Analysis of physical layer secret key capacity in the uniform scattering environment

open access: yesTongxin xuebao, 2016
Physical layer secret key capacity was affected by time difference of channel sounding,mobility of terminals,and additive noise.Effects on the physical layer secret key capacity were quantitatively analyzed in the uniform scattering environment.Based on ...

INNOVATIVE DATA HIDING SECURITY MODEL USING FORENSIC AUDIO VIDEO CRYPTO-STEGANOGRAPHY

open access: yesICTACT Journal on Communication Technology, 2017
Secret information concealing using steganography is simple but to maintain its security, perceptibility, robustness, embedding capacity and good recovery of both cover as well as secret information are the major issues.

Fundamental limits on key rates in device-independent quantum key distribution

open access: yesNew Journal of Physics, 2020
In this paper, we introduce intrinsic non-locality and quantum intrinsic non-locality as quantifiers for Bell non-locality, and we prove that they satisfy certain desirable properties such as faithfulness, convexity, and monotonicity under local ...

Common Randomness and Secret Key Capacities of Two-Way Channels [PDF]

open access: yes, 2011
Common Randomness Generation (CRG) and Secret Key Establishment (SKE) are fundamental primitives in information theory and cryptography. We study these two problems over the two-way communication channel model, introduced by Shannon. In this model, the common randomness (CK) capacity is defined as the maximum number of random bits per channel use that ...

Experimental quantum key distribution beyond the repeaterless secret key capacity [PDF]

open access: yesNature Photonics, 2019
Quantum communications promise to revolutionise the way information is exchanged and protected. Unlike their classical counterpart, they are based on dim optical pulses that cannot be amplified by conventional optical repeaters. Consequently they are heavily impaired by propagation channel losses, which confine their transmission rate and range below a

Cooperative Jamming-Based Physical-Layer Group Secret and Private Key Generation

open access: yesEntropy
This paper explores physical layer group key generation in wireless relay networks with a star topology. In this setup, the relay node plays the role of either a trusted or untrusted central node, while one legitimate node (Alice) acts as the reference ...

An Enhanced Approach of Image Steganographic Using Discrete Shearlet Transform and Secret Sharing

open access: yesمجلة بغداد للعلوم, 2022
Recently, the internet has made the users able to transmit the digital media in the easiest manner. In spite of this facility of the internet, this may lead to several threats that are concerned with confidentiality of transferred media contents such as ...

Asymmetry in Skipping Enhances Viability Against Control Input Noise

open access: yesAdvanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

Radiotherapy Enhances the Oncolytic Efficacy of the Novel Oncolytic Herpesvirus VG161 and Amplifies Its Antitumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
RT promotes VG161 replication in BC and its immunostimulatory transgenes expression, which is mediated by the upregulation of GADD34 and HVEM caused by RT. The combination therapy with VG161 and RT increases the abundances of tumor‐infiltrating lymphocytes and elicits potent systemic antitumor immunity, thereby effectively inhibiting local tumors and ...
