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.

Abstract

The invention discloses a satellite network security routing method based on blockchain, and belongs to the technical field of communication and is based on the blockchain technology, and the method comprises the following steps: an initialization stage: registering all legal satellite nodes, packaging registration information into a registration information block, and writing the registration information block into a registration blockchain; in the system operation stage, a source node generates an LSA describing the node, signs the LSA, encapsulates the LSA into an LSA block and writes the LSA block into an LSA blockchain; when the destination node writes in a new LSA block, triggering LSDB update (including adding, replacing or deleting LSA) of the destination node, and then calculatinga route by using an SPF algorithm; and when the system detects that unpredictable interruption occurs in a certain link, the KGC sends a request for updating the credentials to the nodes involved inthe link. In this way, the authenticity and integrity of the LSDB can be guaranteed through the LSA blockchain, and then safe and reliable routing is calculated through the LSDB.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a blockchain-based satellite network security routing method. Background technique [0002] With the continuous expansion of our country's needs in space exploration, emergency communications, military and other fields, it is imminent to build a space-ground integrated network that is deeply integrated with space network, ground Internet and mobile communication network. The key to realizing the space-ground integrated network is to realize the integration of the core layers (that is, the network layer) of various heterogeneous networks, and the routing problem is the top priority. Introducing the IP protocol family into the space-ground integrated network can give full play to the strengths of Internet technology, and build the space-ground integrated network more quickly with lower overhead. [0003] However, due to the openness of the inter-satellite l...
