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.

A Certificateless Aggregate Arbitrated Signature Scheme for IoT Environments
Sensors, 2020 The Internet of Things (IoT) environment consists of numerous devices. In general, IoT devices communicate with each other to exchange data, or connect to the Internet through a gateway to provide IoT services.

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 ...

Aggregation Signature for Small Object Tracking [PDF]
IEEE Transactions on Image Processing, 2020 Small object tracking becomes an increasingly important task, which however has been largely unexplored in computer vision. The great challenges stem from the facts that: 1) small objects show extreme vague and variable appearances, and 2) they tend to be lost easier as compared to normal-sized ones due to the shaking of lens. In this paper, we propose

Universal Signature Aggregators [PDF]
, 2015 We introduce the concept of universal signature aggregators. In a universal signature aggregator system, a third party, using a set of common reference parameters, can aggregate a collection of signatures produced from any set of signing algorithms (subject to a chosen length constraint) into one short signature whose length is independent of the ...

A New Certificateless Aggregate Signature Scheme [PDF]
Jisuanji gongcheng, 2017 On the basis of the certificateless short signature,this paper proposes a certificateless aggregate signature scheme in resource constrained environment.A signature protocol is initiated by the specified aggregator.The state information including random ...

Unrestricted Aggregate Signatures [PDF]
, 2007 Secure use of the BGLS [1] aggregate signature schemes is restricted to the aggregation of distinct messages (for the basic scheme) or per-signer distinct messages (for the enhanced, prepend-public-key version of the scheme). We argue that these restrictions preclude interesting applications, make usage of the schemes error-prone and are generally ...

Signature Bouquets: Immutability for Aggregated/Condensed Signatures [PDF]
, 2004 Database outsourcing is a popular industry trend which involves organizations delegating their data management needs to an external service provider. Since a service provider is almost never fully trusted, security and privacy of outsourced data are important concerns.
