Artificial Noise Aided Secure Transmission for Active RIS-Aided NOMA Networks

open access: yesIEEE Access, 2023
A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper. Assuming that the perfect channel state information is available, we aim to maximize the

On the Shannon Perfect Secrecy Result

open access: yes2020 14th International Conference on Signal Processing and Communication Systems (ICSPCS), 2020
Shannon information theoretic approach to perfect security requires equal number of key bits to the information bits. This fact has been studied for decades and known as "Shannon impossibility result". This paper demonstrates that it is feasible to start with a significantly smaller number of key size than the information bits and generate final keys ...

Online Scheduling for Multi-Hops Wireless Networks With Security Constraints

open access: yesIEEE Access, 2019
We consider wireless multi-hops networks in which each node desires to securely transmit the message. To guarantee secure transmission, we employ an independent randomization encoding strategy to encode the confidential message.

One-round Strongly Secure Key Exchange with Perfect Forward Secrecy and Deniability. [PDF]

open access: yes, 2011
Traditionally, secure one-round key exchange protocols in the PKI setting have either achieved perfect forward secrecy, or forms of deniability, but not both.

Security Analysis in Multicasting over Shadowed Rician and α−μ Fading Channels: A Dual‐hop Hybrid Satellite Terrestrial Relaying Network

open access: yesIET Communications, 2022
In this era of 5G technology, the ever‐increasing demands for high data rates lead researchers to develop hybrid satellite‐terrestrial (HST) networks as a substitution to the conventional cellular terrestrial systems.

An overview of generic tools for information-theoretic secrecy performance analysis over wiretap fading channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2021
Physical layer security (PLS) has been proposed to afford an extra layer of security on top of the conventional cryptographic techniques. Unlike the conventional complexity-based cryptographic techniques at the upper layers, physical layer security ...

Secrecy and Freemasonry

open access: yes, 2022
This chapter discusses the use of secrecy within the Order of Freemasons during its formative period during the eighteenth century. More specifically, it will, first, deal with the function of secrecy in relation to initiation and experiential knowledge.

Perfect and Imperfect Duty: Unpacking Kant's Complex Distinction [PDF]

open access: yes, 2023
I attempt first to disentangle three aspects of Kant’s distinction between perfect and imperfect duty. There is the central distinction between principles of duty contrary to that which is contradictory in conception/consistent in conception but ...
