保护射频链路的物联网

　　保护射频链路的物联网

　　当我们走向连接我们的运动鞋，所有的冰箱和咖啡机我们的心脏起搏器和门锁、安全等问题的限制访问机密信息的重新重视。这已成为更大的关注，因为我们去无线与我们的物联网（物联网）通信基础设施。

　　本文着眼于现代高速无线链路和安全措施，他们可以随身携带，以确保我们的数据和财产是安全的，防止恶作剧和混乱。所有的部件、数据表、教程、开发系统参考这里可以发现在Digi-Key的网站在线。

　　Network and processor security

　　With wired networks， a tap point must be established to gain access to the raw data streaming over the network. Points outside the collision domain can still gain access if one knows the vitals of the IP address and MAC address of the machine or device you wish to covertly connect to through a layer 2 switch.

　　With gained access to the network， packet sniffing may eventually expose all the nodes directly accessible on the network. Then， bogus packets can be injected onto the network， and services can be accessed and sockets opened， providing you can overcome any security passwords and encryption measures in place （and not every service is encrypted）.
