Aggregation Signature for Small Object Tracking [PDF]

open access: yesIEEE 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

Forward Secure Lattice-Based Sequential Aggregate Signature Schemes in Stan-dard Model

open access: yesJisuanji 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 ...

Pointcheval-Sanders Signature-Based Synchronized Aggregate Signature

open access: yes, 2023
Synchronized aggregate signature is a special type of signature that all signers have a synchronized time period and allows aggregating signatures which are generated in the same period. This signature has a wide range of applications for systems that have a natural reporting period such as log and sensor data, or blockchain protocol.

Universal Signature Aggregators [PDF]

open access: yes, 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 ...

Unrestricted Aggregate Signatures [PDF]

open access: yes, 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 ...
