Embodiment Construction

[0038] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0039] First, briefly explain the working process of SSL, refer to figure 1, assuming that the two hosts in a communication process are client and server respectively. The SSL acceleration device receives data packets from the client or server, and the SSL acceleration device processes the data packets according to the protocol mode set with the client or server. If the agreement between the two parties is set in cipher text mode (that is, https protocol), the SSL acceleration device needs to encrypt the received data message before sending it out; if the agreement between the two parties is set in plain text mode (that is, http protocol), then The SSL acceleration device needs to decrypt the received data pack...

Abstract

The present invention provides an SSL asynchronous proxy method based on stream processing, which is applied to an SSL acceleration device. The method includes the steps: a) the SSL acceleration device receives a data message sent by a host, and the data message is a plaintext data message or an encrypted data message; b) If the current message is a plaintext data message, extract the plaintext data and encrypt it to generate an encrypted data block; c) If the current message is a ciphertext data message, extract the encrypted data block of the message The ciphertext data is decrypted to generate plaintext data. Through the technical scheme of the invention, the response time to the application program is shortened, and then the efficiency of the CPU of the SSL acceleration device is improved as a whole.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an SSL asynchronous agent method based on stream processing. Background technique [0002] In order to protect the security of sensitive data during transmission, more and more enterprises, governments, and banks have begun to deploy SSL (Secure Sockets Layer, Secure Sockets Layer) communication. SSL is a security and confidentiality protocol proposed by Netscape, which constructs a secure channel between the browser and the Web server for data transmission. The SSL protocol is located between the TCP / IP protocol and various application layer protocols, providing encrypted data channels for applications. . SSL is a security protocol provided on the basis of the Internet to ensure the privacy of data transmitted on the Internet. It enables communication between client / server applications to be protected from eavesdropping by attackers. [0003] In order to ensure the s...
