Abstract
A method and system for hypertext transfer protocol digest authentication through the use of a token issuing entity trusted by both a client and a service provider. The token issuing entity may issue an encrypted token and a token secret to the client. The client may then use the token secret instead of a password for digest authentication, and provided the encrypted token along with the digest authentication response to the service provider. The service provider may decrypt the encrypted token to obtain the token secret, which may then be used for digest authentication with the client.
