Security analysis of the unrestricted identity-based aggregate signature scheme. [PDF]
PLoS ONE, 2015 Aggregate signatures allow anyone to combine different signatures signed by different signers on different messages into a short signature. An ideal aggregate signature scheme is an identity-based aggregate signature (IBAS) scheme that supports full ...

Efficient unrestricted identity-based aggregate signature scheme. [PDF]
PLoS ONE, 2014 An aggregate signature scheme allows anyone to compress multiple individual signatures from various users into a single compact signature. The main objective of such a scheme is to reduce the costs on storage, communication and computation.

A short certificateless aggregate signature against coalition attacks. [PDF]
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 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.

Logarithmic-Size Post-Quantum Linkable Ring Signatures Based on Aggregation Operations [PDF]
EntropyLinkable ring signatures are a type of ring signature scheme that can protect the anonymity of signers while allowing the public to verify whether the same signer has signed the same message multiple times.

On Key Substitution Attacks Against Aggregate Signatures and Multi-Signatures
IEEE AccessThe most fundamental security requirement for signature schemes is unforgeability, which guarantees that no one can create a valid signature on a message without the secret signing key.
