Product overview
Description
The STSAFE-S320 system on chip is a top-class embedded secure element (eSE) able to manage Java® Card applets from different stakeholders (such as the user, original equipment manufacturer (OEM), hardware integrator, or service provider).
The device is compliant with Java® Card 3.0.5 with enhanced mechanisms of memory management, security, and data management.
It also supports the GlobalPlatform® Card Specifications v.2.3 and related amendments:
GlobalPlatform® Amendment C – Contactless Services v1.3 (support of the "Cumulative Delete" and "Get Status" sections)
GlobalPlatform® Amendment D – Secure Channel Protocol SCP03 v1.1.1
GlobalPlatform® Amendment F – Secure Channel Protocol ‘11’ v1.2.1
GlobalPlatform® Amendment H – Executable Load file Upgrade v1.1
GlobalPlatform® Access Control v1.1
GlobalPlatform® APDU communication over I²C/SPI based on the GlobalPlatform® “APDU Transport over I²C/SPI” specification v1.0
GlobalPlatform® SE Configuration v2.0
The STSAFE-S320 devices are based on Arm® cores.
The STSAFE-S320 is integrated with AndroidTM applications “Keymint” and “Weaver”. It can also host STMicroelectronics applications for secure storage.
It provides state-of-the-art security of the provided functionality, resistant to recent EMVCo/JIL Hardware-related Attacks Subgroup (JHAS)-identified vulnerabilities.
Moreover, the STSAFE-S320 ensures a high level of security and isolation between applications, and Common Criteria EAL5+ certification is ongoing.
