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

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 ...

Signature Bouquets: Immutability for Aggregated/Condensed Signatures [PDF]

open access: yes, 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.

Compact Aggregate Signature from Module-Lattices [PDF]

open access: yes, 2023
We propose the first aggregate signature scheme such that: (1) its security is based on the standard lattice assumptions in the random oracle model; (2) the aggregate signature size is logarithmic; (3) it is not one-time; and (4) it supports non ...

Identity-Based Aggregate Signatures [PDF]

open access: yes, 2006
An aggregate signature is a single short string that convinces any verifier that, for all 1 ≤ i ≤ n, signer Si signed message Mi, where the n signers and n messages may all be distinct. The main motivation of aggregate signatures is compactness. However, while the aggregate signature itself may be compact, aggregate signature verification might require

A Lattice-Based Unordered Aggregate Signature Scheme Based on the Intersection Method

open access: yesIEEE Access, 2018
An aggregate signature turns multi-message multi-authentication into multi-message single-authentication, reducing the required storage space, transmission cost, and number of verification calculations, and is suitable for fast message authentication in ...

Security Analysis of Aggregate signature and Batch verification signature schemes [PDF]

open access: yes, 2009
An identity based signature scheme allows any pair of users to communicate securely and to verify each others signatures without exchanging public key certificates. An aggregate signature scheme is a digital signature scheme which supports aggregation of

Forward-Secure Multi-User Aggregate Signatures Based on zk-SNARKs

open access: yesIEEE 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
