Cm security chrome for pc verification#
It uses an embedded 8192-bit RSA public key to verify the cryptographic signature on the read-write firmware.Īfter the read-only firmware verifies and runs the read-write firmware, the latter performs a similar verification operation on the operating system kernel before running it. When you press the power button, our read-only firmware starts a process we call Verified Boot. The custom firmware chip consists of two parts: a read-only firmware and a read-write firmware that can be updated. Our security model is rooted in two pieces of hardware that ship with every Chromebook: a custom firmware chip and a Trusted Platform Module (TPM). (We’re already handling updates and malware resistance on the Chromebook automatically!) Let’s take a quick look at some of the Chromebook security features that, when paired with good web hygiene, make it easier to browse the web safely. While no software is perfect or completely secure, we believe we’re taking an important step forward. The result is a multi-layered set of defenses which boosts the security of Chromebooks against malicious software that could compromise and linger on the system. These features demonstrate the Chrome team’s overall focus on providing usable security even as we continue our rapid development work on the project.Ĭhromebooks take Chrome and its core values (simplicity, speed and security) and apply them to our own operating system infrastructure. In the past, we’ve written a good deal about the Chrome sandbox and other security features that we built into the Chrome browser.
