I. Industry Background and Timing Challenges

Party and government agencies handling classified information, as well as internal government networks, are subject to stringent security‑control requirements. Traditional multi‑mode time‑synchronization devices equipped with foreign‑made satellite receivers face risks of time‑signal hijacking and data‑timing‑sequence leakage. Meanwhile, geographically dispersed branch‑office data centers suffer from inconsistent system clocks, resulting in disordered audit‑log sequences and significant challenges in fault‑diagnosis and root‑cause analysis. Conventional equipment lacks independent signal‑protection measures, and the complex electromagnetic environment of modern buildings can easily induce timing drift, making it impossible to meet the rigorous domestic‑production and autonomous‑controllability standards mandated for classified‑information entities.
