In the context of the development of quantum computing, traditional cryptographic algorithms used to protect data in industrial controllers are losing their stability. This article is devoted to the analysis of theoretical and applied aspects of the implementation of post-quantum cryptography in industrial automation systems. The existing threats, the architecture of industrial controllers, limitations on computing resources and requirements for cryptographic primitives are considered. An overview of the main classes of post-quantum algorithms, such as lattice, code and hash-based schemes, is provided, and a formalized analysis of security and threat models is carried out. Recommendations for the use of post-quantum solutions are presented, taking into account the features of embedded systems and industrial security standards.
