WebThe PS (Pointcheval Sanders) Short Randomizable Signature was defined in [1], and uses crypto pairs to produce a signature which can be randomized. Initially we have two pairing points (\(g_1\) on the G1 curve, and \(g_2\) on the G2 curve). WebNov 6, 2024 · Short Randomizable signatures by David Pointcheval and Olivier Sanders. Implements 2 variations as described in the paper in sections 4.2 and 6.1 respectively. Scheme in 6.1 was presented to make blind signatures efficient however there are ways to do blind signatures with 4.2 but they are relatively inefficient.

WebWe then give an efficient construction relying on the pairing-based Pointcheval-Sanders (PS) signature scheme (CT-RSA 2024), which yields very short group signatures of two first-group elements and three field elements. We also give a simpler variant of our scheme in which issuance requires the participation of all n_I issuers, but still ...

Indeed, with those signature schemes, all signers would have to agree on a common randomness. bound series by christine feehan
