Unmanned aerial vehicle (UAV) plays an important role in fifth and sixth (5G/6G) communication systems, garnering significant research attention. This paper investigates a dynamic UAV-enabled secure ultra-reliable and low-latency communication (URLLC) system, where a UAV sends confidential data to a mobile device where another UAV cooperatively transmits jamming interference to confuse a potential eavesdropper. The transmission latency constraint, secure communication requirement and dynamic channel characteristics are considered into real-word communication environments. Then, a joint communication transmit power, jamming power, and trajectory optimization approach is proposed to maximize the system secrecy rate, simultaneously guaranteeing the URLLC requirement. To effectively address the non-convex problem, the URLLC constraint is transformed into a data rate constraint to ensure that the optimization problem is more manageable, and then present an efficient solution by employing an alternating approximation and successive convex optimization. Finally, simulation results verify that the presented joint optimization approach substantially outperforms other popular benchmarks in secrecy rate performance.
