This paper describes the security implications of FPGAs to the Trusted Computing Base of Embedded Systems. It gives an overview
of different FPGA architectures and discusses the security measures and shortcoming of modern FPGAs. Furthermore, it shows
how an attacker can exploit these shortcomings and integrate rootkit-like code inside the FPGA. After a discussion on possible
countermeasures, a description on the different ways a rootkit can be deployed into the FPGA is given.
