ChaosKey To Production

Keith Packard http://linux.conf.au/schedule/present... ChaosKey is a true random number generator. It contains a noise source and an ARM SoC with a USB interface and provides about 1MB/s of random bits, suitable for replenishing the meager supply available in a typical Linux machine. All of the hardware designs, firmware, linux drivers and other software are available under share-alike licenses. The hardware and software development tools are also free software. Development of ChaosKey started almost three years ago, and the first batch of 1000 that we've built was received in August and made available for sale. This presentation will describe the hardware and software design process, including the many dead ends and hardware iterations symptomatic of a software engineer's approach to hardware design. Portions of the hardware were adapted from other free hardware projects showing how ideas from share-alike software licenses can be successful in the world of hardware too.
