Abstract
Mechanisms for establishing forward secrecy during digest access authentication are provided. A method is performed by a client device. The method includes performing digest access authentication with a server device. The digest access authentication includes sending a first request towards the server device for accessing a resource; and receiving a first response. The first response includes a challenge and a public component of an asymmetric key pair for a key exchange with the server device. The digest access authentication includes calculating, using a digest algorithm, a response parameter based at least on the challenge and the public component of the asymmetric key pair; and sending a second request towards the server device for accessing the resource. The second request includes the calculated response parameter. The digest access authentication includes receiving a second response from the server device that indicates successful digest access authentication with the server device.
