Abstract: A mobile communications device includes a near field communications (NFC) port and processor. The processor executes a trusted application within a trusted execution environment (TEE) for processing sensitive data. Additionally, the processor executes a NFC driver within the TEE for providing a secure channel between the trusted application and the NFC port such that sensitive data being exchanged across the secure channel are inaccessible to other processes being executed by the processor.

Abstract: Methods, electronic devices, and systems for exchanging encrypted information. A method for exchanging encrypted information by an electronic device includes generating one or more device certificates and one or more device public private key pairs. The one or more device certificates are signed using a device unique private key that is pre-stored on the electronic device. The method also includes sending the one or more device certificates to a server of a token service provider (TSP). The method further includes receiving one or more TSP certificates from the TSP server. The method includes identifying one or more TSP public keys of the TSP server based on the one or more received TSP certificates. Additionally, the method includes transmitting a message including the information encrypted based on the one or more identified TSP public keys and a signature of the electronic device.

Abstract: An apparatus and method for securing a personal identification number (PIN) on a mobile device are provided. The method may include receiving a request for the PIN from a secure element on the mobile device, instantiating a trusted user interface (TUI), collecting the PIN via the TUI, and securely transmitting the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).
