Optimum Relay Scheme in a Secure Two-Hop Amplify and Forward Cooperative Communication System
Ghadamali Bagherikaram, Konstantinos N. Plataniotis
A MIMO secure two-hop wireless communication system is considered in this paper. In this model, there are no direct links between the source-destination and the source-eavesdropper…
Secure Hybrid Digital-Analog Coding With Side Information at the Receiver
Ghadamali Bagherikaram, Konstantinos N. Plataniotis
In this work, the problem of transmitting an i.i.d Gaussian source over an i.i.d Gaussian wiretap channel with an i.i.d Gaussian side information available at the intended receiver…
Secure Joint Source-Channel Coding With Side Information
Ghadamali Bagherikaram, Konstantinos N. Plataniotis
In this work, the problem of transmitting an i.i.d Gaussian source over an i.i.d Gaussian wiretap channel with an i.i.d Gaussian side information is considered. The intended receiv…
On the Secure Degrees-of-Freedom of the Multiple-Access-Channel
Ghadamali Bagherikaram, Abolfazl S. Motahari, Amir K. Khandani
A -user secure Gaussian Multiple-Access-Channel (MAC) with an external eavesdropper is considered in this paper. An achievable rate region is established for the secure discrete…
On the Secure DoF of the Single-Antenna MAC
Ghadamali Bagherikaram, Abolfazl S. Motahari, Amir K. Khandani
A new achievability rate region for the secure discrete memoryless Multiple-Access-Channel (MAC) is presented. Thereafter, a novel secure coding scheme is proposed to achieve a pos…
Secrecy Rate Region of the Broadcast Channel with an Eavesdropper
Ghadamali Bagherikaram, Abolfazl S. Motahari, Amir K. Khandani
In this paper, we consider a scenario where a source node wishes to broadcast two confidential messages to two receivers, while a wire-tapper also receives the transmitted signal.…
