Integrated Circuit (IC) supply chain attacks, such as piracy and counterfeiting, is a significant preoccupation for IC and System-on-Chip (SoC) designers. This article makes a practical demonstration of securing a wireless IC against such threats. The case study is an open-source IEEE 802.11 WiFi modem implemented on hardware using a Software Defined Radio (SDR) bladeRF board. The modem is secured with synchronizationbased locking (SyncLock), a state-of-the-art locking scheme for RF transceivers. SyncLock disables the wireless communication between the modem and a WiFi-compliant receiver unless the correct secret key is loaded onto the modem.
