MQSAS - A Multivariate Sequential Aggregate Signature Scheme [PDF]
Lecture Notes in Computer Science, 2016 (Sequential) Aggregate signature schemes enable a group of users \(u_1, \dots , u_k\) with messages \(m_1, \dots , m_k\) to produce a single signature \(\varSigma \) which states the integrity and authenticity of all the messages \(m_1, \dots , m_k\).

A Practical Lattice-Based Sequential Aggregate Signature
Lecture Notes in Computer Science, 2019 In this work, we construct a lattice-based efficient Sequential Aggregate Signature (SAS) scheme that is provably secure in standard ideal cipher model with some slight changes. This framework is inspired by the scheme of Gentry et al. at PKC 2018 which presented trapdoor-permutation-based sequential aggregate signatures.

Certificateless Ordered Sequential Aggregate Signature Scheme
2011 Third International Conference on Intelligent Networking and Collaborative Systems, 2011 Ordered sequential aggregate signature scheme is a signature scheme in which each signer for a group signs an individual document, and guarantees both of the validity of the document and the signing order. Many ordered sequential aggregate signature schemes are ID-based scheme and inherit an intrinsic insider problem, called key escrow problem, of the ...

Secure and Traceable Attribute-Based Sequential Aggregate Signature
Lecture Notes in Computer Science, 2021 Attribute-based signatures allow a signer with a set of attributes to anonymously sign a message about some signature policy. However, in the environments that require accountability and preventing abuse, the anonymity revocation function is vital important and necessary. In order to meet the requirements that multiple different authorized participants

Identity-Based Sequential Aggregate Signature from RSA
2009 Fourth ChinaGrid Annual Conference, 2009 Sequential aggregate signature (SAS) schemes allow multiple signers to sequentially produce a short signature of different messages and also allow signers to attest to these messages as well as the order in which they signed. Identity-based signature (IBS) schemes allow a signer to sign a message, in which the signature can be verified by his identity.

Attribute Based Sequential Aggregate Signature
2013 International Conference on Cloud Computing and Big Data, 2013 Attribute based signature (ABS) scheme is an important cryptographic primitive which provides a powerful way for user to control their privacy. However, the computational and storage cost of ABS is reasonable when the number of users involved in the system is huge.
