I really like this idea. What worries me is the different cases to be examined/solved depending on the source device: host (applications) or router (protocols). And this draft takes into account mostly the first. -- Tassos Ronald Bonica wrote on 20/06/2013 18:55: Folks, Please review this

Re: Next steps for draft-gont-6man-predictable-fragment-id

I believe the doc describes nicely the possible security issues of predictable fragment ids in IPv6. Although the attack scenarios aren't so common/easy as in IPv4 and various operating systems have fixed most of them, i still find urgent to need to standardize this behavior, now that IPv6 is

Wouldn't it be an option to have all applications systems accept as input both formats, but only give as output the new one? i.e. browsers already rewrite URIs. -- Tassos IETF IPv6 working group mailing list ipv6@ietf.org

I personally like the idea of making it a standard, just to have it as a reference for future IPv6 implementations. imho, security related issues should preferably be solved by changing the protocol, unless it's too much work; strict recommendations should then be given. We had a hard time in

Re: Stable privacy addresses (upcoming rev)

I like support the idea, but it's not clear to me the randomness/stableness of the created identifiers. Is there a guarantee, that after rebooting or powering-off/on the host, the produced RID will remain the same if Prefix remains the same? Is there a way to change the secret key in case

Maybe i have misunderstood something, but how does DNS interfere with source address selection? I would go with option A. I would even prefer to limit even more the usage of temporary addresses, but that's another talk. -- Tassos On 27/3/2012 9:41 πμ, JORDI PALET MARTINEZ wrote: Hi Brian,

Hi, I was wondering...wouldn't the flow label be a "better" field for storing this random number? If i remember correctly, early drafts of RPL were using it for loop detection (ok, in a very different way), although in the later ones a new option was chosen.
