Method and apparatus for secure application execution

A server computer, comprising:

• a processor;
• and
• a computer readable medium coupled to the processor, the computer readable medium comprising code, executable by the processor for implementing a method comprising:
• executing code associated with a payment application running in a first trusted execution environment on the server computer;
• establishing a secure communication channel between the first trusted execution environment executing on a server computer and a second trusted execution environment executing on a first mobile device:
• wherein
• the first mobile device concurrently executes an instance of the payment application in the second trusted execution environment, and
• the first trusted execution environment is a software trusted execution environment and the second trusted execution environment is a secure element, wherein the secure element comprises secure memory and secure hardware computing logic;
• generating a synchronizing event to the second trusted execution environment;
• comparing a first state associated with the payment application executing in the first trusted execution environment and a second state associated with the instance of the payment application executing in the second trusted execution environment using the secure communication channel;
• and
• detecting a difference in the first state and the second state.
