Efficient and provably-secure certificateless sequential aggregate signature scheme

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 ...

Cryptanalysis of a certificateless aggregate signature scheme [PDF]

Security and Communication Networks, 2016
AbstractAn aggregate signature refers to a signature, by which n signatures σ1,...,σn corresponding to n messages m1,...,mn and n users u1,...,un can be transformed into a single short signature . Besides, anyone can be convinced by the single short signature that the n messages m1,...,mn were definitely signed by the n users u1,...,un correspondingly.
