Most of us assume that security comes from the operating system or application software. However, firmware is also at risk, including anything that barely hovers over the physical layer (silicon) in the chip. Embedded security is especially important in blocking seemingly innocuous pathways for hacking, such as in an automotive infotainment center.

Most of us assume that security comes from the operating system or application software. However, the firmware is also at risk, including anything that barely hovers over the physical layer (silicon) in the chip. Booting up a chip means that some hardcoding in the silicon itself is permanent (unless a portion of the chip is FPGA-based). Anything above that permanent coding, which acts like a tiny boot loader, is vulnerable to hacking.

After a chip is powered up....Read the full story HERE.

Most of us assume that security comes from the operating system or application software [....] it’s imperative that security starts at the physical layer as a function provided by the chip manufacturer.
