WebApr 10, 2015 · We proposed an efficient ring signature scheme in the bilinear groups for perfect anonymity, which is provably secure in the random oracle model under the co-CDH assumption. Our scheme is the first ring signature scheme whose computational complexity for pairing computations is independent of the ring size, i.e., it requires only two pairing ...

You need non-degeneracy in both arguments. For example, let ϕ ∈ V ∗ be non-zero and define B: K × V → K, B ( λ, v) = ϕ ( λ v). Then B ( λ, v) = 0 for all v ∈ V implies λ = 0, but B is not a perfect pairing if dim ( V) ≥ 2. Now assume that B is non-degenarate in both arguments.

However, no PVSS scheme using bilinear pairings is proposed. This paper presents the first pairing-based PVSS scheme. In the random oracle model and under the bilinear Diffie-Hellman assumption, the authors prove that the proposed scheme is a secure PVSS scheme.
