Issue #2472 has been updated by dillon. Description updated Status changed from New to Closed % Done changed from 0 to 100
Closing. Made modifications as requested and also adjusted /dev/urandom and the sysctl random to use IBAA (which is what /dev/random uses), so they all use IBAA now and nothing uses L15. These changes will make it into the 3.8.1 roll on Monday June 16th 2014. In the near future we will run with two independent algorithms and xor their streams together. We are discussing this now. 3.8.1 will likely roll with just IBAA but if we get the second algorithm in place in the next few weeks we will MFC it to the release branch. -Matt ---------------------------------------- Bug #2472: L15 update http://bugs.dragonflybsd.org/issues/2472#change-12081 * Author: robin.carey1 * Status: Closed * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- Dear DragonFlyBSD-bugs, I have made a couple of updates to the L15 algorithm since it was imported into the DragonFlyBSD tree as the CSPRNG used for /dev/urandom (/sys/kern/kern_nrandom.c). The first update (output indirection) is purely security related (and a slight decrease in performance), so I doubt you'd be interested in that. However, the second update (which I implemented last night) increases performance and also is a minor security improvement. I would have thought this would be of interest to DragonFly, especially considering that the (random) system thread on DragonFly calls NANOUP_EVENT() approximately once every second. Both updates are available in source form (C++): http://www.leopard.uk.com/L15 And the corresponding documentation (regarding both updates) is also available from the above URL. If you have an questions or don't understand what I'm talking about feel free to contact me by E-mail. -- Sincerely, Robin Carey BSc -- You have received this notification because you have either subscribed to it, or are involved in it.
