Multimedia Systems as Immune System to Improve Automotive Security?
Résumé
Our motivation is driven by the fact, that security mechanisms often cause additional efforts and costs, and need to be aligned with safety goals - protecting human and environment. Especially in the field of automotive security, producers are seeking cost efficient, environmental-condition-adaptive (robust) and fast approaches, if possible combined with existing concepts reusing resources. Initially, working in automotive security, it was easy to see that a wide variety of attacks is possible, e.g. using knowledge from classical computer and network security incidents. It became clear, that malicious activities on car IT systems might also lead to safety relevant issues such as accidents with threats to life or physical condition of the driver herself, occupants and people in the environment. We are inspired by the basic law of robotics established by I. Asimov1 and apply it to automotive design: "1. A vehicle may not injure a human being, or, through inaction, allow a human being to come to harm. 2. A vehicle must obey orders given it by human beings except where such orders would conflict with the First Law. 3. A vehicle must protect its own existence as long as such protection does not conflict with the First or Second Law.". This entire bunch of requirements would cause "heavy" technology and expensive solutions. Coming from multimedia security, it became stepwise clearer that we cannot neglect known security mechanisms, but it is worth to combine them with knowledge about multimedia systems (MM systems). For example MM sensory, data streams, protocols, quality etc. enable the car to perceive the occupants and environment more precisely and can help to detect in-car and outside-car anomalies caused by security incidents with an estimation/prediction of harm. Existing automotive components designed for safety, entertainment and comfort services should be able to help in achieving secure and safe car behavior. In the article we discuss the opportunity to understand vehicles as single and cooperative MM systems with the ability to become an enabler for future automobile security detection, warning and reaction strategies - as a kind of vehicular immune system building Multimedia-enabled Asimovian Secure Automobiles (MASA).
