SIMPLIFIED CRYPTOGRAPHY FOR SECURE VIBRATION PARAMETERS IN POST-PROCESSING OF 3D-PRINTED PARTS

Abstract

In modern manufacturing, 3D printing technologies are gaining increasing popularity due to their ability to rapidly create complex and customized parts. However, to achieve high quality and meet industrial standards, 3D-printed parts require post-processing. Vibration containers are widely used for grinding, polishing, and other processing methods, improving the appearance and mechanical properties of products. This highlights the need to protect data generated during the vibration process, which is transmitted to central servers for analysis and management.The aim of this study is to develop a framework for a secure post-processing system for 3D-printed parts, which includes an encryption module based on lightweight ciphers to protect vibration parameters and other operational data.Methodology. This article proposes the use of lightweight cryptography to ensure the security of vibration parameters in the post-processing of parts printed using 3D printing methods. Lightweight cryptography allows for efficient data encryption with minimal resource consumption, which is critical for systems with limited computational capabilities. The paper discusses various post-processing methods – such as mechanical grinding and polishing – and their impact on the surface quality and compliance with standards. The cryptographic protocols used to protect data during its transmission from vibration containers to central servers are described in detail.The results can contribute to the advancement of 3D printing technologies and the creation of new post-processing methods that meet contemporary requirements for quality and information security.Scientific novelty. The use of the SPECK cipher has proven to be the optimal solution for resource-constrained systems, as it provides high encryption speed with low energy consumption, which is critical for microcontrollers and embedded systems used in post-processing operations.Conclusion. The proposed solutions provide reliable protection against unauthorized access and manipulation, improving overall manufacturing security and efficiency. Special attention is given to the integration of cryptographic methods into monitoring and control systems for vibration processes, ensuring high accuracy and reliability in data processing.
