Abstract
Techniques for enhancing the security of a communication device may include providing an application agent and a transaction application that executes on a communication device. The application agent may receive, from the application, a cryptogram key generated by a remote computer, and store the cryptogram key on the communication device. When the application agent receives a request to conduct a transaction from the application, the application agent may generate a transaction cryptogram using the cryptogram key, and provides the transaction cryptogram to an access device.
