Currently, the study of microcontroller and microcircuits by students is becoming very important and in demand when acquiring competencies in the computer engineering educational program. This knowledge and skills will be necessary for the employment of graduates in industry, science and education. There are more and more large technical systems that require an understanding of the architecture of these systems and the skills to use these systems in a safe and reliable way. This article discusses technologies of fully homomorphic encryption that allow performing operations on encrypted data without disclosing them, so they have a huge potential for use in solving problems of storing and processing personal data. The growing interest in such technologies has led to the emergence of software tools and libraries that support fully homomorphic encryption. However, due to the relatively young age of this field of cryptography, standards and guidelines for the use of fully homomorphic encryption schemes are still in development. Thus, the use of these libraries without paying attention to the issues of cryptographic strength of the schemes used may have significant information security risks. In this work, algorithms, principles and methods for creating libraries on the Arduino platform are investigated and developed, which can be used as guidelines for the development of complexes of this kind. Arduino is increasingly being used for training in technical educational programs. As a result, every year at various conferences on engineering education and in journals, many articles are published on the integration of Arduino in teaching.
