RomPager AE is a full-featured HTTP 1.0/1.1 Web server toolkit that offers IPv4 and IPv6 operation, CGI-style user exit support, an internal security database, optional file support, and the PageBuilder HTML offline compiler.  The PageBuilder compiler dramatically reduces development time, coding effort, and potential errors by converting HTML into compilable source code.  The compiler provides full support for HTML (2.0, 3.2, 4.0 and 5.0), XHTML, JavaScript, object compression, application compression, and international languages with dynamic phrase dictionaries.

RomXML AE

Never worry about formatting or mapping data types across hardware architectures again. RomXML AE provides a processor-independent way of encoding data for interchange between diverse systems. Parse and frame XML data with an efficient and effective solution designed for use with embedded systems.

RomXOAP AE

Offers design engineers a comprehensive solution for building connectivity between embedded designs and enterprise IT environments utilizing standards-based SOAP technology. Embedded devices enabled with SOAP technology are essential for enterprise IT in remote data collection, operations, industrial automation, sensor networks and monitoring applications. Designed for use in demanding embedded environments, RomXOAP provides a lightweight SOAP technology without carrying the overhead of general purpose solutions.

RomCLI AE

Looking to implement a Cisco IOS-style Command Line Interface? RomCLI is your solution. Define command trees, help, actions routines, security realms and more using XML and the included CliBuilder pre-compiler will create all the internal parsing tables and execution harness for the CLI Parser system. Access device variables using an API that can share existing SNMP style SET and GET routines. Leverage the capabilities of RomCLI and the included tools to decrease your time to market with a feature-rich command line interface.

RomSTL

RomSTL is a small, resource sensitive TLS client and server solution specifically engineered for embedded systems. RomSTL is pre-integrated with the Secure IoT Suite making it easy to envoke TLS as needed. RomSTL supports the latest RFC standards for TLS 1.0, TLS 1.1, and TLS 1.2 secure server and client sessions. The toolkit is hardware and software platform agnostic and written from the ground up for efficiency. The encryption protocols interoperate with any secure browser or server and include RSA, RC4, DES, 3DES, SHA, AES, and Suite B algorithms.

RomCert

RomCert is a platform-independent implementation of the Online Certificate Status Protocol (OCSP) and the Simple Certificate Enrollment Protocol (SCEP) and makes embedding security certificate management into resource sensitive embedded systems and consumer electronics fast, easy, and reliable while decreasing time to market.

RomSShell AE

RomSShell AE is an embedded Secure Shell version 2 (SSH) toolkit. SSH provides encrypted communications between hosts over an insecure network. RomSShell AE offers a range of client authentication options in addition to X.509 public-key certificates. RomSShell AE can also be used for port forwarding (sometimes called SSH tunneling), allowing you to arbitrarily tunnel secure TCP connections. RomSShell AE also supports the latest RFCs for implementing Suite B with Secure Shell.

Allegro Cryptography Engine (ACE)

The Allegro Cryptography Engine (ACE) is a cryptographic library module specifically engineered to meet the requirements needed for FIPS 140-2 level 2 validation. The module provides developers with a common software API to enable bulk encryption and decryption, message digests, digital signature creation and validation, and key generation and exchange. Suite B is an advanced standard for cryptography that defines algorithms and strengths for encryption, hashing, calculating digital signatures, and key exchange. ACE includes a platform independent, government validated implementation of the NSA Suite B defined suite of cryptographic algorithms.

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.
