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 ...

From Rerandomizability to Sequential Aggregation: Efficient Signature Schemes Based on SXDH Assumption [PDF]
Lecture Notes in Computer Science, 2020 An aggregate signature allows one to generate a short aggregate of signatures from different signers on different messages. A sequential aggregate signature (SeqAS) scheme allows the signers to aggregate their individual signatures in a sequential manner.

Extraction Security of Sequential Aggregate Signatures
Chinese Journal of Electronics, 2021 Aggregate signature schemes enable anyone to compress many signatures into one. Besides the unforgeability of aggregate signature, another property called aggregate extraction sometimes is useful.

Sequential aggregate signatures with short public keys without random oracles [PDF]
Theoretical Computer Science, 2015 The notion of aggregate signature has been motivated by applications and it enables any user to compress different signatures signed by different signers on different messages into a short signature.

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.

Forward Secure Sequential Aggregate Signature Schemes on Lattice
Jisuanji kexue yu tansuo, 2021 The forward secure sequential aggregate (Fss-Agg) signature has the advantages of forward secure signature and the sequential aggregate signature at the same time. Since its proposal in 2007, it has been widely applied in many application scenarios, such

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 ...
