Embodiment

[0041] The embodiment of the present invention takes the nginx server application as an example to illustrate how to use request / data aggregation to improve the HTTPS application performance of the WebServer.

[0042] First, take nginx as an example to analyze how the upper-layer WebServer application performs SSL data processing on the original data requested through OpenSSL.

[0043] like figure 2 As shown, when nginx sends data, it will call the ngx_output_chain() function to send the cached https data chain, and this function will further call the ngx_ssl_send_chain() function to send the data. The ngx_ssl_send_chain() function will call the ngx_ssl_write() function to use the relevant interface in the OpenSSL library to perform SSL data encryption and verification processing on the original data and send the processed ciphertext data to the client.

[0044] The ngx_ssl_send_chain() function will control the size of the sent data block, as follows:

Abstract

The invention discloses a method for improving the https application performance of WebServer by using request / data aggregation. The method comprises the following steps: performing request aggregation on a plurality of encryption requests of an upper layer WebServer application, issuing the encryption requests to lower layer OpenSSL to perform SSL data processing, and calling a hardware encryption engine to accomplish a plurality of request encryption operations; and with respect to the encryption request with a single data length exceeding the SSL maximum source data length requirements, performing SSL data processing on the OpenSSL layer, performing data aggregation on data blocks, and calling the hardware encryption engine to accomplish a plurality of data block encryption operations. Compared with the manner of calling the hardware encryption engine for multiple times to accomplish the encryption operations of the traditional https request, the method disclosed by the invention has the advantages that after the request / data aggregation is performed, the mode switching cost and context switching cost of hardware calling in the https encryption process can be effectively reduced, the https application performance of WebServer is improved, and the utilization rate of the hardware encryption engine is also improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for improving HTTPS application performance of a Web Server by utilizing request / data aggregation. Background technique [0002] In order to protect the security of sensitive data during transmission, more and more governments, enterprises, and banks have begun to deploy SSL-based https communication. Secure Socket Layer protocol SSL (Secure Socket Layer) is a secure network communication protocol that uses a combination of public key and private key technology. The SSL protocol is a security protocol based on Web applications launched by Netscape. The SSL protocol specifies a mechanism that provides data security layers between application protocols (such as Http, Telenet, NMTP, and FTP) and TCP / IP protocols. It provides data encryption, server authentication, message integrity, and optional client authentication for TCP / IP connections. It is mainly used t...
