Abstract

The invention discloses a method, a system and a device of information transmission for solving the problem existing in the prior art of comparatively poor security of information transmission. The method of information transmission, provided by the invention, includes the following steps that: after receiving an access request from a client, a server generates a virtual input device according to information of an actual input device of the client. Keys in the same positions of the virtual input device and the actual input device are corresponding with each other and at least a part of the keys which are in the same positions and used for users to input security information, represent different information; the server displays the virtual input device to the users by the client and receives the security information inputted by the user according to the virtual input device displayed by the client; the server transfers the received security information to obtain the security information according to the corresponding relationship between keys of the virtual input device and the actual input device. The method, the system and the device of the invention are used for the information transmission between the client and the server.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, system and device. Background technique [0002] In e-commerce applications with relatively high security requirements, in order to ensure that the password entered by the user is not captured by others, two methods are usually used: one is to use SSL (Security Socket Layer) encryption channel, and the other is to install it on the client. Encryption controls. [0003] Among them, SSL is a security protocol that constructs a secure channel between the browser and the web server for data transmission. SSL runs above the TCP / IP layer and below the application layer to provide encrypted data for the application. aisle. SSL adopts encryption algorithms such as RC4, MD5, and RSA, and uses a 40-bit key, which is suitable for the encryption of commercial information. [0004] However, when the client is a mobile device such as a mobi...
