(54)	Method of Securely Transferring Services Between Mobile Devices

(57) A method for securely transferring a service from a first mobile device to a second mobile device, the service being associated with a server configured for facilitating provisioning of services to mobile devices over a wireless communications network. The method includes generating in the first mobile device a shared key, the shared key being generated using a master key unique to the server and to the first mobile device, the master key being accessible by the server and by the first mobile device; and sending said shared key from the first mobile device to the second mobile device using an alternate communication mechanism independent from the server.
