Abstract

A non-contact communication method and a communication device are presented. The communication device includes a trusted execution environment (TEE). A first security application and a second security application are provided in a security element of the communication device. The first security application and an application in the trusted execution environment are communicationally connected by means of a first communication channel. The second security application and a near-field communication (NFC) module provided in the communication device are communicationally connected by means of a second communication channel. The first security application and the second security application are communicationally connected by means of a security channel. Using the non-contact communication method and the communication device, a security channel may be established between NFC and a TEE, which may enable NFC non-contact card reading for a TEE application.
