Secrecy Performance Analysis of Artificial-Noise-Aided Spatial Modulation in the Presence of Imperfect CSI

open access: yesIEEE Access, 2018
The security of information over wireless channels has always been an important aspect of wireless communication research. In this paper, the secrecy performance of a spatial modulated system with an artificial noise is investigated over the Rayleigh ...

Symmetric-key Authenticated Key Exchange (SAKE) with Perfect Forward Secrecy [PDF]

open access: yes, 2019
Key exchange protocols in the asymmetric-key setting are known to provide stronger security properties than protocols in symmetric-key cryptography. In particular, they can provide perfect forward secrecy, as illustrated by key exchange protocols based ...

Asymptotic Perfect Secrecy in Distributed Estimation for Large Sensor Networks

open access: yes, 2017
This paper considers asymptotic perfect secrecy and asymptotic perfect estimation in distributed estimation for large sensor networks under threat of an eavesdropper, which has access to all sensor outputs.

Towards a provably secure DoS-Resilient key exchange protocol with perfect forward secrecy [PDF]

open access: yes, 2011
Just Fast Keying (JFK) is a simple, efficient and secure key exchange protocol proposed by Aiello et al. (ACM TISSEC, 2004). JFK is well known for its novel design features, notably its resistance to denial-of-service (DoS) attacks.

Security-Enhanced Vehicle-to-Roadside Unit Authentication Scheme for Internet of Vehicles

open access: yesMathematics
Secure real-time data interaction between vehicles and transportation infrastructure, such as RSUs (V2R), can achieve intelligent and safe driving, as well as efficient travel services, in Internet of Vehicles (IoV), a secure and efficient V2R ...

Matrix Power Function Based Block Cipher Operating in CBC Mode

open access: yesMathematics, 2022
In our previous study, we proposed a perfectly secure Shannon cipher based on the so-called matrix power function. There we also introduced a concept of single round symmetric encryption, i.e., we used the matrix power function together with some rather ...

Perfect secrecy systems immune to spoofing attacks [PDF]

open access: yesInternational Journal of Information Security, 2012
We present novel perfect secrecy systems that provide immunity to spoofing attacks under equiprobable source probability distributions. On the theoretical side, relying on an existence result for $t$-designs by Teirlinck, our construction method constructively generates systems that can reach an arbitrary high level of security.

Disenrollment with perfect forward secrecy in threshold schemes [PDF]

open access: yesIEEE Transactions on Information Theory, 2006
In this correspondence, we propose a new model for threshold schemes with disenrollment capability (TSDC), to address the scenarios in which the ability of a coalition to construct future shared secrets is prohibited. Compared to existing TSDC models, our model provides forward secrecy by adding a constraint that the broadcast from the dealer is ...

Distributed Matching Algorithms: Maximizing Secrecy in the Presence of Untrusted Relay [PDF]

open access: yesRadioengineering, 2017
In this paper, we propose a secrecy sum-rate maximization based matching algorithm between primary transmitters and secondary cooperative jammers in the presence of an eavesdropper.

Perfect secrecy cryptosystem with nonuniform distribution of keys

open access: yesTongxin xuebao, 2018
More strictly mathematical concepts of infinite perfect secrecy and random “one-time pad” cryptosystem in theory were presented,and the whole secure communication system was divided into two stages:design of a basic cryptosystem and one of its ...
