Distributed Nonlinear Polynomial Graph Filter and Its Output Graph Spectrum: Filter Analysis and Design

2021 · IEEE Transactions on Signal Processing

While frequency-domain algorithms have been demonstrated to be powerful for conventional nonlinear signal processing, there is still not much progress in literature dedicated to nonlinear graph signal processing in frequency domain. The difficulties come from …

Toward Secure and Privacy-Preserving Cloud Data Sharing: Online/Offline Multiauthority CP-ABE With Hidden Policy

2022 · IEEE Systems Journal

The continuous development of cloud storage service technology, secure access control, and privacy issues have attracted more and more attention. The previous ciphertext policy attribute-based encryption (CP-ABE) schemes with the function of hidden policy are …
