| contents | Cryptographic Ranging Authentication is here! We present initial results on the Pulsar authenticated ranging service broadcast from space with Pulsar-0 utilizing a recording taken at Xona headquarters in Burlingame, CA. No assumptions pertaining to the ownership or leakage of encryption keys are required. This work discusses the Pulsar watermark design and security analysis. We derive the Pulsar watermark's probabilities of missed detection and false alarm, and we discuss the required receiver processing needed to utilize the Pulsar watermark. We present validation results of the Pulsar watermark utilizing the transmissions from orbit. Lastly, we provide results that demonstrate the spoofing detection efficacy with a spoofing scenario that incorporates the authentic transmissions from orbit. Because we make no assumption about the leakage of symmetric encryption keys, this work provides mathematical justification of the watermark's security, and our July 2025 transmissions from orbit, we claim the world's first authenticated satellite pseudorange from orbit. |
