2024: Russia approves first GOST for cryptographic data exchange protocol in industrial systems
The Federal Agency for Technical Regulation and Metrology (Rosstandart) by order of February 15, 2024 No. 235-st approved the specification of the secure exchange protocol for industrial systems GOST R 71252-2024 "Information Technology. Cryptographic information protection. Secure Exchange Protocol for Industrial Systems. " This was reported to TAdviser on February 22, 2024 by representatives of the InfoTeCS Group of Companies. The standard comes into force on April 1, 2024 instead of the recommendations for standardization R 1323565.1.029-2019.
This document became the first national standard of the Russian Federation to describe a cryptographic protocol, the company said. The development of the national standard was carried out by InfoTeCS specialists. The document was submitted by the Technical Committee for Standardization TK 26 "Cryptographic Information Protection."
In general, CRISP (CRyptographic Industrial Security Protocol) is a non-interactive secure data transfer protocol developed for use in industrial systems. The development of this protocol was carried out specifically for industrial systems in order to ensure the transmission of compact blocks of industrial data and to abandon the sufficiently high requirements for computing power and communication channels that are imposed when using protocols based on CMS messages (Cryptograghic Message Syntax).
CRISP implements the protection of original messages by optionally encrypting them, as well as calculating the imitation rate, in particular for message authentication and for protecting against the imposition of repeated messages using cryptographic methods.
 | CRISP is a collection of a set of fields, rules for their formation and processing, and can be used with any data transmission protocol capable of delivering the generated data to the destinations. It does not require establishing connections, has minimal overhead and high energy efficiency, - emphasized in InfoTeCS. - Cryptographic sets used in the protocol based on the Magma block cipher ensure efficient operation, including on low-power devices. |  |
The CRISP protocol properties allow with its help, protect data transmitted both in - TCP\IP nets and in networks built not on the basis of the protocol stack/, TCPIP for example, when using narrowband LPWAN transmission technologies. The new national standard can be used as a layer of protection for the LoRaWAN RU protocol (GOST R 71168-2023), NB-IoT ZigBee, XNB, as well as for a number of industrial protocols. High energy efficiency allows the use of a cryptographic protocol not only in automated process control systems (), APCS but also in IIoT systems where devices are traditionally powered by a battery or receive it from the operating environment.
2019: Secure exchange protocol approved for CRISP industrial systems as guidelines
By the decision of Protocol No. 23.1 of the Technical Committee for Standardization "Cryptographic Protection of Information" (TK26) dated May 27-30, 2019, methodological recommendations MR 26.4.001-2019 "Secure Exchange Protocol for Industrial Systems (CRISP 1.0)" were approved. This was announced on June 27, 2019 by Infotecs.
The protocol described in the document is designed to protect communications between ACS, M2M- and IIoT devices.
CRISP is a Russian cryptographic protocol that provides a mode for ensuring the integrity and authenticity of transmitted information without ensuring confidentiality. For most ACS, there is no need to hide information due to its rapid obsolescence, for industrial protocols it is more important to protect information from unauthorized changes. If necessary, the protocol provides an optional encryption mode to ensure confidentiality. A distinctive feature of CRISP is the small amount of data added and the absence of the need to establish a session. This feature allows you to use the protocol to protect information when transmitting over communication channels with a narrow bandwidth. When CRISP is used in industrial real-time protocols and Internet of Things protocols, processing delays are minimal due to the use of symmetrical mechanisms and predefined crypto sets. In MR 26.4.001-2019 "Secure Exchange Protocol for Industrial Systems (CRISP 1.0)" as of June 2019, two cryptographic sets based on the MAGMA block cipher in the simulation production modes and in the gamma mode according to GOST 34.13-2015 are defined.
InfoTeCS specialists took an active part in the development of the protocol within the framework of the working group "Cryptographic mechanisms for M2M and industrial systems TK26" and became the authors of the document.
