New STSAFE-A1SX optimized and certified (CC
EAL5+) secure element provides activation and secure connection to
the Sigfox LPWAN IoT network
GENEVA, February 23, 2017 -- STMicroelectronics
(NYSE: STM), a global semiconductor leader serving customers
across the spectrum of electronics applications, announced the
expansion of its STSAFE family of secure elements with the
introduction of a powerful plug-and-play solution that provides
state-of-the-art security features to devices connected to the
Sigfox low-power wide-area network (LPWAN).
The new STSAFE-A1SX secure element (SE) is based on a
tamper-resistant Common Criteria EAL5+ -certified SE technology
that enhances the integrity and confidentiality of transmissions to
and from the IoT device over the Sigfox network. The secure element
runs an optimized secure application that combines ST's proven
expertise in electronic security for applications in banking,
e-commerce, and identity with Sigfox's expertise in networking and
data communications for the emerging IoT world.
STSAFE-A1SX is a tiny and cost-effective secure IC solution that
connects to the microcontroller of the IoT application or module
via an Intelligent Interface Controller (I2C) connection. The chips
are provisioned in ST's secure-personalization center with device
ID and keys that allow plug-and-play secure connection to the
Sigfox cloud, and further ensure data-exchange integrity and
confidentiality. Whether the frame is an uplink or downlink
message, the STSAFE-A1SX secure element generates or verifies
payload proof of integrity as well as optional encryption or
decryption. Keys and other secrets are always protected inside the
secure element during manufacturing and over the end device's full
life.
"By executing Sigfox security services within our certified
tamper-proof STSAFE-A1SX, we support Sigfox Ready(TM) device makers
and Sigfox application providers to implement state-of-the-art
end-to-end security," said Laurent Degauque, Secure Microcontroller
Marketing Director, Microcontroller and Digital ICs Group,
STMicroelectronics. "The STSAFE-A1SX makes security over the Sigfox
network even stronger and more straightforward. Our customers
simply attach this secure element to their general-purpose MCU,
such as an STM32, and focus on application development."
"It's more important than ever to consider and plan the security
architecture at the very beginning of the design and development of
an IoT solution," said Laetitia Jay, CMO at Sigfox. "Working
closely with STMicroelectronics has been fundamental to offering
state-of-the-art certified tamper-resistant security to our
ecosystem of partners and customers. The integration of the ST
secure element with the Sigfox libraries, the STM32, and the
S2-LP sub-1GHz transceiver, provides an ultra-low power, high
performance turn-key solution that brings end-to-end security in
IoT and Sensor-to-Cloud applications to the next level."
Like other members of the STSAFE family, the STSAFE-A1SX will
come with a full ecosystem of tools and software to speed its
adoption by developers with or without expertise in secure designs.
The device is available on expansion boards directly compliant with
the popular STM32 Open Development Environment. Associated with the
ST S2-LP sub-1GHz transceiver and the STM32, ST provides a
complete reference design of a Sigfox Ready device:
- NUCLEO-L053R8, an STM32 Nucleo-64 development board with
STM32L053R8 MCU
- STEVAL-FKI868V1 sub-1GHz development kit, equipped with a
low-power STM32L MCU to control the S2-LP sub-1GHz transceiver and
the ST-LINK/V2-1 debugger and programmer for firmware updating
- STSAFE-A1SX
The STSAFE-A1SX secure element is scheduled to enter production
in May 2017 in both 4x5mm SO8N and 2x3mm UFDFPN8. Please contact
your ST sales office for pricing options and sample requests.
