Efficient and provably-secure certificateless sequential aggregate signature scheme [PDF]
Tongxin xuebao, 2022 Aiming at the problem that current schemes mostly let the latter signer to verify the multiple signatures of the previous signer, and the message is signed and then passed to the next signer, leading to the efficiency problem of long overall signature ...

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 ...

On the Security of a Certificateless Aggregate Signature Scheme [PDF]
International Journal of Advancements in Computing Technology, 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.

Insecurity of a Certificateless Aggregate Signature Scheme [PDF]
IEICE 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.

Forward Secure Lattice-Based Sequential Aggregate Signature Schemes in Stan-dard Model
Jisuanji kexue yu tansuo, 2021 In the forward secure sequential aggregate (FssAgg) signature scheme, the signer combines signatures generated in different intervals under different secret keys incrementally and sequentially in a layered “onion-like” fashion with the first signature ...

Practical Short Signature Batch Verification [PDF]
, 2009 In many applications, it is desirable to work with digital signatures that are short, and yet where many messages from different signers be verified very quickly. RSA signatures satisfy the latter condition, but are generally thousands of bits in length.
