Samsung’s proud Galaxy line of smartphones offers a range of security features, such as the Samsung Knox, which allows data isolation, Secure Wi-Fi that can be browsed through public network security, and Find My Mobile, which can be remotely blocked if a device is stolen. Its latest Galaxy S20 lineup also comes with security chips, part of the Knox platform that shields user data from advanced hardware attacks. Today, the company details how its security element chips are hardware-protected against all kinds of attacks.
Samsung says a new security-focused chip is embedded in the device, which uses the physical shielding principle to isolate confidential data stored on the device. The chip can detect irregular voltage or temperature changes, which could be a signal from an attacker who maliciously tampered with the device’s hardware, and the processor has a secure algorithm designed to prevent side channel attacks.
At the lock screen level, the security element chip also protects the Galaxy S20. In particular, the system can ensure security by preventing an attacker from resetting an error counter, a tool that tracks unlock failures, and ensures that PIN codes, patterns, or passwords are not subject to exhausting speculation.
Last but not least, it also protects private keys or sensitive data on third-party applications.
The chip was originally incorporated into the Galaxy S20, but Samsung has also started using it on devices made by other OEMs. In addition to this component, Samsung’s encryption system has other elements to jointly build a security line.
