Problems solved by technology

[0003] Based on this, this application provides a method for generating a key index and a method for sending data, which are used to use the library-level index to identify the key library on the server side, and then use the obfuscated random number and the library-level index to form a key The key index method can not only solve the problem of incompatibility between the new and old versions of the key store on the server side, but also make it difficult for the attacker to obtain the index in the key index by confusing the random number, thereby increasing the Security of data transmission between server and terminal

Embodiment Construction

[0122] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0123] The inventor of the present application found during the research process that in the prior art, when the server sends the encrypted data, it also needs to send the key index corresponding to the encryption key used to encrypt the data to the terminal. And if the server directly sends the key index and encrypted data to the terminal, once the attacker obtains the key index, he can parse out the encryption key and obtain the unencrypted original data, so the security of data t...

Abstract

The invention provides a data transmission method and device and a key index generation method and device. The data transmission method comprises steps: connection with a terminal is built in responseto a server, and a session key negotiated during a connection building process is acquired; and an encryption key and a key index of the session key are determined, wherein the key index is used foruniquely identifying the session key, and the key index comprises a library grade index and a random number after confusion, and the session key encrypted by using the encryption key and the key indexare together sent to the terminal. By adopting the embodiment of the invention, the problem of incompatibility between a new version and an old version of a key library for the key index in the priorart can be solved, and the data transmission security is enhanced.

Description

technical field [0001] The present application relates to the technical field of Internet data processing, in particular to a data sending method and data sending device, and a method and device for generating a key index of an encryption key. Background technique [0002] At present, with the popularization of Internet technologies, more and more users use terminals, such as computers or mobile terminals, to perform data interaction with various platforms through the Internet. For example, log in to the mailbox to send and receive emails, or publish posts, or conduct online shopping, and so on. Each interaction needs to establish a connection between the terminal and each platform server for data interaction. In some scenarios, after the server successfully establishes a connection with the terminal, it can send an encrypted data to the terminal. When the terminal interacts with the server later, the encrypted data will be sent directly to the server for verification, so t...
