New direction for open NFC trusted mobile applications: The MOBISIM project

This poster presents new perspectives for open and trusted mobile applications. The Near Field Communication (NFC) radio interface is widely available for smartphones. It is usually involved in payments, access control, and transport services. We describe an open experimental platform, developed by the MOBISIM project. The prototype provides contactless payments in legacy frameworks. It comprises the following elements. A mobile phone supporting a Host Card Emulation (HCE) interface and including the OpenMobileAPI library. A SIM card integrating a TLS/DTLS stack. A mobile application, issued by the service provider, that drives HCE and SIM. The EMV payment application is split between the mobile application storing and processing static data, and a remote server hosting cryptographic resources whose access is secured via the TLS channel managed by the SIM.
