简介:【摘要】随着物联网嵌入式技术和智能终端的发展,一种用于短距离非接触式射频识别的近场通信(Near Field Communication,简称NFC)被广泛应用到我们的日常生活中,而安全监控是一个重要的应用领域,也是物联网卡应用最广泛的领域,如:为了提升社区安防、街道安防、施工工地安防等监控功能,相对应的NFC应用场景就是门禁系统、智能猫眼、可视对讲系统、防盗报警器、红外探测器等等,然而,随之也带来了很多安全隐患问题,NFC设备在通信时易发生被嗅探分析、身份伪造、恶意篡改等问题,其安全性也越来越受到相关开发者的重视,对于此类人群普遍使用的信息安全测试工具,快速稳定高效才是有力的生产力工具。为此,本文研究设计了一种高效侦测NFC设备通信秘钥的设备,对该设备的总计设计方案、硬件电路设计及其制作方法进行了简要介绍,为相应部门如何高效侦测NFC设备安全性提供了一种新的途径和参考。
