A New Certificateless Aggregate Signature Scheme [PDF]
Jisuanji gongcheng, 2017 On the basis of the certificateless short signature,this paper proposes a certificateless aggregate signature scheme in resource constrained environment.A signature protocol is initiated by the specified aggregator.The state information including random ...

On the Security of Some Aggregate Signature Schemes [PDF]
Journal of Applied Mathematics, 2012 Aggregate signature scheme proposed by Boneh, Gentry, Lynn, and Shacham allows n signatures on n distinct messages from n distinct users to aggregate a single signature that convince any verifier that n users did indeed sign the n messages, respectively.

Cryptanalysis of a certificateless aggregate signature scheme [PDF]
IACR Cryptol. ePrint Arch., 2016 Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries.

Identity-based key-insulated aggregate signature scheme [PDF]
Journal of King Saud University: Computer and Information Sciences, 2017 Private key exposure can be the most devastating attack on cryptographic schemes; as such exposure leads to the breakage of security of the scheme as a whole. In the real world scenario, this problem is perhaps the biggest threat to cryptography.

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 $\Sigma$ which states the integrity and authenticity of all the messages $m_1, \dots, m_k$. The length of the

Designated verifier aggregate signature scheme based on SM9
网络与信息安全学报Aggregate signatures have been recognized for significantly improving signing efficiency, reducing the computational cost for signers, lowering communication costs, and better protecting the privacy of signers. Currently, many aggregate signature schemes

On the security of a certificateless aggregate signature scheme [PDF]
IACR Cryptol. ePrint Arch., 2013 Aggregate signature can combinensignatures on nmessages fromnusers into a single short signature, and the resulting signature can convince the verifier that thenusers indeed signed the ncorresponding messages.
