Lightweight cryptographic algorithm based on trigonometry, dedicated on encryption of short messages

The IoT technology is currently used in many areas and marked by growing popularity. On the one hand, the IoT makes our lives easier, on the other hand, it presents challenges in terms of security and privacy protection. An IoT infrastructure is characterized by a high level of threats due to, inter alia, numerous technical barriers that make it difficult to use conventional methods to protect information. The aim of this paper is to present a symmetric coding algorithm based on algebraic groups generated by specific trigonometric curves. The algorithm is dedicated to short data sequences transmitted by devices with limited computing power
