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.

Certificateless-based efficient aggregate signature scheme with universal designated verifier [PDF]
Tongxin xuebao, 2015 The security model of the certificateless aggregate signature scheme with universal designated verifier was studied,and then a certificateless aggregate signature scheme with universal designated verifier using bilinear pairings was proposed.In the ...

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.

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.

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.
