Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] An SSL proxy method with MIME data type filtering technology, the method adds a policy filter module at both ends of the SSL client proxy and the SSL server proxy and establishes a non-encrypted data line between the SSL client and the SSL server channel; wherein the policy filtering module analyzes the MIME data type in the HTTP request to determine whether the transmitted information needs SSL security protection, and the method includes an SSL client proxy workflow and an SSL server proxy workflow, and the The interactive transmission of data is completed between the two processes.

[0034] Such as figure 1 As shown, the SSL client proxy workflow includes the following steps:

[0035] a. The user sends an HTTPS request through the client's local browser;

[0036] b. The client's local browser proxy captures HTTPS requests, establi...

Abstract

The present invention discloses a SSL commission method with MIME data type filter technique in the field of computer software and information safety software technology. In current SSL commission system the brower can be used for making SSL safety protection of all the informations, but for information sensing by using it can not only make individual protection, so that it reduces the data transmission performance of SSL safety commission. Said invention utilizes the analysis of MIME data type in the HTTP reguest, and utilizes the filter strategy configuration of SSL brower commission and server commission and adopts clear transmission of information having no need of safety protection so as to greatly raise data transmission performance of SSL safety commission.

Description

technical field [0001] The invention relates to the fields of computer software and information security software, in particular to an SSL proxy method with MIME data type filtering technology. Background technique [0002] The SSL (Secure Socket Layer Protocol) protocol is an encrypted transmission technology protocol. By specifying a symmetric key for the symmetric encryption technology, an encrypted channel is established, and the information passing through this channel is encrypted. The SSL proxy is the information encryption and forwarding software that implements the SSL protocol. The existing SSL security proxy system is mainly divided into two aspects: the server side providing WEB services and the user client side composed of remote login users, business partners and remote branches. Its working principle is: [0003] 1. When the browser establishes an SSL connection request with the remote server, its HTTPS request is captured by...
