Hi TLS, Chris Patton and I have produced another revision of our Pseudorandom cTLS draft, which adds a symmetric key to enable a purely pseudorandom bitstream (to an observer who doesn't hold the cTLS template).
Some changes in this draft: * Rebase across changes in cTLS-05, which help to simplify this specification. * Add a Key Derivation step and simplify the tweak construction. * Define an optional Protocol Confusion defense that injects fresh entropy into every message. * Reserve a codepoint for experimental use of a specific underlying cipher (HCTR2) * Describe a reliable procedure for key rotation. * Remove tricky state machine recommendations; recommend authenticating the ClientHello instead. * Numerous other text changes: new "experiment" section, s/STPRP/TSPRP/, discussion of the cTLS extension mechanism, etc. We believe this draft is nearly ready for WG adoption, and will be implementable once the open issues in the cTLS draft are addressed. Please review.
