Forward Secure Proxy Signature Scheme over NTRU Lattice [PDF]

open access: yesJisuanji gongcheng, 2019
Most existing forward secure proxy signature schemes are constructed based on traditional number theory problems,such as large integer decomposition,discrete logarithm and bilinear pairs,and they are easy to be cracked in a quantum computing environment ...

New Lattice-Based Short Proxy Signature Scheme With Fewer System Parameters in the Standard Model

open access: yesIEEE 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.

A Short Linearly Homomorphic Proxy Signature Scheme

open access: yesIEEE Access, 2018
Linearly homomorphic signature schemes allow the performance of linear computations on authenticated data. They are important primitives for many applications, such as electronic voting, smart grids, electronic health records, and so on.

Proxy Signature with Revocation

open access: yes, 2016
Proxy signature is a useful cryptographic primitive that allows signing right delegation. In a proxy signature scheme, an original signer can delegate his/her signing right to a proxy signer or a group of proxy signers who can then sign documents on behalf of the original signer.

An Efficient Proxy Signature Scheme with Revocation [PDF]

open access: yesInformatica, 2004
Summary: A proxy signature allows a designated person, called a proxy signer, to sign the message on behalf of the original signer. Proxy signatures are very useful tools when one needs to delegate his/her signing capability to other party. A number of proxy signature schemes have been proposed and succeeded for proxy delegations, but the schemes are ...

Post quantum proxy signature scheme based on the multivariate public key cryptographic signature

open access: yesInternational 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.

Partially Blind Proxy Re-Signature Scheme Without Bilinear Pairing [PDF]

open access: yesJisuanji gongcheng, 2020
To address complex bilinear pairing operations and certificate management problems of existing blind proxy re-signature schemes,by using WANG’s scheme for reference,this paper proposes a partially blind proxy re-signature scheme without bilinear pairing ...

An Improved Proxy Multi-Signature, Multi-Proxy Signature and Multi-Proxy Multi-Signature Scheme

open access: yesJournal of Networks, 2011
Zhou’s proxy multi-signature scheme was a safe and effective scheme, but this scheme was not safety enough. In this work, security analysis was given to the scheme and results showed that the scheme was very easy aggressed by the forgery attack. The paper proposed that any attacker can sign some certain unauthorized messages after the attacker knows a ...

Provably secure and efficient proxy signature scheme

open access: yesTongxin xuebao, 2014
The size of proxy signature secret key in proxy signature scheme based on lattice basis delegation in fixed di-mension or bonsai tree is greater than that of original signature secret key.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
