novena_entropy

This is an experimental HW system for the Novena platform.

The purpose of the system is to debug, evaluate and qualify the avalanche Cryptech entropy providers for the Novena platform with the Xilinx Spartan-6 FPGA. The entropy providers being tested are the noise based entropy provider and the ring oscillator based entropy provider.

The following cores are used in the system: - core/coretest, the test command parser

  • core/i2c, the serial interface that connects the system to the Novena CPU.

  • core/avalanche_entropy, the entropy provider that is driven by an external noise source.

  • core/rosc_entropy, the entropy provider driven by jitter between 32 independently running ring oscillators in the FPGA.

Test SW is available in src/sw
