Proprietary software embedded in the hardware security chip
Separate storage of sensitive data in a digital personal safe
Achieved 'EAL 5+' rating under the Common Criteria


Recently, the importance of protecting sensitive personal information is growing due to personal authentication, financial transactions, and the use of cloud services via mobile devices.

Accordingly, on the 26th, Samsung Electronics’ System LSI business unit unveiled an integrated security solution for mobile devices consisting of a hardware security chip and software.

Unlike conventional methods where sensitive information such as passwords and fingerprints was stored in general memory like eUFS (embedded Universal Flash Storage), this solution enhances security by storing the information in a separate security chip protected by optimized software.

This solution consists of the 'S3K250AF' hardware security chip, capable of defending against various physical hacking attacks using power and lasers, and Samsung Electronics' proprietary security software that prevents hacking attempts such as resetting error counts or intercepting user information during transmission.

S3K250AF has obtained the EAL 5+ rating, the highest level among security chips for mobile devices under the Common Criteria (CC).

CC is a common evaluation standard established to mutually certify information security evaluation standards that differ by country. It is classified into grades from EAL 1 to EAL 7, and the higher the grade, the safer personal information can be stored.

Meanwhile, Samsung Electronics' new integrated security solution was installed in the recently released Samsung Galaxy S20.
