Modern smartphones have strict security requirements. And many devices already have hardware encryption to protect sensitive information. Today, Samsung introduced a new development: the S3K250AF chip and optimized software that ensures the security of personal data in isolated storage.
The South Korean electronics giant has introduced a Secure Element turnkey solution for mobile devices that is certified to the Common Criteria Evaluation Assurance Level 5+standard. Secure Element (SE) uses a combination of the S3K250AF security chip and optimized software to protect important data in isolated storage.
The chip securely stores information such as PIN codes, passwords, fingerprints, face scans, credentials, and more. This information is written directly to the SE memory, and even the smartphone OS does not have access to it. Therefore, if the "operating system" of the device is infected with some malicious application, the fraudsters will not have access to personal data. The chip communicates with payment terminals directly and also offers protection against laser attacks, power failures, and reverse engineering. In addition, Secure Element allows you to manage failed attempts and prevent repeated attacks by accepting only the last authentication request as valid.
"Effective security measures have become a key feature of modern smart devices, as they store keys to users' personal data related to services such as cloud storage and financial instruments," said Dongho Shin, senior vice president of System LSI marketing at Samsung Electronics.
Samsung said that the chip is in mass production and is already used in the Galaxy S20 line. In addition, other manufacturers can also use Secure Element in their products.
