Abstract
This article resolves an extreme case in physical layer security: an eavesdropper, located near to a source, can spy on the jamming-seed if it is just cryptographically shared. The direct link between the source and destination is even unavailable. The system is proposed to operate in triple transmi
Highlights
Cryptographic security is a popular methodology for avoiding the detection of desire messages by unauthorized users [1]
A single active jammer is selected from multiple nodes to improve the performance of physical-layer security (PLS). This method refers to the singlejammer cooperative jamming (SJJ) approach in this article [3, 37,38,39]
The distributions of hJaS and hJaE are necessary when computing the secrecy rates in the transmission for the binary jamming message. They are independent from the channel state information (CSI), which are essential for calculating the achievable rates, CRa,S and CD,Ra, at the relay and D
Summary
Cryptographic security is a popular methodology for avoiding the detection of desire messages by unauthorized users [1]. Since many relays are able to securely receive the source transmission in the first phase, they can create a distributed beamformer in the second phase This allows them to null the desired transmitting signal at the eavesdropper, or more generally, to maximize the secrecy rate at the legitimate receivers [13, 22, 29]. A single active jammer is selected from multiple nodes to improve the performance of PLS This method refers to the singlejammer cooperative jamming (SJJ) approach in this article [3, 37,38,39]. We use PLS to protect a random binary jamming message generated by a jammer from being wiretapping by the eavesdropper.
