Problems solved by technology

[0005] As the data is repeatedly transmitted between the processor of the host and the accelerator card, the bandwidth overhead of the processor and the memory increases, and at the same time, the data transmission brings a certain delay, which offsets the benefits brought by the accelerator card, resulting in the acceleration The acceleration effect brought by the card is not significant

Abstract

The invention provides a message transmission method and device. The method is applied to first equipment provided with an acceleration card and a processor. According to the method, bandwidth overhead and data delay caused by transmission can be reduced, the method comprises the steps that an acceleration card receives a first transmission layer control protocol (TCP) message from a processor, to-be-encrypted data are carried in the first TCP message, and the to-be-encrypted data belong to secure socket layer (SSL) data; encryption information used for encrypting the first TCP message is determined according to a pre-acquired mapping relation, the mapping relation indicates a corresponding relation between an identifier of a TCP connection bearing the SSL data and encryption and decryption information, and the encryption information at least comprises an encryption algorithm and an encryption parameter; to-be-encrypted data carried in the first TCP message is encrypted according to the encryption information to obtain a second TCP message, the second TCP message is the encrypted first TCP message; And the second TCP message is sent to the second device.

Description

technical field [0001] The present application relates to the field of communications, and more specifically, to a method and device for transmitting messages. Background technique [0002] With the rapid development of computer technology, the network has become an important guarantee for social development. How to ensure that data is not leaked is an important reason affecting the development of the network, and end-to-end data encryption is conducive to preventing information from being leaked. [0003] Secure sockets layer (secure sockets layer, SSL) / transport layer security (transport layer security, TLS) technology is an encryption technology widely used at present, and can be widely applied to Internet communications. For example, when accessing a website with an SSL-based Hypertext Transfer Protocol (Hyper Text Transfer Protocol over SSL, HTTPS), it is all based on the SSL protocol. The encryption and decryption operations of SSL data can be completed by a processo...
