    • A transmission-based authentication system and method to prevent an unauthorized claimant from tracking a signal are disclosed herein. In one or more embodiments, the method involves transmitting, from at least one transmission source, a plurality of authentication signals. The method further involves receiving, from at least one receiving source, a resultant signal that includes at least two of the authentication signals. Further, the method involves authenticating, with at least one authenticator device, at least one claimant by comparing properties of the resultant signal the claimant receives from the receiving source location(s) to expected properties of the resultant signal that the claimant should receive from the receiving source location(s). The properties that are compared are signal power, doppler shift, time of reception, and/or signal modulation. The transmission source(s) is employed in at least one satellite and/or at least one pseudo-satellite.
    • 本文公开了一种用于防止未授权的索赔人跟踪信号的基于传输的认证系统和方法。 在一个或多个实施例中,该方法包括从至少一个传输源发送多个认证信号。 该方法还包括从至少一个接收源接收包括认证信号中的至少两个的合成信号。 此外,该方法包括通过将索赔人从接收源位置接收到的所得信号的属性与索赔人应从其接收的所得到的信号的期望属性进行比较,至少使用一个认证器装置来认证至少一个请求者 接收源位置。 比较的属性是信号功率,多普勒频移,接收时间和/或信号调制。 至少一个卫星和/或至少一个伪卫星采用发射源。
