| Abstract [eng] |
Autonomous robots are used in a wide range of areas, ranging from households to military industry. Soon autonomous robots will inevitably become more intelligent and will be used in almost every person's home. Therefore, it is time to think about using secure communication method that would help to avoid selfish strangers and malicious attacks that could allow the leak of sensitive personal data. However, when developing a secure communication method for an autonomous robot, it is necessary to consider its limited resources - both power consumption and low power computing capabilities. Both simplified and more sophisticated communication protocols can be used to achieve this, but additional security needs to be implemented. For this reason, the aim of the final thesis is to improve the existing methods of autonomous robotic communication in the field of safety, thus offering an effective method of communication protection. The developed method must meet the requirements of the robot’s limited resources: to be safe and fast enough, but not to use too much computing resources and electricity. The literature analysis reviews and examines current robotic security issues and vulnerabilities, compares used communication methods. Secure communication in the method prototype is implemented using two types of protocols - HTTP and MQTT. The results are presented in the experimental study, which compares the security levels modifications of the protocols, use of calculation resources, speed, additional data overhead and the amount of electricity consumed. |
