Security andTruss in the Baseband
With growing concerns about network security, the FPGA offers a unique advantage: its configuration bitstream can be encrypted and authenticated, preventing unauthorized modification of the baseband hardware. This hardware root of trust is essential for protecting the radio from tampering and for securing secure boot processes in Open RAN equipment. Modern FPGAs support AES-256 bitstream encryption and SHA-3 authentication, ensuring that only authorized configuration data can be loaded into the device. This protects against physical attacks where an adversary might attempt to load a malicious bitstream that could intercept or manipulate radio traffic.
