Abstract
A method of accessing local applications when roaming on a NFC mobile device may include creating a first partition and a second partition on a secure element (SE) of a subscriber identification module (SIM) of a near field communication (NFC) enabled device. The home TSM separates the first partition and the second partition by public key encryption. The home TSM generates cryptographic keys in response to a request by a roaming TSM for access to the second partition of the SIM. Following the exchange of security keys, the home TSM delegates to the roaming TSM access to the second partition of the SIM.
