1. OpenID Connect
1.1 Encrypted request objects
OpenID authentication requests can be optionally signed, or signed and encrypted, by packing their parameters in a JWT.
Support for signed OpenID authentication requests was added in v6.0 of the Connect2id server.
Encrypted OpenID authentication requests keep the request parameters confidential from the end-user and browser.
2. OAuth 2.0
2.1 OAuth Incremental Authorisation
OAuth 2.0 authorisation requests that include every scope the client might ever need can result in over-scoped authorisation and a bad end-user consent experience. The draft-ietf-oauth-incremental-authz spec enhances the OAuth 2.0 authorisation protocol by adding incremental authorisation, the ability to request specific authorization scopes as needed, when they’re needed, removing the requirement to request every possible scope that might be needed upfront.
2.2 OAuth 2.0 Token Exchange
The OAuth working group is drafting a protocol for a lightweight HTTP- and JSON-based Security Token Service (STS) by defining how to request and obtain security tokens from OAuth 2.0 authorization servers, including security tokens employing impersonation and delegation. See draft-ietf-oauth-token-exchange.
2.3 OAuth 2.0 Device Flow
The OAuth working group is also developing a special flow tailored for browserless and input constrained devices, such as smart TVs, media consoles and printers. This authorisation request is performed on a secondary device, such as a smartphone. Communication between the constrained device and the user’s secondary device need not required. See draft-ietf-oauth-device-flow-05
3. JOSE / JWT
3.1 Ed25519 digital signatures
Benchmarks with the new Curve25519 revealed that digital signing with it is 22x faster than the current ECDSA signing with P-256. Verification was also faster, at 14x. The Ed25519 JWS algorithm will speed up issue and processing of ID tokens and self-contained (JWT-encoded) access tokens.
