Samsung updated its security solution for mobile devices by introducing the S3FV9RR, a second-generation security chip with Secure Element and enhanced security software.

In their official statement, Samsung said that the Secure Element (SE) chip and the enhanced software are the key components to S3FV9RR helping to protect data and tasks, such as booting, isolated storage, mobile payment and other applications. It is designed for mobile devices and is ready-to-use (turnkey) in gadgets such as flagship smartphones, e-passports, and hardware wallets for cryptocurrencies.

The chip works independently from a device's main processor, and it supports the hardware-based root of trust (RoT), secure boot and device authentication processes. When a device's bootloader initiates, the S3FV9RR activates a chain of trust where it sequentially validates each piece of firmware with approved keys. This secure booting process is handled by the security chip's RoT, which helps prevent unwanted or unauthorised software updates.

"In this era of mobility and contact-less interactions, we expect our connected devices, such as smartphones or tablets, to be highly secure to protect personal data and enable fintech activities such as mobile banking, stock trading and cryptocurrency transactions. With the new standalone security element solution (S3FV9RR), Samsung is mounting a powerful deadbolt on smart devices to safeguard private information," said Dongho Shin, senior vice president of System LSI marketing at Samsung Electronics.

The new chip is Common Criteria Evaluation Assurance Level (CC EAL) 6+ certified, which exceeds the security certification strength found on the first-generation S3K250AF installed on existing Galaxy S20 series smartphones. CCL EAL 6+ is the highest certification level acquired by a mobile component, according to Samsung. The S3FV9RR also has double the secure storage capacity of its predecessor.

Samsung said that the S3FV9RR is expected to available for device makers and their mobile electronics by Q3 2020.
