A new certificateless aggregate signature scheme

Computer Communications, 2009
Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. In this paper, we study aggregate signatures in certificateless public key settings. We first present the notion and security model of certificateless aggregate signature schemes.

On the Security of a Certificateless Aggregate Signature Scheme

IEEE Communications Letters, 2011
Certificateless cryptography eliminates the need of certificates in public key cryptosystems and solves the inherent key escrow problem in identity-based cryptosystems. An aggregate signature scheme is a signature scheme which allows to aggregate n signatures on n distinct messages from n distinct users into a single signature.

Hybrid Aggregate Signature Scheme: A New Type Aggregate Signature Scheme

2009 Second International Conference on Information and Computing Science, 2009
An aggregate signature scheme is a digital signature scheme that supports aggregation: Given n ordinary signatures on n distinct messages from n distinct ordinary signers, it is possible to aggregate all these signatures into a single short signature.

How to Aggregate the CL Signature Scheme

Lecture Notes in Computer Science, 2011
We present an aggregate signature scheme whose public key consists of only two group elements. It is therefore the first sequential aggregate signature scheme with short keys in the standard model. Our construction relies on the Camenisch-Lysyanskaya signature scheme (Crypto 2004) and is provably secure under the LRSW assumption. Moreover, we develop a

MQSAS - A Multivariate Sequential Aggregate Signature Scheme [PDF]

, 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 \(m_1, \dots , m_k\).

Comparing two pairing-based aggregate signature schemes [PDF]

Designs, Codes and Cryptography, 2009
This paper describes detailed security and performance comparisons of two aggregate signature schemes. The first (BGLS), due to \textit{D. Boneh, C. Gentry, B. Lynn} and \textit{H. Shacham} [Eurocrypt 2003, Lect. Notes Comput. Sci. 2656, 416--432 (2003; Zbl 1038.94553)], uses bilinear pairings and has a reductionist security proof assuming the random ...

Certificateless Aggregate Signature Scheme

2010 International Conference on E-Business and E-Government, 2010
This paper puts forward a secure construction of certificateless aggregate signature scheme using bilinear maps. The security of our scheme is based on the infeasibility of the Computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless aggregate signature schemes.

A structured aggregate signature scheme

2010 International Symposium On Information Theory & Its Applications, 2010
In multisignature scheme, verifiying the signing order is sometimes very important. A multisignature scheme in which generated signatures reflect the structure of signers, e.g. signing order, is called structured multisignature scheme and many such schemes have been proposed so far.
