Abstract:
1. A method of logging out a user from an authority service node within a cloud services environment, the method comprising the steps of: A) providing one or more cloud services to a particular user who is logged into the cloud services environment through a processing node communicatively coupled to the authority service node, wherein providing the one or more cloud services comprises verifying a logged in state of the user, wherein verifying the logged in state of the user comprises comparing (1) a first token received in connection with a request from the user for a cloud service from a requested domain with (2) a second token generated using a cryptographic key and the requested domain; B) receiving a logout request for the particular user; and C) replacing the cryptographic key associated with the particular user at the processing node with a second cryptographic key responsive to the logout request, wherein the second cryptographic key prevents the processing node from properly comparing the first token with the second token thereby preventing access by the processing node.
