Methods and apparatus for enabling a proximity payment device to generate dynamic data for securely conducting a transaction by emulating a magnetic stripe payment card. In an embodiment, a mobile device processor transmits information to a digital enablement service computer to activate a simulated magnetic stripe payment wallet application stored in the mobile device. The mobile device then receives one or more cryptographic keys, generates an unpredictable number (UN), generates dynamic CVC3 data based on the UN, and then assembles emulated magnetic stripe data. During initiation of a purchase transaction, the mobile device processor transmits the emulated magnetic stripe data to a communications interface associated with a merchant device.

Methods and apparatus for conducting secure magnetic stripe card transactions with a proximity payment device

A mobile computing device has at least one processor and at least one memory together providing a first execution environment and a second execution environment logically isolated from the first execution environment. The following approach is taken to manage data items for an application executing the first execution environment. A trust relationship is established between a trust client in the second execution environment and a remote trusted party and the trust client receives one or more data items from the remote trusted party. On executing the application in the first execution environment, the trust client provides the data items or further data items derived therefrom to the application. Provision of these data items may be conditional upon a user authentication process. A suitable mobile computing device is also described.

Security for mobile applications

A mobile computing device having at least one processor and at least one memory, together providing a first execution environment and a second execution environment logically isolated from the first execution environment, the mobile computing device comprising: a first application executable within the first execution environment; a second trusted application executable within the second execution environment; and a secure communications channel between the first application and the second trusted application, wherein the second trusted application is configured to generate one or more data items and to provide the one or more data items to the first application via the secure communications channel.

Security for mobile payment applications

A portable device configured to enable completion of transactions. The portable device comprises an input mechanism arranged to enable input of an identifier into the portable device, and a selection mechanism arranged to enable the user to select a payment mechanism to be associated with the identifier. The portable device further comprises a communication module arranged to transmit data relating to the identifier and the payment mechanism selection to a remote server. Completion of a subsequent transaction relating to the identifier is enabled using the selected payment mechanism.
