STMicroelectronics Secure Authentication Solution

Authentication products are secure elements used to authenticate devices for brand protection, secure connections to the cloud and remote servers, and ensure platform integrity.

With superior ability to store and handle secrets, authentication products contribute to safeguarding a company’s image, reputation, and revenues against cloning and theft and ensure secure and trusted services.

Running on a CC EAL5+ platform, STSAFE-A is a highly secure authentication solution with security features certified by independent third parties. Its command set is tailored to ensure strong device authentication, monitor device usage, assist a nearby host secure channel establishment (TLS), and safeguard host platform integrity.

In this STM Secure Authentication Solution, the STSAFE-A110 secure element provides a unique identification with an X.509 certificate that ensures strict device authentication to prevent the counterfeiting of genuine peripherals and IoT devices.

As a companion chip to STM32 microcontrollers, the STSAFE-A110 is easily integrated into existing solutions, mainly thanks to the comprehensive STM32 development ecosystem.

ST recommends using an STM32L476RG, an ultra-low-power microcontroller based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU) format, which supports all Arm® single-precision data-processing instructions and data types. It also implements a full set of digital signal processor (DSP) instructions and a memory protection unit (MPU), enhancing application security.
