step S243: when the node K with the same resource mark is not found during searching, the type of resource is the first time of adding into the system, and then the routing information of the node K is put into a routing ring node information table.
8. The intelligent search system based on information system integration according to claim 7, wherein: the step S3 further includes the steps of:
step S31: before the node is inserted into a specific resource routing ring, the node needs to be positioned to the resource routing ring according to the resource type;
step S32: when the known resource type is a plaintext M, randomly selecting a value V in a plaintext interval [ Mmin, Mmax ], and calculating a resource mark S and an attribute value interval [ MIN, MAX ] of the resource mark by using a homomorphic encryption mechanism;
step S33: calculating a ciphertext attribute value FHV by using a random function in the resource attribute value interval, and then calculating an object identifier O of the attribute value according to a set algorithm;
step S34: and routing to a node K by using a routing algorithm of the peer-to-peer cloud system, and checking whether a resource marked as S exists in the node K.
9. The intelligent search system based on information system integration according to claim 8, wherein: the step S34 further includes the steps of:
step S341: when the resource marked as S in the K node exists, finishing the search and returning to success, and when the resource marked as S in the K node does not exist, randomly generating a new ciphertext attribute value FHV again in the attribute interval to search again;
step S342: and ending the search algorithm until the search of the resources of the type returns successfully or the search times exceed the limit and return fails.
10. The intelligent search system based on information system integration according to claim 9, wherein: the step S4 further includes the steps of:
step S41: after the resources are issued in a resource routing ring mode, in the peer-to-peer cloud system, nodes with the same resources form a resource routing ring by storing routing information marked by the same resources;
step S42: when the keyword interval searched by the user is [ V1, V2], if the keyword is a plaintext, calculating ciphertext intervals [ FHV1, FHV2] by using a homomorphic encryption mechanism, and calculating a resource tag S;
step S43: and searching a node N for storing the type of resources through a resource positioning algorithm according to the resource marking value S, and comparing search interval keywords in the resource routing ring by taking the node N as an initial node.
