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

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 ...

Pointcheval-Sanders Signature-Based Synchronized Aggregate Signature
, 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]
, 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 ...

Keeping Authorities "Honest or Bust" with Decentralized Witness Cosigning [PDF]
, 2016 The secret keys of critical network authorities - such as time, name, certificate, and software update services - represent high-value targets for hackers, criminals, and spy agencies wishing to use these keys secretly to compromise other hosts.
