Abstract

Smart cards using the ISO/IEC 7816 interface are widely used for authentication, ticketing and legacy secure applications. When used with host computers, the smart card typically connects to the host computer over a USB or RS232 smart card reader. This paper presents implementations of an architecture where a Trusted Execution Environment (TrEE) in a smartphone is used as the security foundation for implementing security modules based on the ISO/IEC 7816 smart card standard. The smartphone software emulates both the smart card reader and the card, and thus no new drivers are needed in the host to enable the use of the smart card emulation.
