Abstract
To enable formation of secure associations between IP-enabled devices when they have not previously connected, a method is proposed where a declaration of ownership of a target device is made by the subscriber of a originating device and that subscriber giving that declaration is authenticated by means of a SIM card, say. The originating device establishes secure connection to a first server. The target device establishes a secure connection to a second server. Provided the first and second servers can establish a conventional IP-type SA (e.g. using IPSec or TLS), there is a chain of secure associations between the two devices. This chain is then used to build a new secure association between originating device and target Device. The first and second servers thus act as proxies for two devices respectively and negotiate the secure association on their behalf. They then transfer the new secure association information securely to the devices using the existing chain of secure associations.
