AirDrop security iOS devices that support AirDrop use Bluetooth Low Energy (BLE) and Apple-created peer-to-peer Wi-Fi technology to send files and information to nearby devices, including AirDrop-capable Mac computers running OS X 10.11 or later. The Wi-Fi radio is used to communicate directly between devices without using any Internet connection or Wi-Fi Access Point. When a user enables AirDrop, a 2048-bit RSA identity is stored on the device. Additionally, an AirDrop identity hash is created based on the email addresses and phone numbers associated with the user ’ s Apple ID. 这个里面介绍了一些 |

“建立局域网之后利用蓝牙或者热点进行文件传输”你已经把原理说完了

两台电脑用网线直连让其在物理层连通,然后制定应用层协议来定义传输这个动作,最后通过软件调用协议和接口来传输文件。aridrop 的原理类似,应该是通过蓝牙来配对,然后用 wifi 使其在物理层连通,然后使用 apple 的专有协议来传输文件,因为蓝牙传输带宽限制,airdrop 传输速度那么快,基本不可能是通过蓝牙来传的。
