New Forward Secure Signature Scheme Bilinear Maps
2009/4/10
Forward-secure signatures are used to defeat signature forgeries in cases of key
exposure. In this model, the signature key evolves with time and it is
computationally infeasible for an adversary to...
In this paper, we present two forward secure signature schemes based on gap Diffe-Hellman groups and prove these schemes to be secure in the sense of slightly stronger security
notion than that by Be...
