme based on the practical ID-based encryption scheme from bilinear pairing due to Boneh and Franklin. Both schemes provide an efficient method for immediate revocation of a user's identity. However, no ID-based mediated signature scheme from bilinear pairing has been found so far. The essential reason is that most of the previous ID-based signatures from bilinear pairing are no "good" enough to generate their mediated versions. In this paper, we first presents an ID-based signature scheme from bilinear pairing. It is secure against existential forgery under adaptively chosen message and ID attack in the random oracle model. Furthermore, it has the good propert...
