Embedded Security Solutions for Automotive Applications.

In this paper we present a number of architectural security solutions based upon concrete hardware components such as customized security controllers, trusted platform modules (TPMs), "security boxes", FPGAs and ASICs. We analyze benefits and disadvantages of each solution proposed in terms of physical and cryptographic security, costs, needed and achievable performance. We also discuss the consequences of the solutions with respect to several wide-spread security applications including immobilizer systems, component identification, software flashing, etc. [ABSTRACT FROM AUTHOR]
