This layered approach is increasingly important in light of the electronics-driven revolution now reshaping the automotive industry. eMobility, Assisted/Automated Driving and Connectivity are making automotive systems more complex and more networked than ever before. Every aspect of the increasingly connected car is a potential attack point (Figure 1), which makes security architecture a lead consideration in vehicle designs. At the same time, companies working on development of autonomous functionality tell us that getting consumers comfortable with relying on these systems is critical to their long-term success. This requires what Infineon calls “dependable systems;” vehicle owners must be confident of the system’s safe and secure operation under all conditions. As the remote hack described above makes clear, securing electronics functionality plays a big role in building consumer trust.
