 JSON Web Token is a fairly new standard which can be used for token-based authentication. Unlike the built-in TokenAuthentication scheme, JWT Authentication doesn't need to use a database to validate a token. [Blimp][blimp] maintains the [djangorestframework-jwt][djangorestframework-jwt] package which provides a JWT Authentication class as well as a mechanism for clients to obtain a JWT given the username and password.
 
+## Hawk HTTP Authentication
+
+The [HawkREST][hawkrest] library builds on the [Mohawk][mohawk] library to let you work with [Hawk][hawk] signed requests and responses in your API. [Hawk][hawk] lets two parties securely communicate with each other using messages signed by a shared key. It is based on [HTTP MAC access authentication][mac] (which was based on parts of [OAuth 1.0][oauth-1.0a]).
+
+## HTTP Signature Authentication
+
+HTTP Signature (currently a [IETF draft][http-signature-ietf-draft]) provides a way to achieve origin authentication and message integrity for HTTP messages. Similar to [Amazon's HTTP Signature scheme][amazon-http-signature], used by many of its services, it permits stateless, per-request authentication. [Elvio Toccalino][etoccalino] maintains the [djangorestframework-httpsignature][djangorestframework-httpsignature] package which provides an easy to use HTTP Signature Authentication mechanism.
