MAXREFDES44#: Secure Authentication Design with 1-Wire ECDSA and Xilinx Zynq SoC (MAXREFDES44)
The MAXREFDES44# is a 1-Wire®-based authentication reference design, built to protect IP and authenticate peripherals to Xilinx Zynq™ FPGAs. Using the provided example code, the system executes an asymmetric challenge-response sequence with the DS28E35 to ensure the authenticity of a module, peripheral, or subsystem. The DS28E35 communicates on Maxim Integrated’s 1-Wire bus. The MAXREFDES44# is equipped with a Pmod™ connector for immediate testing using an Avnet MicroZed™ board. The simplicity of this design enables rapid adoption into any peripheral requiring the heightened security provided by the asymmetric ECDSA algorithm.
