Embodiment 1
[0087] Such as figure 1 and figure 2 As shown, those skilled in the art can implement the present invention as a block chain-based satellite network routing method, which is based on block chain technology and maintains a tamper-proof and traceable LSA block chain, before the routing node in the domain performs LSDB update (including adding, deleting and replacing LSA), the LSA entry in the LSDB can be verified by querying the LSA block chain. If the verification passes, the LSDB will be updated; if the verification fails, the LSDB will not be updated. This can ensure the authenticity and integrity of the LSDB, and then calculate safe and reliable routes through the LSDB.
