SensorGuard-RV protects sensor data on RISC-V devices
Original title: SensorGuard-RV: Sensor-to-Register Data Protection for Resource-Constrained RISC-V Devices
SensorGuard-RV delivers protected samples to registers in 51.9 μs using hardware encryption.
Embedded systems risk sensor data interception or tampering. SensorGuard-RV routes samples directly to processor registers without trusting drivers or buses. Implemented on NEORV32 with ADXL362 accelerometer on FPGA, it uses Ascon authenticated encryption and adds minimal overhead while improving throughput.
- Protected sample reaches register in 51.9 μs
- Sustains 19,015 transactions/s
- Adds 3,155 LUTs and 2,215 registers
- Preserves 100 MHz clock frequency
