ABSTRACT
With the increase in the number of satellites, the security time synchronization protocol between satellites and servers on the ground increasingly important. But, the time protocol that existing in space lack of security protections. Also, SEIEEE1588's author has gathered the advantage of both NTP and IEEE1588 protocol raise a security enhanced IEEE1588 protocol for deep-space environment (SEIEEE1588). The protocol just using symmetric encryption algorithm, does not consider the strong identity authentication, reasonable key update and other security measures. This paper on the basis of IEEE1588 and SEIEEE1588, research the time synchronization mechanism of IEEE1588, the security measures of SEIEEE1588 and safe data transmission protocols. At last, redesign the time synchronization protocol that contains identity authentication that use digital certificate to verify the identity of both sides, asymmetric encryption algorithm and reasonable key updates, to suitable the deep-space that is poor link quality, limited node computing power.
