Hi, Doesn’t it depend on whether it would be easier to do this select* or deal with multiple validations in the same message? No one’s said that exactly afaik, but I haven’t watched the meeting yet. thanks, Rob * in the recent past, the stuff I’ve worked on has made this easy, but I agree they’r

[TLS] Transcript ambiguity in cTLS

2022-07-25 Thread Ben Schwartz
I noticed some confusion today about the topic of ambiguous transcripts in cTLS. My claim was not that any single cTLS profile has an ambiguous transcript. If such a thing were true, I believe that would be a bug in the cTLS specification. Instead, I was trying to highlight the concern of "profi

[TLS] client attestation type in draft-fossati-tls-attestation

2022-07-25 Thread yangpeng...@chinamobile.com
Hi all, First of all, I think this document is very interesting and useful in scenarios like communication between TEE and client. In my point of view, I think the protocol could support other customized attestation formats for a wide range of use. For example, maybe a integrity measurement res

[TLS] Extensibility in SCVP draft

Take this: struct { PathValidationType path_validation_type; select (path_validation_type) { case scvp: SCVPValidationRequest; } request; } PathValidationRequest; enum { scvp(1), (255) } PathValidationType; This adds a layer of extensibility that doesn't do a lot. Please
