Identity-Based Aggregate Signatures [PDF]

open access: yes, 2006
An aggregate signature is a single short string that convinces any verifier that, for all 1 ≤ i ≤ n, signer Si signed message Mi, where the n signers and n messages may all be distinct. The main motivation of aggregate signatures is compactness. However, while the aggregate signature itself may be compact, aggregate signature verification might require

A Lattice-Based Unordered Aggregate Signature Scheme Based on the Intersection Method

open access: yesIEEE Access, 2018
An aggregate signature turns multi-message multi-authentication into multi-message single-authentication, reducing the required storage space, transmission cost, and number of verification calculations, and is suitable for fast message authentication in ...

Pointcheval-Sanders Signature-Based Synchronized Aggregate Signature

open access: yes, 2023
Synchronized aggregate signature is a special type of signature that all signers have a synchronized time period and allows aggregating signatures which are generated in the same period. This signature has a wide range of applications for systems that have a natural reporting period such as log and sensor data, or blockchain protocol.

Forward-Secure Multi-User Aggregate Signatures Based on zk-SNARKs

open access: yesIEEE Access, 2021
As a solution to mitigate the key exposure problems in the digital signature, the forward security has been proposed. The forward security guarantees the integrity of the messages generated in the past despite leaks of a current time period secret key by

Forward Secure Sequential Aggregate Signature Schemes on Lattice

open access: yesJisuanji kexue yu tansuo, 2021
The forward secure sequential aggregate (Fss-Agg) signature has the advantages of forward secure signature and the sequential aggregate signature at the same time. Since its proposal in 2007, it has been widely applied in many application scenarios, such

Certificateless-based efficient aggregate signature scheme with universal designated verifier

open access: yesTongxin xuebao, 2015
The security model of the certificateless aggregate signature scheme with universal designated verifier was studied,and then a certificateless aggregate signature scheme with universal designated verifier using bilinear pairings was proposed.In the ...

Insecurity of a Certificateless Aggregate Signature Scheme [PDF]

open access: yesIEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2016
AbstractAs an important kind of digital signature, the aggregate signature could aggregate n signatures into a signature and verify those signatures simultaneously. It is suitable for the constrained environment with limited ability of computation and communication. Recently, Chen et al.

Certificateless Short Aggregate Signature Scheme for Mobile Devices

open access: yesIEEE Access, 2019
Today, data is exploding. A large amount of data needs to be processed in a timely and an efficient manner. Aggregate signatures are an efficient and secure way to handle large numbers of digital signatures. In an aggregate signature scheme, n signatures

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
