Identity-Based Revocation From Subset Difference Methods Under Simple Assumptions

open access: yesIEEE Access, 2019
Identity-based revocation (IBR) is a specific kind of broadcast encryption that can effectively send ciphertext to a set of receivers. In IBR, a ciphertext is associated with a set of revoked users instead of a set of receivers and the maximum number of ...

Sigma function solution of the initial value problem for Somos 5 sequences [PDF]

open access: yes, 2007
The Somos 5 sequences are a family of sequences defined by a fifth order bilinear recurrence relation with constant coefficients. For particular choices of coefficients and initial data, integer sequences arise.

On the Design of Fine Grained Access Control With User Authentication Scheme for Telecare Medicine Information Systems

open access: yesIEEE Access, 2017
A telecare medicine information system (TMIS) for health-care delivery service requires information exchange among multiple IT systems, where different types of users with different access privileges are involved. In TMIS, users generally communicate via

Orthosymmetric bilinear map on Riesz spaces [PDF]

open access: yesCommentationes Mathematicae Universitatis Carolinae, 2015
Summary: Let \(E\) be a Riesz space, \(F\) a Hausdorff topological vector space (t.v.s.). We prove, under a certain separation condition, that any orthosymmetric bilinear map \(T:E\times E\rightarrow F\) is automatically symmetric. This generalizes in certain way an earlier result by \textit{F. Ben Amor} [Positivity 14, No.

Eigenvectors of the Discrete Fourier Transform Based on the Bilinear Transform

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Determining orthonormal eigenvectors of the DFT matrix, which is closer to the samples of Hermite-Gaussian functions, is crucial in the definition of the discrete fractional Fourier transform.

Topological Centers and Factorization of Certain Module Actions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
Let $A$ be a Banach algebra and $X$ be a Banach $A$-bimodule with the left and right module actions $pi_ell: Atimes Xrightarrow X$ and $pi_r: Xtimes Arightarrow X$, respectively. In this paper, we  study  the topological centers of the left module action

Hyperspectral Nonlinear Unmixing by Using Plug-and-Play Prior for Abundance Maps

open access: yesRemote Sensing, 2020
Spectral unmixing (SU) aims at decomposing the mixed pixel into basic components, called endmembers with corresponding abundance fractions. Linear mixing model (LMM) and nonlinear mixing models (NLMMs) are two main classes to solve the SU.
