Patent attributes
Techniques for managing secure data transfer, including firmware updates and/or cryptographic keys, may be provided. For example, a portable device may be provided that includes at least a first memory configured to store data associated with secure firmware updates while the device is interacting with a second device. In some examples, a network connection with a third device may be established. The data associated with the firmware update may be received from the third device by utilizing the established network connection. Further, in some examples, the received data may be stored in the first memory only while the first device is interacting with the second device. The portable device may also enable a firmware update of the second device based at least in part on the data stored in the first memory.
