Description
Technical Field
The invention relates to the technical field of block chains, in particular to a block chain-based border gateway routing updating method.
Background
The block chain is a decentralized shared database, and data or information stored in the database has the characteristics of being unforgeable, traceable in the whole process, traceable, transparent in public, maintained in a collective mode and the like. Based on these characteristics, the blockchain technology lays a solid trust foundation and creates a reliable cooperation mechanism, so the blockchain technology is generally used for solving the trust problem caused by centralization. According to the different centralization degree of the block chain network, the block chain can be divided into three types as a whole: public, federation, and private chains, in which authorized nodes are allowed to join a network, can view information under permission, are often used in inter-or intra-industry blockchains, referred to as federation or industry chains. And all nodes in the network are held in one organization, which is called a private chain. The federation chain and private chain are also collectively referred to as the license chain, and the public chain is referred to as the non-license chain.
The Border Gateway Protocol BGP (Border Gateway Protocol) is a routing Protocol of an autonomous system running on TCP, is the only network Protocol for handling internet scale levels, and is also the only Protocol capable of properly handling multiple connections between unrelated routing domains. BGP builds on the experience of the external Gateway Protocol (EGP for short). The primary function of the BGP system is to exchange network reachability information with other BGP systems. The network reachability information includes information for listed Autonomous Systems (AS), which effectively constructs a topology map of Autonomous System AS interconnections and thereby clears routing loops, while policy decisions may be implemented at the AS level. The Internet consists of a plurality of AS nodes which are independently operated and maintained. BGP is actually the controller of the packet forwarding paths between these AS nodes, and its security and reliability have a very important impact on whether the entire internet is operating reliably.
In the storage and update of border gateway routing data, existing solutions all utilize a centralized database, and a centralized Public Key Infrastructure (PKI) and some conventional PGP (Pretty Good Privacy) encryption variants as security mechanisms. These solutions are all likely to be compromised in the face of existing hacking techniques and typically use an established database to verify updates to the routing data when updating border gateway routing data, without an appropriate method to verify the data stored in the database. There are certain risk points for this database authentication mechanism of border gateway routers.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
The embodiment is as follows:
referring to fig. 1, fig. 2 and fig. 3, a method for updating a border gateway route based on a block chain includes the steps of:
All interfaces of the IR nodes are in the same area, all the IR nodes in the same area belong to the same virtual peer node (denoted by vPeer), and the IR nodes in the same area have the same ledger copy of the link information;
the ABR nodes are positioned in one or more OSPF areas and are used for connecting the areas to a backbone network; the ABR nodes have topology routing tables of backbone topology and other areas, and the ABR nodes belonging to the same channel (represented by vChannel) have the same ledger copy;
the ER node is responsible for accessing local area networks of enterprises, schools and families to a wide area network and forwarding IP messages between the local area network and the wide area network. The ER node usually executes Routing Information Protocol (RIP) or Open Shortest Path First (OSPF). RIP is a gateway protocol based on shortest distance (hop count), while OSPF is a routing protocol based on shortest path first. The ER router establishes a routing table according to a routing protocol, maintains routes reaching other networks, and has the same ledger copy in the ER router belonging to the same vChannel channel;
the ASBR node is positioned between the OSPF autonomous system and the non-OSPF network, and exchanges the router of the routing information with the router of other protocol. The ASBR router can also run RIP protocol or OSPF protocol, and ASBR routers belonging to the same vChannel channel have the same classified account copy;
BR node refers to a router having at least one interface connected to a backbone area. In some scenarios, the ABR router may also assume the functionality of a BR router and thus be considered a BR router.
The RIR node is responsible for providing IP (IPv 4 and IPv 6) addresses and AS (autonomous system) number distribution for each routing node, and can directly use a national registration mechanism, namely a China Internet information center (CNNIC).
The CA node is a self-established node in the block chain network and is responsible for issuing and managing digital certificates to each routing node. Preferably, the CA node may be replaced by a routing node having CA functionality. In particular embodiments, a CA service may include one or more CA nodes, which, if multiple CA nodes are present, are in a cluster state and have a common access portal. One CA service is typically located in one vChannel channel.
All the nodes except the RIR node need to verify the identity through the CA node to obtain the CA certificate of the node.
The IR node, the ABR node, the ER node, the ASBR node, the RIR node and the CA node are all provided with alliance chain daemon process software, and therefore the block chain network infrastructure is achieved. The federation link daemon software is a communication application program containing real-time message communication and runs on the operating system of the node in the manner of background service.
And 102, implementing all necessary basic components in the blockchain network, and constructing and deploying a decentralized alliance chain platform. To build and deploy a federation chain intelligent contract platform, the following steps are required:
constructing a vPeer node required by a alliance chain intelligent contract platform: and according to the area attribute and the attribution attribute of each router, dividing each IR node, each ABR node, each ER node and each ASBR node into different vPeer nodes. Depending on the complexity of the actual networking scenario, a vPeer node may contain 1 to multiple IR nodes, 0 to multiple ABR nodes, 0 to multiple ER nodes, 0 to multiple ASBR nodes, 0 to multiple BR nodes.
The vPeer node is responsible for managing IR nodes, ABR nodes, ER nodes and ASBR nodes in the vPeer node, and can perform operations such as addition and deletion on the nodes.
Each vPeer node needs to have a wallet component containing multiple signing keys, and the wallet component (denoted as vWallet) of the multiple signing keys is a software service and can be acted by one to multiple ABR nodes or ER nodes or ASBR nodes designated in the vPeer node, and if the number of nodes is multiple, the nodes form a cluster and provide a uniform entrance of the wallet service. The vWallet component realizes the functions of accessing the alliance chain network, managing private keys and addresses, tracking account information of the vPeer node, creating and signing transactions and the like. The multi-signature key means that each vPeer node participating in the blockchain solution of the transaction proposal employs and uses a more secure Multisig wallet to store the multi-signature key. All vPeer nodes must be configured with vWallet components to participate in transaction processing in the vChannel channel.
Each vPeer node needs to have a ledger synchronization service, the ledger synchronization service is served by one to a plurality of designated ABR nodes or ER nodes or ASBR nodes in the vPeer node, and if the nodes are a plurality of nodes, the nodes form a cluster to provide a unified entrance of the ledger synchronization service. Each vPeer node will hold a copy of the ledger that requires the use of a ledger synchronization service to achieve synchronization of ledger data in the vChannel channel.
And 103, constructing channels among the plurality of virtual peer nodes on the alliance chain platform according to the routing rule, and constructing a private chain platform. Wherein:
the routing rule is that whether the vPeer node belongs to the same channel or not is determined according to different routing protocols, such as a RIP protocol or an OSPF protocol, and the like, as well as the distribution of inter-domain routes and the distribution of intra-domain routes.
The vChannel channel is a logic concept, is a communication network which comprises a plurality of vPeer nodes and realizes the private chain function, and realizes data isolation and confidentiality among the vChannel channels. One vChannel channel is a private block chain. One vChannel channel contains a plurality of vcheer nodes, and the same vcheer node may belong to a plurality of vChannel channels, that is, the same vcheer node may participate in transaction processing of a plurality of private block chains. One vChannel channel needs to implement the following component modules:
the CA service components required for constructing the channel, the CA service components in one vChannel channel are acted by one or more ABR nodes or ER nodes or ASBR nodes designated by the first vPeer node in the channel.
The ledger component required for constructing the channel (denoted by vlidger) is composed of two parts: a blockchain and a state database. The blockchain is used to store a history log of routing information, and the record is immutable and only a new record can be added. That is, a block, once added to the chain, cannot be changed any more. In contrast, the state database is used to store the latest routing information, which contains the current values of the key-value pairs of the routing information, which can be added, modified or deleted by the transaction sets in the blockchain, and which all need to be authenticated, confirmed and endorsed.
The ordering service required to build a channel, the ordering service in one vChannel channel (denoted as vOrder) is served by one or more ABR or ER or ASBR nodes specified by the first vPeer node within the channel. If the number of the nodes is multiple, the nodes are in a cluster state, and a public vOrder service access inlet is arranged. The vOrder service is responsible for ordering transactions within a cycle into a block, and then distributing the block to all vPeer nodes in the vChannel channel for verification and validation. To determine the order of transactions, embodiments of transaction ordering are typically implemented using a First Come First served FCFS (First Come First Server) Algorithm or a Deterministic Consensus Algorithm (DCA for short). The period may be a fixed time interval or a fixed data size. The vPeer node receives the block information, carries out verification and confirmation operation, and returns confirmed information once confirmation is carried out. One Channel is managed by the vOrder service.
The member services required to construct a channel, the member services in one vChannel channel are typically served by one or more ABR or ER or ASBR nodes specified by the first vPeer node within the channel, and if there are multiple nodes, these nodes are in the cluster state with a common port for vroder service access. The member service in one vChannel channel realizes the functions of adding, deleting, modifying and inquiring vPeer nodes in the channel.
And step 104, each vPeer node is added into a channel, and a chain code is deployed in the channel.
Because one vChannel channel contains the CA certificate service, and each vceer node added into the channel carries the CA certificate issued by the certificate service, after each vceer node is verified, the whole vChannel channel forms a credible private chain block chain network. Chain code refers to an intelligent contract program deployed on each routing node within a channel that specifies the method of access and modification of transactions. For each routing node, the existing routing information is fixed and rarely changed, and each piece of routing information needing to be updated is regarded as a transaction and submitted to a virtual channel for processing. Each vPeer node in the channel can share the same vLedger account book, namely, each vPeer node can respectively hold a copy of the account book, and the data of the account book is completed by nodes with the account book synchronization function.
After a virtual channel is initialized, a private block chain network formed by the whole channel starts to work, when each vPeer node in the channel receives a routing request, whether the routing request is new routing information or not is judged, and if the routing information can be retrieved from a vLedger account book copy, the request is directly routed and forwarded; if the routing information is not retrieved, the routing information is considered to be a piece of new routing information, the new routing information needs to be verified, and two pieces of information need to be verified logically:
the first part of information includes an AS number and IP prefix information. The AS number and the IP prefix information constitute a mapping table. Wherein, the AS number is distributed by the regional Internet registration management mechanism RIR. The first part verifies the authenticity of each border routing gateway advertising routing IP prefix information. The border gateway routing advertisement information is then passed to the second portion for further validation.
The second part of information comprises the AS number and the AS number directly connected with the AS number. Similarly, the AS numbers and the AS numbers directly connected to the AS numbers form a mapping table, and a many-to-many relationship exists between the AS numbers and the AS numbers. The second part verifies the authenticity of the AS path information of the border gateway route advertisement.
And if any part of the two-part verification is verified to be false or the results of the two verification processes are both false, the announcement information is regarded as the IP prefix hijacking attack of malicious attempt. The announcement information is then logged.
And step 106, completing the processing through the transaction by the verified new routing information.
And after passing the route verification, the new route information is treated as a new transaction while routing the forwarding request, and the transaction is submitted to the vChannel channel.
The vOrder ordering service manages the vChannel channel and distributes the transaction to all vPeer nodes in the channel for processing. Each vPeer node needs to confirm and endorse the transaction and return confirmation and endorsement information to the vroder ordering service. After a period, the vOrder ordering service orders and packages all transaction information which is confirmed and endorsed by the channel vPeer node into a new block, and stores the new block into the vLedger ledger. The ledger synchronization service of each vPeer node synchronizes the data of the new chunk into its own ledger copy.
Although the present invention has been described herein with reference to the illustrated embodiments thereof, which are intended to be preferred embodiments of the present invention, it is to be understood that the invention is not limited thereto, and that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
