Oscilloquartz将伽利略OSNMA集成至授时平台防欺骗

The growing dependence of telecommunications, energy, financial and computing infrastructure on GNSS timing is creating a corresponding security problem: the signals used to establish time can be manipulated. Spoofed or replayed GNSS signals can cause a receiver to generate an erroneous time reference, potentially propagating errors in systems that depend on precise synchronization. Switzerland’s Oscilloquartz is addressing this vulnerability by adding Galileo Open Service Navigation Message Authentication (OSNMA) to several of its timing and synchronization platforms. The company has incorporated the capability into its OSA5412, OSA5422 and OSA5430/40 platforms through integration of u-blox’s ZED-F9T high-accuracy timing module. Readers know OSNMA provides a means of establishing whether Galileo navigation data received by a timing system is genuine. The civil authentication service became operational in July 2025, providing users with cryptographic authentication of navigation messages transmitted by the constellation. For timing applications, authentication adds a security layer that conventional GNSS reception does not provide. A receiver can determine that the navigation information it is processing originated from Galileo rather than simply accepting a signal because it appears to have the appropriate characteristics. Authentication in the timing chain Oscilloquartz is combining that capability with its existing Syncjack technology, which is designed to identify record-and-replay attacks, or meaconing. The two approaches address different aspects of the threat: OSNMA authenticates the navigation message, while Syncjack can help identify suspicious behavior associated with manipulated or replayed signals. The integration can be introduced through firmware upgrades, avoiding the need for operators to replace existing hardware or interrupt service. That could lower the barrier to deploying authenticated GNSS timing in operational networks. The applications extend well beyond conventional navigation. Cellular networks require tightly controlled timing for synchronization, while electrical grids, financial systems and data centers rely on accurate timestamps and stable frequency references. The adoption also illustrates a broader shift we have seen in the role of Galileo within the European PNT security ecosystem. OSNMA was initially introduced as a service for authenticating navigation information, but its integration into commercial timing equipment dem…
