Design of an Anonymity-Preserving Group Formation Based Authentication Protocol in Global Mobility Networks

IEEE Access, 2018
Remote user authentication without compromising user anonymity is an emerging area in the last few years. In this paper, we propose a new anonymity preserving mobile user authentication scheme for the global mobility networks (GLOMONETs). We also propose

Algorithmic statistics: forty years later [PDF]

, 2017
Algorithmic statistics has two different (and almost orthogonal) motivations. From the philosophical point of view, it tries to formalize how the statistics works and why some statistical models are better than others. After this notion of a "good model"

De-Authentication Using Ambient Light Sensor

IEEE Access
While user authentication happens before initiating or resuming a login session, de-authentication detects the absence of a previously-authenticated user to revoke her currently active login session.

A Mean Quantization Watermarking Scheme for Audio Signals Using Singular-Value Decomposition

IEEE Access, 2019
Recently, research in audio watermarking technology makes it a promising tool for copyright protection of digital audio files in networked environments. In this paper, we propose a new mean quantization based watermarking mechanism for audio based on the

Quantum Kolmogorov Complexity and Quantum Key Distribution

, 2009
We discuss the Bennett-Brassard 1984 (BB84) quantum key distribution protocol in the light of quantum algorithmic information. While Shannon's information theory needs a probability to define a notion of information, algorithmic information theory does ...

Multisource algorithmic information theory [PDF]

, 2017
Multisource information theory is well known in Shannon setting. It studies the possibilities of information transfer through a network with limited capacities. Similar questions could be studied for algorithmic information theory and provide a framework for several known results and interesting questions.

Algorithmic Networks: central time to trigger expected emergent open-endedness

, 2019
This article investigates emergence and complexity in complex systems that can share information on a network. To this end, we use a theoretical approach from information theory, computability theory, and complex networks. One key studied question is how

A secure effective dynamic group password-based authenticated key agreement scheme for the integrated EPR information system

Journal of King Saud University: Computer and Information Sciences, 2016
With the rapid growth of the Internet, a lot of electronic patient records (EPRs) have been developed for e-medicine systems. The security and privacy issues of EPRs are important for the patients in order to understand how the hospitals control the use ...
