Method and device for optimizing data link layer message

Abstract

The invention discloses a method and a device for optimizing a data link layer message. The method comprises the steps of receiving a service request of a user, and acquiring a request message of theservice request, wherein the request message comprises a message header and application data; analyzing the request message, confirming a service type of the service request, and acquiring a data domain list of the application data according to the service type; analyzing the data domain list, and acquiring basic data in the data domain; splicing the basic data according to a preset order according to the service type to acquire complete service data; and processing the complete service data according to a service logic to generate service feedback information, packaging the service feedback information according to the data domain list corresponding to the service type and the preset order and sending the feedback information to a mobile terminal. Through encrypting the data via the security levels of different data domains, the network transmission efficiency of the data is effectively improved, and the workloads for encrypting and decrypting the transmission data in the interactionprocess are reduced.

Description

technical field [0001] The invention relates to the fields of computer networks and computer software, in particular to a method and device for optimizing data link layer messages. Background technique [0002] With the popularization of smart phones and the advent of the Internet era, more and more companies are connecting their core business to the mobile phone platform, which inevitably involves sensitive information such as business data, user order information, and online banking payment information. JD Shujuhui is a mobile app platform that carries JD big data mobile reports. [0003] At present, in terms of ensuring data security at the link layer, secure access and encrypted channels are widely used to establish secure communication channels that provide data confidentiality and integrity. Among them, in order to realize channel security, virtual private network (VPN) is usually adopted in the prior art, namely establishes a private network on the public network, an...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the high cost and inconvenient use of VPN, it cannot be promoted to a large group of users as a conventional method, and VPN also has technical hidden dangers, and occasionally some security holes will be exposed

[0006] 2. After the data is encrypted by using the encryption method, the network transmission efficiency of the data is reduced because the data packet is too large, and both the mobile terminal and the server need to encrypt and decrypt the transmitted data, which increases the burden on the system and is not conducive to users use
