Random Shifting Intelligent Reflecting Surface for OTP Encrypted Data Transmission

چکیده
In this letter, we propose a novel encrypted data transmission scheme using an intelligent reflecting surface (IRS) to generate secret keys in wireless communication networks. We show that perfectly secure one-time pad (OTP) communications can be established by simple random phase shifting of the IRS elements. To maximize rate, design optimal time slot allocation algorithm for key generation and phases. Moreover, theoretical expression rate is derived based on Poisson point process (PPP) practical scenario when eavesdroppers’ channel state information (CSI) unavailable. Simulation results employing our IRS-based significantly improve performance wide-range gains system parameters.

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
متن کاملPrivate Key based query on encrypted data
Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...

متن کاملEngine-transmission Control for Smooth Shifting Using a Robust Adaptive Scheme with Intelligent Supervisor
In this paper, a robust adaptive control scheme with an intelligent supervisor for vehicle powertrain systems is investigated. The control objectives are to provide smooth shift transients for passenger comfort and to improve components durability. The reaction carrier speed and the turbine speed during the inertia phase are controlled to track their desired speeds. The boundedness of all signa...
