Abstract:

Strengthening medical sensor data security is crucial due to the vulnerability of wireless transmissions to eavesdropping. This letter focuses on enhancing the security of uplink data transmission. To this end, we propose a novel transmit scheme that leverages uplink rate splitting (RS) and active intelligent reflecting surface (IRS). Uplink RS provides flexible co-channel interference management by splitting user messages. Additionally, active IRS allows us to disrupt the potential eavesdropper through phase adjustment and signal amplification, thereby providing an additional layer of security to the data transmission process. We devise an algorithm for the optimization of key parameters, namely, transmit power allocation, receiver filter, IRS amplification factor matrix, and IRS phase shift matrix. The overarching goal is to maximize the minimum secrecy rate across all users, ensuring equitable security measures. Simulation results demonstrate that our security scheme achieves considerable gains over several existing benchmarks.
