    • A system, method, and apparatus for the authentication of the physical location of a target node are disclosed herein. In one or more embodiments, the authentication of the target node's physical location is achieved by using ping ranging measurements obtained from the amount of time that elapses during ping messages being sent between the target node and at least one trusted node with a known physical location. The physical location of the trusted node(s) is obtained by using satellite geolocation techniques. The accuracy of the ranging measurements may be improved upon by using pre-coordination and/or priority determination of the ping messages being sent between the target node and the trusted node(s). In at least one embodiment, the ping messages are sent by dedicated ping response hardware that is associated with the target node and/or the trusted node(s). In some embodiments, the ping messages include a pseudo random code bit sequence.
    • 本文公开了用于认证目标节点的物理位置的系统,方法和装置。 在一个或多个实施例中,通过使用从在目标节点和具有已知物理位置的至少一个可信节点之间发送的ping消息期间经过的时间量获得的ping测距测量来实现目标节点的物理位置的认证。 通过使用卫星地理定位技术获得可信节点的物理位置。 通过使用在目标节点和可信节点之间发送的ping消息的预协调和/或优先级确定来改进测距测量的准确性。 在至少一个实施例中,ping消息由与目标节点和/或可信节点相关联的专用ping响应硬件发送。 在一些实施例中,ping消息包括伪随机码比特序列。
