Embodiment Construction

[0049] A kind of SM2\SM3\SM4 hybrid encryption method software design for remote measurement and control terminal system (RTU) figure 1 shown.

[0050] Underlying in-depth packaging technology scheme in the cryptosystem:

[0051] The encrypted data transmission adopts the underlying in-depth encapsulation technology, and the specific principles are as follows:

[0052] Provides basic server-side network communication functions. The functions mainly include opening the server, closing the server, managing the client connection list, managing the pending acceptance request list, and issuing asynchronous operations. At the same time, it provides the following basic extension interfaces to its derived classes through the polymorphic mechanism:

[0053] (1) The processing interface for establishing a new connection.

[0054] (2) The processing interface when the client disconnects.

[0055] (3) The processing interface when a connection error occurs.

[0056] (4) The processin...

Abstract

The present invention discloses an SM2 / SM3 / SM4 hybrid encryption method aiming at a remote measurement and control terminal system, belonging to the industrial control information safety correlation field. A digital signature secret key distribution scheme based on an elliptic curve is provided, the software part employs an embedded Linux safety reinforcement operation system and the SSL encryption WEB management interface to ensure the data collection and the end-to-end channel source encryption of the monitoring control system software in the purpose that the encryption rate is not lower than 20MB / s. The hybrid encryption algorithm data transmission speed is improved and reaches up to the 33MB / s. An authentication secret key distribution scheme of the difficulty digital signature based on the solution of the elliptic curve discrete logarithm problem is provided and is configured to perform authentication of the conference secret key and the issuers.

Description

technical field [0001] The invention relates to an SM2\SM3\SM4 hybrid encryption method for a remote measurement and control terminal system (RTU), which belongs to the related field of industrial control information security. Background technique [0002] In recent years, communication technology, computer technology, network technology, and control technology have made rapid progress. New technologies are widely used in various automatic control system devices. New automatic control products are constantly emerging, and mature automatic control products are constantly being upgraded. , The emergence of new technologies has driven the industrial upgrading of the industry. The remote measurement and control terminal system (RTU) is the core device that constitutes the comprehensive automation system. The early RTUs could only do simple data collection and control of some switches with weak communication capabilities, and most products used custom non-standard protocols. Af...
