Amid the rapid development of the Internet of Things and its impact on various areas of life, ensuring compatibility between different system components is becoming an urgent task. This is especially important in the context of developing and integrating Internet of Things systems with a high level of diversity and dynamism. In this article, we consider the problem of interoperability of Internet of Things components, focusing on application layer protocols that are key to ensuring intercomponent interaction. The main purpose of the article is to develop and validate a model that will optimize the processes of interaction between system components, taking into account the specifics of protocols. The model is based on the use of temporal action logic, which provides formal verification of interactions between components and allows identifying potential compatibility problems at the early stages of development. The developed model has been tested using a software simulator that allows simulating various scenarios of interaction in the Internet of Things network. The experimental results demonstrate the effectiveness of the proposed methodology in increasing the level of interoperability between system components, which in turn reduces the risks of data loss and ensures the stability of Internet of Things systems. Due to the in-depth analysis and development of specialized methods and tools, this study makes a significant contribution to the development of theoretical and practical aspects of interoperability. However, to further improve the accuracy and versatility of the model, additional empirical studies with a larger data set are recommended.

“…The use of cryptographic accelerators increases the speed of encryption by the AES algorithm compared to its software implementation in 8/16-bit microcontrollers by 10-20 times, and in 32-bit microcontrollersup to 150 times. At the same time, the speed of hash algorithms SHA-256 with hardware implementation in 32-bit microcontrollers increases 100 times, and for hash algorithms НМАСup to 500 times [11].…”

The paper objective is to determine the basic schemes and their characteristics for ensuring the security of Internet of Things nodes using symmetric authentication cryptographic microcircuits. The main results that had been obtained by using method of structural and functional design represent potentially possible options for using symmetric authentication cryptomicrocircuits to ensure the protection of Internet of Things nodes. The analysis of the presented schemes’ functioning made it possible to form the following conclusions. The host-side private key storage authentication scheme provides a fast symmetric authentication process, but requires secure storage of the private key on the host side. The simplest authentication scheme without storing a secret key on the host side, which does not imply the use of a cryptographic chip on the host side, provides a fast symmetric authentication process, but has a relatively low cryptographic strength, since the interaction in the system is performed without a random component in cryptographic transformations, which assumes constant the nature of requests in the system, and, consequently, the possibility of cryptanalysis of messages. To increase the cryptographic strength of such a scheme, it is advisable to introduce into the interaction system a random component in cryptographic transformations and use additional hashing procedures with an intermediate key, which leads to the complication of the scheme due to double hashing, but significantly increases the level of information security of IoT nodes. Downloading software in the system is implemented using secret encryption and authentication keys, which are permanently stored in the secure non-volatile memory of cryptographic chips of IoT nodes. In this case, session keys for encrypting the firmware code or decrypting it are generated on the client and host side, respectively. This approach allows creating unique downloads of the original firmware code (application) by preventing cryptanalysts from obtaining its images and algorithms. The peculiarity of the scheme of exchange of symmetric session encryption keys of messages are: use of a secret key stored on the side of the host and the client; the determination of the session key is performed as a result of hashing a random number with a secret key, that is, the exchange of the session key is performed in an encrypted secure form.
