Allegro Software Expands IoT Edge Framework with Support for TLS 1.3

Securing IoT edge devices with the latest advanced data-in-motion encryption standard for TLS

BOXBOROUGH, MA and SAN FRANCISCO, CA February 24, 2020 – At the RSA® Conference 2020 in San Francisco, California, Allegro Software, a leading supplier of security and connectivity software for the Internet of Things (IoT), today announced an advanced solution for securing data-in-motion with Transport Layer Security (TLS) version 1.3 in their RomSTL™ (TLS Client and Server) software toolkit. TLS is considered the standard for encrypting data-in-motion and the latest version, TLS v1.3, provides improved privacy, performance, and end-to-end data security. As a result, global enterprises are rapidly adopting the standard. With the majority of cloud service providers having deployed TLS v1.3, the time is ideal for IoT devices to add improved security and do the same. Allegro’s RomSTL™ fully supports TLS v1.3 and is ideally suited for use in edge devices deployed in transportation, military, energy, healthcare and other critical infrastructure environments where securing data-in-motion is a requirement.


Billions of IoT edge devices are finding their way into Department of Homeland Security (DHS) designated critical infrastructure ecosystems. The rich data streams from these edge devices drive next generation digital business systems, operational ecosystems, and valuable business outcomes. Data integrity is critical to harness the full benefits of these business outcomes. TLS provides a critical component for maintaining privacy and data integrity between deployed IoT edge devices and their cloud-based ecosystems.

Engineered for resource constraint IoT devices, Allegro’s RomSTL™ delivers the latest in standards-based data-in-motion encryption with support for TLS v1.3. The latest standard increases performance with improved handshaking protocols cutting encryption latency in half. The standard also improves security by simplifying the protocol and removing obsolete and insecure features of TLS 1.2 including SHA-1, RC4, DES, 3DES, AES-CBC, MD5, arbitrary Diffie-Hellman groups (CVE-2016-0701), and EXPORT strength ciphers. A member of the Allegro EdgeAgent Suite, a robust collection of security and connectivity components, RomSTL™ is highly configurable to meet the exacting needs of your IoT edge device.



In addition to supporting TLS 1.3, Allegro’s RomSTL™ leverages FIPS validated cryptography from the Allegro Cryptography Engine (ACE™) for all data encryption. ACE™ is specifically designed to meet the critical needs of embedded IoT computing environments and is one of the smallest, fastest, and most comprehensive FIPS validated modules on the market. ACE™ enables IoT device developers to perform bulk encryption and decryption, message digests, digital signature creation and validation, and key generation and exchange. ACE™ includes a platform-independent implementation of the NSA-defined Suite B suite of cryptographic algorithms, as well as other FIPS-approved algorithms.

“The scale of data being generated by IoT devices is unlike anything seen before. Ensuring data privacy and integrity from the IoT edge are critical when decisions and actions are taken based on business analytics derived from the collected data,” says Bob Van Andel, President of Allegro. “The utilization of the latest TLS 1.3 standard combined with Allegro’s FIPS validated cryptography help our customers take a proactive approach to managing data security risk in their IoT ecosystems.”

The full Allegro EdgeAgent Suite is provided as ANSI-C source code and is available today. For more information, stop by the Allegro Software Booth #4610 or visit the Allegro Software website:
