Title: HCE Solution For Offline Transactions
Authors: Punchihewa, D.H.T.
Issue Date: 28-Jul-2021
Abstract: Electronic smart card payment are widely used in transport payment systems these days. During last few years most of transport operators have started to introduce smart card payments. Most of the existing systems accept offline transactions. The key feature of smart card payments is storing data in the smart card. Smart card has embedded integrated circuits which can be used to store data securely and to communicate with terminal application via Near-field communication(NFC). The objective of this research is to create a proof of concept(PoC) to replace existing smart cards by Android HCE application. HCE assumes that any data stored on a android device is vulnerable and therefore restricts the storage of sensitive data to host or “cloud” databases. Usually HCE provides more simple and less secure way for payment transaction. So this research focus on increasing the security of the stored data in mobile application and make payments without connecting to back-end services. I have selected Desfire EV1 as smart card to emulate on android device. Desfire EV1 card has complex file structure and security features with compare to other available smart cards. Server system is used to increase the security of emulated virtual card in Android device. HSM simulator is used to store keys and perform crypto operations. We present full design and implementation of the system architecture and security architecture involving with the project. We also provide a comparison of implemented system with the existing smart card solution. Android base terminal was used to simulate this bus ticketing terminal application. This terminal application uses Desfire AV2 SAM to store master keys of the virtual card and perform crypto operations to prepare PICC APDUs.
