高速SPI接口在SIM卡上的应用设计

Design of High-speed SPI Interface Application on SIM Card

通过对当前物联网的安全威胁进行深入分析,发现SIM卡安全方案在实际使用过程中存在的一些问题。鉴于此,结合安全元件(SE)的SPI接口优点,设计了SPI接口应用在SIM卡上的全新方案,详述了该方案的软硬件架构,最后阐述了该方案在实际应用中所具有的优势。

Through an in-depth analysis of current security threats in the Internet of Things(IoT),some issues with SIM card security solutions in practical use are discoverd.In light of this,combined with the advantages of Secure Elements(SE)with SPI interface,a novel approach integrating SPI interface into SIM cards has been devised.A comprehensive elucidation of the software and hardware architecture of this approach has been provided.Furthermore,the advantages of this approach in realworld applications have also been expounded upon.
