Abstract :
With the continuous development of the space technology, increasing communication between spacecrafts. To ensure the spacecrafts keep a uniform time standard, time synchronization protocol plays an crucial role. Taking account the characteristics of deep-space: poor link quality, limited node computing power, and the GNSS service is unstable, through the improving of IEEE1588 protocol, a autonomous time synchronization protocol for the space environment is presented, which security arrangement is relatively sound, does not depend on the GNSS service - Security Enhanced IEEE1588 for Space (SEIEEE1588).
