This paper focuses on full-duplex secure communication of wireless IMD systems, proposing a new protector that is compatible with existing unsecure systems. This new protector is an externally worn jacket and therefore called a security jacket. Because some advanced sensors are placed on the jacket to provide physical layer security. Randomly multi-jamming with a great number of sensors is applied when IMD transmission occurs with the jamming extraction and maximum ratio combining (MRC) reception simultaneously. When reception by IMD is performed, a randomized spoofing-based transmit beamforming technique is applied. This protector also supports higher power efficiency and longer battery life.en10.1109/ACCESS.2019.2910029info:eu-repo/semantics/openAccessTransmit beamformingphysical layer security for IMDsspoofing-based transmit beamformingwireless implantable medical deviceswireless wearable sensorsArticle75535855366WOS:000467639900001Q1Q1
