这个阶段的token信任形式保证了只有APNs生成它稍后将兑现的令牌，并且它可以向自己保证设备交给它的令牌与它之前的令牌相同为该特定设备提供 - 并且仅适用于该设备.

The form of this phase of token trust ensures that only APNs generates the token which it will later honor, and it can assure itself that a token handed to it by a device is the same token that it previously provisioned for that particular device—and only for that device.

如果用户将备份数据恢复到新设备或重新安装操作系统，设备令牌发生变化.

If the user restores backup data to a new device or reinstalls the operating system, the device token changes.
