Hi Christian! Thanks for all of the updates. I have a remaining items are described inline. To bring up a new item, there was new text introduced in -06 of Section 5 to which I strongly object. Specifically: "Replacing clear text SNI transmission by an encrypted variant will also thwart

2019-09-26 Thread Daniel Migault
Hi, My understanding of deprecating of TLS1.0 TLS 1.1 is that: a) new software do not use these versions b) existing software stop supporting these versions. I am not sure how likely a new software is to use TLS 1.0 or TLS 1.1 with TLS 1.2 and TLS 1.3 being widely deployed. It seems also a curren

Thanks for raising this discussion John, we have been struggling with this in curdle as well and ipsecme. This is also a topic that I believe would be useful to improve the security. One aspect is that some implementers go to the IANA pages and believe that everything on the pages is acceptable. I

First, I think that we must recognize that the *IETF* does not have the same sectoral powers that 3GPP has. It is entirely appropriate what 3GPP did, and they seem to have learned the lessons they needed. John Mattsson wrote: > How can IETF be more pro-active regarding depreca

2019-09-26 Thread John Mattsson
Hi, Hopefully, we have learned some lessons from the TLS 1.0 and TLS 1.1 deprecation. TLS 1.0 and TLS 1.1 are (to cite Martin Thomson) broken in a myriad subtle ways and should according to me optimally have been deprecated years ago. 3GPP mandated support of TLS 1.2 in Rel-13 (2015) but could
