Technical Field
The invention belongs to the technical field of data exchange, and particularly relates to a data exchange system based on a bidirectional message queue.
Background
In recent years, networking and data sharing have been a trend of informatization of various industries. The need for information exchange between different business systems within a unit and between business systems of different units is increasing more and more frequently. In this context, data exchange platforms for implementing data exchange between service systems have been developed.
The data exchange platform can provide a method for integrating and cooperating data of the definition and configuration part, can calculate a data route matched with the datagram characteristic according to the datagram characteristic for each data exchange request, and sequentially calls corresponding data processing services according to the definition sequence of the data route, thereby realizing data and information sharing among different databases.
However, for the existing data exchange platform, the two data interaction modules perform information transmission based on the established one-way message queue, which makes it impossible to implement full-duplex communication between two service systems corresponding to the two data interaction modules, and further results in a low data exchange rate of the data exchange platform and easily causes backlog of data requests. On the other hand, the priority of the data request is not considered when the existing data exchange platform feeds back the data request, and when the backlog of the data request to be processed is large, the data exchange platform still feeds back the data request according to the sequence of receiving the data request, so that some data requests with higher priority can not be fed back later.

Detailed Description
Preferred embodiments of the present invention will be described in more detail below. While the following describes preferred embodiments of the present invention, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example (b): the Message Digest (Message Digest) is also called a Digital Digest (Digital Digest). Which is a fixed length value uniquely corresponding to a message or text, is generated by a one-way Hash encryption function acting on the message. If the message has changed en route, the recipient knows whether the message has changed by comparing the newly generated digest of the received message with the original digest. The message digest thus ensures the integrity of the message. The message digest uses a one-way Hash function to "digest" the plaintext to be encrypted into a string of 128-bit ciphertext, which is also called a digital fingerprint (Finger Print). It has fixed length, and different plain text digests are cipher texts, and its result is always different, and the digests of identical plain texts must be identical. The collision resistance of the HASH function is such that if a segment of plaintext changes slightly, even if only one letter of the segment is altered, a different value will be produced by the HASH algorithm. The unidirectionality of the HASH algorithm makes it computationally impossible to find two different input messages with the same HASH value. The hash value of the data, i.e., the message digest, can verify the integrity of the data. The property of the hash function that can generate different values for different inputs makes it impossible to find two inputs with the same hash value. Therefore, if two documents are hash-converted to the same value, it is confirmed that they are the same document. So, when it is desired to effectively compare two blocks of data, their hash values can be compared. For example, the hash value before and after sending the mail can be compared to verify whether the mail is modified during delivery.
The digital signature is data obtained by encrypting the digital fingerprint by a sender through a private key of the sender, wherein the two processes of asymmetric key encryption and digital signature are included, and the digital signature can be used for encrypting the data and simultaneously can be used for verifying the validity of the identity of the sender by a receiver. When the digital signature is adopted, the receiver can use the public key of the sender to unlock the digital signature to obtain the digital fingerprint.
The digital fingerprint is also called a message abstract and refers to data obtained after a sender calculates plaintext information through a HASH algorithm. When the digital fingerprint is adopted, a sender sends the digital fingerprint (which is subjected to digital signature) generated by carrying out HASH operation on a plaintext by a home terminal and a ciphertext generated by encrypting the plaintext by adopting an opposite terminal public key to a receiver, the receiver uses the same HASH algorithm to carry out matching on the data fingerprint generated by calculating the plaintext and the received digital fingerprint, and if the data fingerprint is consistent, the plaintext information can be determined not to be tampered.
