Secure Software for the Internet of Things

Allegro Software Expands the Allegro Cryptography Engine™ (ACE) With Support For An Advanced Data-At-Rest Solution Specifically Engineered
for the Internet of Things

FIPS 140-2 Validated Cryptography tightly integrated with a secure data-at-rest solution for Internet of Things devices

 

BOXBOROUGH, MA and SAN FRANCISCO, CA. April 20, 2015 – At the RSA® Conference 2015 in San Francisco, CA, Allegro Software, a leading supplier of Internet component software for the Internet of Things (IoT), today announced the addition of an advanced solution for securing data-at-rest using the FIPS 140-2 validated Allegro Cryptography Engine (ACE) in IoT applications. IoT devices populate the outer edge of the Internet and are often the starting point for information and trends derived from Big Data applications. When IoT devices store persistent data either locally or in the cloud, there is a risk of unintended exposure of sensitive material. Data encryption of stored data in these situations limits the risk of exposure. Allegro’s latest addition to ACE provides IoT developers with the advanced ability to easily store and retrieve data-at-rest securely from local or cloud locations. Allegro’s ACE along with the full Allegro AE™ product suite are ideally suited for creating secure IoT devices for transportation, military, energy, healthcare, and communications environments.

 

SECURING DATA AT REST IN THE INTERNET OF THINGS
Securing the Internet of Things represents many new challenges in terms of type, scale and complexity of technologies that are required. IoT devices at the edge of a network have the ability to generate large volumes of information and are often charged with securely acquiring, storing and eventually communicating data to enterprise applications. Before offloading data to cloud based applications, any sensitive information stored by IoT devices faces numerous threats and risks of unintentional exposure. Adding data encryption to the transmission process has been the traditional method for reducing this risk. However, simply encrypting data transmissions doesn’t fully address many of the threats aimed at recovering small segments of data or potentially the entire collection.

 

Allegro’s latest addition to Allegro AE and the Allegro Cryptography Engine (ACE) product suite provides IoT design engineers the ability to proactively address the threat surface created when storing sensitive data on persistent media. Rather than encrypting data at a volume or drive level where exposing a single set of keys potentially compromises a significant amount of sensitive data, Allegro’s secure data-at-rest solution encrypts information at the file level.

 

Specifically engineered for resource sensitive embedded IoT environments, Allegro’s secure data-at-rest solution uses both data encryption and authentication to detect file system validity (unauthorized modification or addition of files), limit data loss if the contents and keys of a single file are exposed, obfuscate file names and render the contents of any file useless without the application’s knowledge to prevent malicious agents from copying useful data to an external storage device. The additional capabilities of the ACE library provide integrated secure file storage and retrieval using HTTP over TLS. The library also includes application programming interfaces for independent secure file storage and retrieval. The new data-at-rest feature (like the rest of the ACE library) includes configuration parameters for tuning performance.

 

“IoT devices generate and often store data at a scale never seen before. With hundreds of millions of IoT devices deployed today and projections of billions of devices in the near future, the total potential threat for exposing sensitive data is staggering,” says Bob Van Andel, President of Allegro. “Finding ways to reduce and control this risk is vital to the continued success of IoT environments. The latest addition to the Allegro AE product suite and ACE for securely protecting data-at-rest gives development teams a greater ability to proactively control risk for their end users with FIPS 140-2 validated cryptography.”

 

The Allegro Cryptography Engine (ACE) is specifically engineered to meet the critical needs of embedded IoT computing environments and is one of the smallest, fastest, and most comprehensive FIPS 140-2 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 full Allegro AE family of toolkits is provided as ANSI-C source code. For more information, stop by Booth #2238 South Hall at the RSA Conference or visit our website: https://www.allegrosoft.com/allegro-ae.

Embedded FIPS 140-2 Cryptography

FIPS 140-2 Level 2 Logo

The Allegro Cryptography Engine (ACE) is a platform independent, high performance, resource sensitive, embedded  FIPS 140-2 Validated cryptography engine specifically engineered for the rigors of embedded computing. ACE enables OEM manufacturers to add sophisticated FIPS approved encryption technology to their designs and dramatically speed the development cycle. The ACE cryptography library is designed to meet the requirements needed for FIPS 140-2 validation.

ACE

Embedded systems are appearing in virtually all industries with the capability to communicate independently. The rapid adoption and deployment of modern communication technologies have enabled new applications in healthcare, military applications, energy management, consumer devices and many other areas. With these capabilities, comes the need for embedded device security. Any network-enabled device must be considered as a potential target for malicious intent. Encryption of sensitive data while in motion or at rest is a key component to thwarting malicious attacks and reducing risk.

ACE is a cryptographic library module for embedded computing systems that provides validated software implementations of FIPS-approved algorithms for the calculation of message digests, digital signature creation and verification, bulk encryption and decryption, key generation and key exchange. Used stand-alone or pre-integrated with Allegro's Secure IoT Suite, ACE provides CAVP validated implementations of sophisticated FIPS approved encryption algorithms for use in embedded systems. In 2005, the National Security Agency (NSA) defined a set of cryptographic algorithms that when used together, are the preferred method for assuring the security and integrity of information passed over public networks such as the Internet. Today, Suite B is globally recognized as an advanced standard for cryptography that defines algorithms and strengths for encryption, hashing, calculating digital signatures and key exchange. ACE includes a platform independent, CAVP validated implementation of the NSA Suite B defined suite of cryptographic algorithms. ACE is delivered as ANSI C source.

Securing Data In Motion

Many IoT applications often collect and correlate valuable sensitive information at the edge of the Internet and routinely transmit it to servers in the cloud securely. TLS and DTLS are the “defacto” standards for keeping data secure when communicating with servers in the cloud. Allegro’s RomSTL, embedded TLS, and DTLS toolkit, tightly integrates FIPS validated cryptography with a standards-based, embedded implementation of TLS/DTLS to keep your data secure while in motion. RomTLS is additionally integrated to make use of ACE’s support of Suite B algorithms (RFC 6460).

Securing Data At Rest

Allegro’s secure data-at-rest solution is tightly integrated with ACE validated FIPS 140-2 cryptography. Before offloading data to cloud-based applications, any sensitive information stored by IoT devices faces numerous threats and risks of unintentional exposure. Adding data encryption to the transmission process has been the traditional method for reducing this risk. However, simply encrypting data transmissions doesn’t fully address many of the threats aimed at recovering small segments of data or potentially the entire collection. Allegro's Secure IoT Suite provides IoT design engineers the ability to proactively address the threat surface created when storing sensitive data on persistent media. Rather than encrypting data at a volume or drive level where exposing a single set of keys potentially compromises a significant amount of sensitive data, Allegro’s secure data-at-rest solution encrypts information at the file level.

ACE can be used stand-alone or pre-integrated with Allegro’s Secure IoT Suite.
