A Novel Security Scheme Supported by Certificateless Digital Signature and Blockchain in Named Data Networking

IET Information Security, Volume 2024, Issue 1, 2024.
Named Data Networking (NDN) is a promising network architecture that differs from the traditional TCP/IP network, as it focuses on data rather than the host. A new secure model is required to provide the data‐oriented trust instead of the host‐oriented trust.

(t, n) threshold secret sharing scheme without SDC

Tongxin xuebao, 2006
By means of the intractability of ellipse curve discrete logarithm problem（ECDLP）,a（t,n） secret sharing threshold scheme based on ellipse curve cryptography was proposed.Generally speaking,there are two kinds of threshold schemes: a threshold scheme with

A Note on an ECDLP-based PoW Model.

, 2020
We lay the foundations for a blockchain scheme, whose consensus is reached via a proof-of-work algorithm based on the solution of consecutive discrete logarithm problems over the point group of elliptic curves. In the considered architecture, the curves are pseudorandomly determined by block creators, chosen to be cryptographically secure and changed ...

TriVer: a lightweight and client-verifiable secure aggregation with dropout tolerance for federated learning

Journal of King Saud University: Computer and Information Sciences
Federated learning relies on a central server to aggregate client updates, making secure aggregation (SA) essential for privacy protection. Masking-based SA schemes dominate large-scale deployments due to their low overhead, yet they face a fundamental ...
