Hello Alex, Alexandru Petrescu wrote:
Why? It is easy to build a pretty good PRN generator with radio HW. I would say it is much, much, much, much easier than uniqueness guarantee with try and error duplicate detection.I agree. Moreover, there is an RFC talking how to select good entropy sources such that the PRN generator is good.(small embedded devices, such as sensors, can constitute good sources of randomness when sampling the temperature, for example - that RFC says).
Maybe it is time for an "Errata" for the RFC? Of course it depends on the temperature sensitivity of, say, the accelerometer or moisture sensor. And if there are people who are only interested in solutions utilizing such randomizations, maybe they should first propose a new look at the entire IPv6 protocol design for address uniqueness. Maybe the state of the are has progressed sufficiently that the previous discussions have lost some of their validity. In the meantime, can we go forward here? Regards, Charlie P.
