    • A method and an apparatus for data transmission between a contactless front element and a security element are provided. The method includes: the contactless front element transparently transmits first data obtained from a contactless identification device to the security element through a single wire connection; the security element processes the first data to generate second data; the contactless front element transparently transmits the second data obtained from the security element through the single wire connection to the contactless identification device. Compared with the prior art, the method can transmit the contactless data in real time between the contactless front element and the security element. Thus the security element can directly respond instructions sent by a proximity coupling device during simulating Proximity Integrated Circuit Card, so that the contactless front element becomes a transparent transport channel, the time order compatibility problem can be avoided, and the safety problem can be surmounted.
    • 提供了一种用于非接触式前部元件和安全元件之间的数据传输的方法和装置。 该方法包括:非接触式前部元件通过单线连接将从非接触识别装置获得的第一数据透明地发送到安全元件; 所述安全元件处理所述第一数据以产生第二数据; 非接触式前部元件通过单线连接将从安全元件获得的第二数据透明地发送到非接触式识别装置。 与现有技术相比,该方法可以在非接触式前置元件和安全元件之间实时传输非接触式数据。 因此,在模拟接近集成电路卡期间,安全元件可以直接响应由邻近耦合装置发送的指令,使得非接触式前部元件变为透明传输通道,可以避免时间顺序兼容性问题,并且可以克服安全问题。
