Pooled communication method between expressway electronic prepaid card and encryption machine

Abstract

The invention discloses a pooling communication method between a highway electronic prepaid card and an encryption machine. The pooling communication method comprises the steps of defining a basic format of return data of the encryption machine, and defining a buffer area through the basic format; establishing a connecting pool object factory, an assembling thread and a reading thread by a server, verifying original data through the connecting pool object factory, putting the verified original data into the buffer area of the encryption machine in a message way through the assembling thread, and returning to an index of the buffer area; reading messages in the buffer area by the encryption machine, writing encrypted data according to the basic format, and transmitting the encrypted data into the buffer area according to the index; and reading the encrypted data in the buffer area by the server, transmitting the encrypted data to a card reader, sending the encrypted data to the highway electronic prepaid card by the card reader after the card reader receives the encrypted data, and calculating by the highway electronic prepaid card according to the encrypted data. According to the pooling communication method disclosed by the invention, the encryption effectiveness is increased, a system resource is prevented from being unused, and the working efficiency is increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a pooled communication method between an expressway electronic prepaid card and an encryption machine. Background technique [0002] The use of highway prepaid cards is already the trend of highway toll collection in the future, making the amount of electronic transaction data more and more large, and the application needs to process thousands of concurrency online in real time, so it is necessary to improve the encryption calculation efficiency and make reasonable use of encryption machine resources. [0003] In the prior art, the interaction between the expressway prepaid card and the encryption machine is usually: establishing a link → sending an encryption instruction → waiting for a specified time → reading from the buffer → closing the connection. If the waiting time of the encryption machine is set too short, it may lead to incomplete reading of data; if the waiting time of the ...

AI Technical Summary

Problems solved by technology

If the waiting time of the encryption machine is set too short, it may lead to incomplete reading of data; if the waiting time of the encryption machine is set long, it will cause a large amount of idle resources, and each encryption needs to be reconnected; if the concurrent business volume suddenly increases Large, may exceed the limit on the number of connections of the encryption machine, and cannot work normally
