Re: [TLS] New Internet Draft: The qpack_static_table_version TLS extension

2023-09-26 Thread Lucas Pardue
Hi Rory, I echo Watson and Martin, lets discuss this in the HTTP WG. As for a very brief technical response. In general I'm supportive of the idea of more agility of the static table but I think my motivations would be different than the ones behind this proposal. For me, I'd like more domain-spe

[TLS] New approach to timing attacks against RSA key exchange - the Marvin Attack
