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). Websignature schemes are presented in which a threshold number of Pointcheval-Sanders signa-tures [PS16] are aggregated to form a polynomial-based [McD20] aggregate/master signature (and vice-versa). arianVt switched threshold signatures leveraging Camenisch-Lysyanskaya signatures [CL04] also appear possible. The layout of this paper is as follows.

Indeed, with those signature schemes, all signers would have to agree on a common randomness. the sokapet https://gmaaa.net

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.

WebThe security of our scheme is based on a new complexity assumption that is obtained by generalizing the Pointcheval–Sanders (PS) assumption. Although our generalized PS (GPS) assumption is interactive, we prove that, under the (2,1)-discrete logarithm assumption, the new GPS assumption holds in the algebraic group model. References 1.
