    Abstract: Methods and systems are described that secure application data being maintained in transient data buffers that are located in a memory that is freely accessible to other components, regardless as to whether those components have permission to access the application data. The system includes an application processor, a memory having a portion configured as a transient data buffer, a hardware unit, and a secure processor. The hardware unit accesses the transient data buffer during execution of an application at the application processor. The secure processor is configured to manage encryption of the transient data buffer as part of giving the hardware unit access to the transient data buffer.

    Abstract: A multi-purpose smartcard is disclosed. a computer-implemented method of controlling a smartcard. The smartcard can include a near-field communication (NFC) system. The NFC system can be configured to communicate with remote computing systems. The smartcard can include one or more computing chips embedded in the smartcard. The smartcard receives, from a provisioning computing system accessible to a user, a transaction type indicator and transaction data, the transaction type indicator indicating a particular transaction type from a plurality of potential transaction types. The smartcard stores, in the one or more computer-readable media of the one or more computing chips, the transaction data. The smartcard communicates, using the NFC communication system and in accordance with the transaction type, the transaction data to an authentication computing system.
