Article title Hardware and software tools application for information protection in telemedicine

Abstract (resume)

Introduction. To provide the integrity of data while it transmission in telemedicine systems, two standards with a protocol type of protection are currently used. However, more effective and more crypto-stable software and hardware implementations of AES standard are widely used in communication networks of other assignments. The within this standard possibility of using the method of dynamic generation of closed for users keys, which can be used to protect data in telemedicine networks, is considered in the paper.

Objective. AES algorithm modification to protect telemedicine data transmitted in open computer networks. Study one of the possible options for dynamic generation of the encryption key, which is closed to the end-user. Practical software and hardware implementation of the investigated algorithm.

Object and methods. Operations analysis of nonlinear permutations of square matrices elements, and construction of a set of permutations with given properties. Simulation of proposed algorithms using personal computers (C ++ Microsoft Visual Studio). Construction of a closed communication channel in an open computer network with the help of the MK20DX256VLH7-type microcontroller in conjunction with the ESP8026 Wi-Fi module.

Results. A computer model of the proposed algorithm is constructed and its possibilities for data protection in an open network have been studied. The software and hardware implementation of the data transfer algorithm in a wireless network based on microcontrollers has been created.
