Certificateless Short Aggregate Signature Scheme for Mobile Devices
IEEE Access, 2019 Today, data is exploding. A large amount of data needs to be processed in a timely and an efficient manner. Aggregate signatures are an efficient and secure way to handle large numbers of digital signatures. In an aggregate signature scheme, n signatures

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 ...

On security of a Certificateless Aggregate Signature Scheme [PDF]
IACR Cryptol. ePrint Arch., 2012 Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. Recently, Xiong et al.

Anonymous Certificateless Aggregate Signature Scheme in VANETs [PDF]
Jisuanji gongchengVehicle Ad-Hoc Networks(VANETs) serve as the foundational infrastructure for future intelligent traffic systems, which will help ensure the safe operation of vehicles. However, in an open wireless communication mode and complex communication environment,

Insecurity of a certificateless aggregate signature scheme [PDF]
Security and Communication Networks, 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.

Forward-Secure Multi-User Aggregate Signatures Based on zk-SNARKs
IEEE Access, 2021 As a solution to mitigate the key exposure problems in the digital signature, the forward security has been proposed. The forward security guarantees the integrity of the messages generated in the past despite leaks of a current time period secret key by

Generalized Scheme For Fractal Based Digital Signature (GFDS). [PDF]
, 2007 This paper describes a new development in the cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Recently it has been shown that it is possible to have digital signature scheme based on fractal due to the strong connection

Improved Security Proof for the Camenisch-Lysyanskaya Signature-Based Synchronized Aggregate Signature Scheme [PDF]
, 2023 The Camenisch-Lysyanskaya signature scheme in CRYPTO 2004 is a useful building block to construct privacy-preserving schemes such as anonymous credentials, group signatures or ring signatures.
