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 ... 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.

WebSep 7, 2024 · A second issue is that their underlying base signature schemes, namely Camenisch–Lysyanskaya and Pointcheval-Sanders [41, 42] signatures, are not a priori suitable to a multi-signer setting as needed to distribute issuance. Indeed, with those signature schemes, all signers would have to agree on a common randomness.
