Abstract
A method of maintaining a secure relationship between a client device and a server is described. The client device receives a first challenge from the server and determines and provides a first response to the first challenge. A cookie is established associated with the secure relationship. This cookie is shared between the client and the server. To establish the secure relationship in a later interaction, the client provides the cookie to the server. The server then provides both the first challenge and a second challenge, to which the client determines a first response and a second response. The client then provides a composite response from which the first response and the second response are derivable by the server, allowing the server to be assured that the secure relationship exists. Each challenge uses a challenge function adapted to provide a fingerprint of the client device. Methods at both client and server, and suitably configured client and server, are also described.
