Anonymous Proxy Signatures [PDF]
, 2008 We define a general model for consecutive delegations of signing rights with the following properties: The delegatee actually signing and all intermediate delegators remain anonymous. As for group signatures, in case of misuse, a special authority can open signatures to reveal the chain of delegations and the signer's identity.

Group–Proxy Signature Scheme: A Novel Solution to Electronic Cash
Journal of Intelligent Systems, 2013 Proxy signature and group signature are two basic cryptographic primitives. Due to their valuable characteristics, many schemes have been put forward independently and they have been applied in many practical scenarios up to the present.

New Lattice-Based Short Proxy Signature Scheme With Fewer System Parameters in the Standard Model
IEEE Access, 2022 Proxy signature schemes safely ensure that an original signer transfers the signing right to a proxy signer, and a variety of these schemes have been developed for secure applications.

Post quantum proxy signature scheme based on the multivariate public key cryptographic signature
International Journal of Distributed Sensor Networks, 2020 Proxy signature is a very useful technique which allows the original signer to delegate the signing capability to a proxy signer to perform the signing operation.

Post-Quantum Secure Identity-Based Proxy Blind Signature Scheme on a Lattice
Entropy, 2023 Blind signatures have been widely applied when privacy preserving is required, and the delegation of blind signature rights and a proxy blind signature (Proxy-BS) become necessary when the signer cannot sign.

Empirical analysis of the solar contribution to global mean air surface temperature change [PDF]
, 2009 The solar contribution to global mean air surface temperature change is analyzed by using an empirical bi-scale climate model characterized by both fast and slow characteristic time responses to solar forcing: $\tau_1 =0.4 \pm 0.1$ yr, and $\tau_2= 8 \pm

Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation
Entropy, 2022 We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel.
