HCC Embedded has released a new Embedded Encryption Manager that allows developers to secure IoT systems using multiple encryption or hash algorithms through a uniform interface. Using a well-defined interface shortens development time as developers can now simply drop-in the Manager and encrypt data stored on flash or transmitted across a network. Such security is necessary to block potential hackers looking for a backdoor into the microcontroller-based system.

Developed using a formal process, HCC Embedded Encryption Manager undergoes verification to ensure stability and enhanced integrity. It is delivered with a full MISRA compliance report and a test suite that includes 100% MC-DC coverage. This level of verifiable quality in the area of security and encryption stands in direct contrast with the widely used ‘code-then-test’ methods, which have resulted in serious security breaches, such as Heartbleed.

Using HCC’s Advanced Embedded Framework, the Embedded Encryption Manager is completely portable and algorithms are accessed by reference through the Manager, freeing the application of direct references to a particular algorithm. The Encryption Manager can be used with HCC’s verifiable TLS or any other application requiring access to a suite of verifiable encryption algorithms.

Key Features:

All code is fully MISRA compliant
Test suite includes 100% MC/DC coverage of the module and the algorithms
Module can be extended with new algorithms
All algorithms are designed to have hardware-specific optimizations
Module includes the ability to dynamically add and verify microcontroller-specific algorithm implementations

Verified software implementations of the following algorithms: AES, 3DES, DSS, EDH, MD5, RSA, SHA1, SHA256

The software includes hooks to allow hardware-specific optimization to be implemented where supported by the target controller along with the verification suite to ensure that the hardware optimizations are done correctly.

Director of Marketing David Brook said, “Transmission and storage of embedded data should not open developers and their customers to vulnerabilities due to poor coding quality. HCC is committed to bringing state-of-the-art quality processes to the Internet of Things. Our Embedded Encryption Manager is the latest step in our project to secure all embedded devices whether they are smart meters, spa pool controllers, or medical devices.
