Encryption everywhere is good.
You mean Evers public information should be encrypted? I.e. Radio vor TV? Can't see the "feature", sorry...
have you looked at your cable TV lately? Or your DAB radio?
Once a connection is encrypted and certificate-protectedhole class
of worries can be removed from the threat models; having fewer things
to
worry about is great when designing protocol stacks.
This is correct by theory in many, but not all cases and not in practice.
A https geht takes up to multiple times of energy and computing resources. I prefer efficiency even in protocols - resources should be user for real (not only theoretic) added value.
See the Great Cannon attack. Allowing in-flight modification of
resources (which using HTTP is) is not just a theoretical danger to
yourself, it's a practical danger to anyone on the Net.
But since you're not convinced by the language of the IESG note, me
repeating it won't make you more convinced. Sorry 'bout that.
Browser HTTP-SSL/TLS isn't "just encrypt and forget" as long as you really unterstand the whole infrastruture and setup in practice including their implications today - and not in theory only. This is not like and comparable with the migration from telnet to SSH and even not with SMTP TLS/SSL...
It's more comparable with the transition from bang-path addresses to DNS
notation, yes.
And getting a faked x509 i.e. for mitm is more a question of some money and/or third party CA securitiy and not at first of secure crypto algos or similiar.
And blocking plaintext http is no feature - it is at max a lack of...
Not a part of this proposal.
Sorry...
best regards,
Niels.
