SUNNYVALE, USA: In order to protect Xilinx Spartan-6 field-programmable gate arrays (FPGAs), Maxim Integrated Products has introduced a reference design. The reference design comes with a free security software from Maxim or Xilinx and the Maxim DS28E01-100, a 1-Wire secure memory device.
It also allows manufacturers to remotely turn on fee-based software-controlled feature upgrades, without physically altering the installed hardware. It operates over a single pin, the built-in challenge-and-response SHA-1 authentication scheme in the DS28E01-100 prevents unauthorized product builds and safeguards FPGA IP. Maxim can also preprogram the DS28E01-100 with customer-specified keys prior to delivery.
Secret keys are required to be loaded in the FPGA and the 1-Wire secure memory. Maxim's reference core overlays on the Spartan-6 device; utilizes less than 5 per cent of the logic cell resources and eases the loading of secret keys into the FPGA.
