Abstract [eng] |
There are many embedded systems integrated everywhere around us: in mobile phones, TV’s, cars, household appliances, etc. Because of high degree of utilization, there is security problem – not all embedded systems has installed security solutions and in some systems these solutions may be critically important. When installing real-time embedded systems security solutions the problem is that resources in this type of systems are very limited and if resources are expanded, overall system price would grow up significantly. This paper researches real-time embedded systems security flaws, threats, identifies possible security solutions and desired solution – system encryption is realized in selected platform. When performing speed test experiments high processor utilisation and input/output speed decrease is observed. Overall system lifetime is shorter when processor works in higher utilisation if power source is battery. When installing proposed security solution in real system, experiment results need to be taken into account. |
