The medical unit, including the physiological parameters recording unit and the treatment unit, the program control unit and the communication unit, enclosed in one portable case powered by an autonomous source, were fixed on the patient’s clothes. The unit for recording physiological parameters (EMG recording of the muscles of the legs, ECG, recording of BH), and the treatment unit were connected to the patient using 4 pairs of electrodes mounted on the body in the chest area and on the hips. As a network computer, the ASUS A-1300 laptop was used with an automatic medical data processing program connected to the communication unit via the Internet using the basic TCP / IP protocol of MTU-Inform Internet service provider. Using the communication unit, the medical unit was connected to the Internet via the GPRS protocol of the VimpelCom mobile operator. According to the plan of the experiment, after the start of the workout on the bicycle ergometer and before its completion, constant medical control was carried out - registration of EMG, ECG and BH. A network computer 20 km away from the training venue constantly analyzed the recorded medical information and transmitted codes 1 and 3 of individual programs

electropulse massage of the thigh muscles to relieve tension and improve performance. There were no indications for other types of medical care according to medical control. During the training, an attempt was made to gain access to confidential medical information of N. examined by an unauthorized Internet user by connecting to a communication session and intercepting the stream of transmitted data, however, due to the device transmitting data in the form of a packet of encrypted binary code, the information recorded by the “attacker was not has been decrypted. During the training, a violation of the communication channel was recorded as a result of a short-term attack of the MTU-Inform Internet service provider server by an unknown virus, but due to the transfer to the network of only codes of individual programs for electropulse massage of the thigh muscles, once entered into the permanent storage device, the device did not fail bsho. In addition, during the training, two failures were registered in the communication channel with a total duration of 8 minutes, which led to the operation of the automatic remote access disconnection unit in the communication unit and to the connection of the program control unit with the treatment unit for the period of absence of the communication channel. At the end of the training, patient N. turned off the device and replaced one permanent storage device with treatment programs with another, with an individual program for electropulse massage of the thigh muscles to relax them, after which the device was turned on again and its work was continued until the medical personnel of the experiment controlled duty.
