Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "front", "rear", "circumferential" and...

Abstract

The invention relates to the technical field of information security, and discloses a data encryption transmission system and a data encryption transmission method, and the method comprises the steps that a data center and a key negotiation server negotiate to obtain a first shared key; the data center is connected with message-oriented middleware and is used for encrypting plaintext data by using the first shared key to obtain a first ciphertext and publishing the first ciphertext to a subscription queue of the message-oriented middleware; the key negotiation server is connected with the data center and is used for acquiring queue information corresponding to the subscription queue and encrypting the first shared key by using the queue information to acquire a second ciphertext; and the terminal is connected with the message-oriented middleware and the key negotiation server, and is used for obtaining the queue information, the first ciphertext and the second ciphertext, decrypting the second ciphertext according to the queue information to obtain the first shared key, and decrypting the first ciphertext according to the first shared key to obtain plaintext data. The key negotiation server, instead of distributed terminals, carries out key negotiation with the data center, so that the communication overhead is saved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a data encryption transmission system and a data encryption transmission method. Background technique [0002] With the deep integration of the Internet and energy production, transmission, storage, consumption, and energy markets, the power industry has entered an era of networking, intelligence, and integration. The current power system has security and real-time problems in the transmission of different types of massive data for distributed terminals. The publish / subscribe model based on message middleware is often used to solve the data transmission problem for distributed terminals. Existing secure transmission methods based on message middleware include schemes that can satisfy dynamic queues. However, there are problems in the group password management that is applicable to the dynamic queue, the overhead of the message publishing end and the receiving end i...
