Embodiment Construction

[0102] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0103] In the prior art, a typical HTTPS communication process is as follows figure 2 Shown:

[0104] Among them, Client represents the client, Server represents the server, and the communication steps between the client and the server are as follows:

[0105] 1. The client sends a handshake request;

[0106] 2. The server obtains the SSL encryption key, including public key and private key;

[0107] 3. The server returns the SSL encrypted public key;

[0108] 4. The client checks the validity of the public key, if the public key is valid, generates a random KEY, and uses the public key to encrypt the random KEY; if the public key is invalid, a warning message is displayed;

[0109] 5. The client se...

Abstract

The invention provides a data interaction method, a client and a server, so as to solve the problems of requested replaying and client computer safety that cannot be solved by adopting HTTPS (Hyper Text Transfer Protocol Secure) technique. The method comprises the following steps: obtaining a timestamp from a service terminal; sending the first identifying information of a user, the timestamp and verifying data generated according to the first identifying information of the user and the timestamp to the service terminal; obtaining certified data encrypted by the service terminal, wherein the certified data comprises the encrypted data generated for the timestamp and second identifying information of the user; and using the certified data to access the service terminal. According to the method provided by the invention, HTTPS encryption and improved MD5 are used together while the encryptions at the client and service terminal are adopted, so that the possibility of distorting and falsifying data at 'end' and 'path' is efficiently avoided. Besides, the timeliness control is performed on interface calling by using effective time through the timestamp, so that the data damage risk caused by recording and largely replaying a user request is efficiently avoided.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a data interaction method based on data integrity and confidentiality, a client and a server. Background technique [0002] At present, a large number of client programs use the standard HTTP protocol to communicate with the server. [0003] HTTP is the abbreviation of HyperTextTransferProtocol (Hypertext Transfer Protocol). Its development is the result of cooperation between the World Wide Web Consortium (World Wide Web Consortium) and the Internet Working Group IETF (Internet Engineering Task Force), and they finally released a series of RFC (Request For Comments), RFC1945 defines the HTTP / 1.0 version, the most famous of which is RFC2616. RFC2616 defines a version commonly used today - HTTP1.1. The HTTP protocol is a transmission protocol used to transmit hypertext from a WWW server to a local browser, which can make the browser more efficient and red...
