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

IEEE 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 ...

A secure Certificateless Aggregate Signature Scheme

International Journal of Security and Its Applications, 2016
Aggregate signatures allow n signatures on n distinct messages from n distinct signers to be aggregated into a single signature that convinces any verifier that n signers do indeed sign the n messages, respectively. The major advantage of utilizing aggregate signatures is to address the security of data and save bandwidth and computations in sensor ...

Improving Bitcoin’s Post-Quantum Transaction Efficiency With a Novel Lattice-Based Aggregate Signature Scheme Based on CRYSTALS-Dilithium and a STARK Protocol

IEEE Access, 2022
This paper proposes a novel lattice-based aggregate signature (LAS) scheme that brings post-quantum security to the Bitcoin system without sacrificing its transaction efficiency. Bitcoin currently employs Elliptic Curve Digital Signature Algorithm (ECDSA)

A short certificateless aggregate signature against coalition attacks.

PLoS ONE, 2018
Certificateless aggregate signature (CLAS) is a crucial cryptosystem. It can not only compress multiple signatures into a short signature, but also ensure the validity of each signature participating in the aggregation by verifying the validity of an ...

Forward Secure Sequential Aggregate Signature Schemes on Lattice

Jisuanji 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

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
