	abstract = {In this paper, we analyze the physical layer security of a jamming-aided wireless communication system assisted by a reconfigurable intelligent surface (RIS). Our setup consists of a source node communicating with a destination node with the help of a RIS, and under the presence of a malicious passive eavesdropper attempting to overhear the genuine transmission. Furthermore, an external cooperative jammer is incorporated to reinforce the system{\textquoteright}s secrecy by broadcasting an artificial noise to disrupt the eavesdropper; such a noise can be removed at the destination. Finally, we assume that the tunable RIS phases based on the channel estimates are subject to quantization errors. By virtue of the well-adopted Gamma and Exponential distributions approximations, an approximate expression for the system{\textquoteright}s intercept probability (IP) is derived in terms of the main setup parameters. The results show that the greater the number of reflective elements (REs) and jamming power, the better the secrecy, while the number of quantization bits has less impact when exceeding 3 bits. In particular, an IP of 10-3 can be reached with 50 REs even when the legitimate link{\textquoteright}s average signal-to-noise ratio (SNR) is 15 dB below the wiretap channel{\textquoteright}s average SNR. Monte Carlo simulations endorse the derived analytical results. {\textcopyright} 2022 IEEE.},

	abstract = {This paper investigates the performance of maximum-ratio combining (MRC) linear receivers in a massive multiple-input multiple-output (mMIMO) uplink communication system, that in terms of their signal-to-interference-plus-noise ratio (SINR) operating under independent flat Weibull multipath fading channels (WFCs). Based on a tight approximate probability density function (PDF) expression of the signal-to-noise ratio at the considered receiver output, we derive new accurate closed-form expressions of PDF, outage probability (OP) for mMIMO employing MRC technique. The results show high accuracy for significant values of K{\texttimes}Nr mMIMO system at high/low transmission power and severity fading parameters as well. Indeed, the greater K{\texttimes}Nr, the better the PDF{\textquoteright}s accuracy, therefore, the better is the OP. Numerical outcomes have been assessed by using Mathematica Software to show up our results. {\textcopyright} 2021 IEEE.},

	abstract = {Cooperative transmission in vehicular ad-hoc networks (VANET) seems to be an efficient solution when no direct transmission between the source and the destination is possible. However, secure reception of the message at the destination through not necessarily honest relays remains a crucial problem to solve in VANET. In this paper, we propose a trust cooperative transmission protocol for multiple-hops broadcast in VANET which selects among all relays only the best ones minimizing a function of finite number of metrics. Our proposed protocol uses cryptography to ensure a confidential communication between the source and the destination. As the vehicle broadcast the safety message thus, the primitive of cryptography which can be used is Ciphertext-policy attribute based encryption (CP-ABE), because this primitive provides an encrypted access control mechanism for broadcasting messages. {\textcopyright} 2016 IEEE.},
