In this embodiment, the bid information processing method further includes the steps of:
s5, generating key pairs corresponding to the first node, the second node, the third node and the fourth node respectively;
and S6, corresponding key pairs are issued to the first node, the second node, the third node and the fourth node.
In this embodiment, each node has its own key pair. Each key pair includes a public key and a private key for asymmetrically encrypting and decrypting information of the corresponding node. The encryption process may be performed by each node or by the body performing steps S1-S4, and the decryption process may be performed by each node or by the body performing steps S1-S4.
The process of encrypting and decrypting with the key pair will be described by taking the encryption and decryption of the BIM ticket in the second node as an example. Referring to fig. 4, a bidder a signs a BIM bid with its own private key a, and then encrypts the BIM bid and signature information using a public key of a bidding platform B. When the bidding platform B, i.e. the main body in steps S1-S4 in this embodiment, receives the BIM bidding document of the bidder a, the BIM bidding document encrypted by the public key of the platform B by the bidder a is decrypted by the private key of the platform, and the decrypted plaintext is obtained, and then the public key of the bidder a is used to sign the signature of the private key of the bidder a. After the asymmetric encryption mode is used, only encrypted information needs to be transmitted in the information transmission process, and a secret key does not need to be transmitted, so that information leakage can be effectively prevented.
Specifically, a key pair corresponding to the first node is used for encrypting and decrypting the bid document acquired from the first node; the key pair corresponding to the second node is used for encrypting and decrypting the BIM standard book acquired from the second node; the key pair corresponding to the third node is used for encrypting and decrypting the evaluation result obtained from the third node; and the key pair corresponding to the fourth node is used for encrypting and decrypting the successful bid result obtained from the fourth node.
In this embodiment, before step S6 is executed, the authenticity of the first node, the second node, the third node, and the fourth node is also checked, and the key pair is issued to the node only if the node is authentic. For example, if the first node is authentic, the key pair is issued to the first node, otherwise, the key pair is not issued to the first node, but is issued to the first node, and whether the key pair is issued to other nodes may not be affected. By checking the authenticity of each node, illegal subjects can be prevented from counterfeiting participants such as tenderers and bidders, and the safety of the tendering and bidding process is further improved.
On the basis of the execution of steps S5 and S6, the following steps are also executed:
s7, in steps S1, S2, S3, S4 and the like, before the bidding information, the review result and/or the medium bid result are broadcasted to the alliance chain, encryption processing is carried out on the bidding information, the review result and/or the medium bid result; specifically, a key pair corresponding to the first node is used for encrypting and decrypting the bid document acquired from the first node; encrypting and decrypting the BIM standard book acquired from the second node by using a key pair corresponding to the second node; encrypting and decrypting a review result obtained from the third node by using a key pair corresponding to the third node; and encrypting and decrypting the successful bid result obtained from the fourth node by using the key pair corresponding to the fourth node.
And S8, recording the encryption processing result.
On the basis of the execution of steps S7 and S8, the following steps are also executed:
s9, when a source tracing request is received, analyzing a target node pointed by the source tracing request; the target node is at least one of a first node, a second node, a third node and a fourth node;
s10, searching a corresponding encryption processing result according to a key pair corresponding to the target node;
s11, determining corresponding bidding information, evaluation results and/or medium bid results according to the searched encryption processing results;
and S12, returning the determined bidding information, evaluation result and/or medium bid result.
The source tracing request may be issued by a supervisor or an operation and maintenance person who is an executing subject of the bid and bid information processing method in this embodiment. The tracing request is directed to one or more target nodes corresponding to the object to be traced and queried by the supervisor, and the target nodes can be a first node, a second node, a third node and a fourth node. For example, when the supervisor needs to query the review result of the third node by tracing, the issued tracing request is directed to the third node, and step S10 is executed, the result of performing the encryption processing recorded in step S8 is searched from the federation chain according to the key pair corresponding to the third node, then step S11 is executed, the key pair used in encryption at that time is used for decryption, the review result is obtained, and step S12 is executed to return to the supervisor.
By executing steps S9-S12, when a traceability request is met, previously recorded information such as bidding information, review results, and bidding results can be obtained from the federation chain, so that traceability queries can be performed, and traceability is easy.
