Maxim 1-Wire Security Reference Design Protects Spartan-6 FPGA-Based Designs

Maxim 1-Wire security reference design

Maxim Integrated Products introduced a reference design that will protect Xilinx Spartan-6 field-programmable gate arrays (FPGAs). The reference design features security software (from Maxim or Xilinx) and the Maxim DS28E01-100 1-Wire secure memory device. Engineers can easily add a level of design security to products with the Maxim DS28E01-100 1-Wire secure memory device. In the future, the reference design will support Artix-7, Kintex-7, Virtex-7 and the Zynq-7000 FPGA devices.

With Maxim’s 1-Wire secure memories, designers can safeguard FPGA IP from counterfeiters for less than one dollar. 1-Wire secure memories utilize an elegant challenge-and-response authentication sequence that enables FPGAs to differentiate between authorized and cloned environments. This determination either sets the system to normal operation or disables the design, thereby protecting the design investment from copying and cloning.

The DS28E01-100 operates over a single pin. The built-in challenge-and-response SHA-1 authentication scheme prevents unauthorized product builds and safeguards FPGA IP. The reference design enables manufacturers to remotely turn on fee-based software-controlled feature upgrades, without physically altering the installed hardware. The security scheme requires secret keys to be loaded in the FPGA and the 1-Wire secure memory. Maxim’s reference core seamlessly overlays on the Spartan-6 device. It utilizes less than 5% of the logic cell resources and eases the loading of secret keys into the FPGA. Maxim can also preprogram the DS28E01-100 with customer-specified keys prior to delivery.
