In part II, how is the signature bound to the HTTP request URI? I see the method and body, but not the request URI. EHL On 9/23/10 3:39 PM, "Dirk Balfanz" <balfanz@google.com> wrote: Hi guys, sorry it took a while, but here is an updated proposal. It's still in three parts: Part I is about "JSON Tokens" that can be used for all sorts of things, not just OAuth: http://balfanz.github.com/jsontoken-spec/draft-balfanz-jsontoken-00.html Part II is about how to embed an OAuth token and (some parts of) an HTTP request into a JSON Token: http://balfanz.github.com/jsontoken-spec/draft-balfanz-signedoauth2-00.html Part III is how to use signatures instead of client secrets for assertions in OAuth: http://balfanz.github.com/jsontoken-spec/draft-balfanz-clientassertions-00.html Diffs from the last specs are: - JSON Tokens are now just a profile of Magic Signatures, which John Panzer has helpfully extended for this purpose - There was a vulnerability to masquerading attacks in the last proposal, which is addressed in this proposal by adding a data_type parameter that is part of the signature, but _not_ part of the payload. - no more support of X.509 certs - the only supported format for discovered public keys is now the Magic Key format. We'll give people tools (which are quite easy to write) to convert their self-signed or CA-issued certs to magic keys. - The specs are now formatted as I-Ds. Comments, please! Dirk.
