Abstract:
Techniques for enhancing the security of storing sensitive information or a token on a communication device may include sending a request for the sensitive information or token. The communication device may receive a session key encrypted with a hash value derived from user authentication data that authenticates the user of the communication device, and the sensitive information or token encrypted with the session key. The session key encrypted with the hash value, and the sensitive information or token encrypted with the session key can be stored in a memory of the communication device.
