Claim of US Patent No. 9,049,013

1. A method for providing access to a trusted security zone of a mobile device, comprising:
receiving, by an application, trusted service manager validation data from a trusted service manager, wherein the trusted
service manager validation data is uniquely associated with the trusted service manager;

receiving, by the application, a trusted security zone master key;
hashing, by the application, the trusted service manager validation data with the trusted security zone master key to generate
a trusted security zone sub key configured to provide access to a set of one or more trusted security zone containers of the
plurality of trusted security zone containers, wherein the hashing is completed using a one-way secure hash function;

generating, by the application, the trusted security zone sub key based on hashing to access the set of one or more trusted
security zone containers of the trusted security zone;

transmitting at least one message to provision at least in part the set of one or more trusted security zone containers with
the trusted security zone sub key; and
