How important is security?

Security is a key question for the IoT. Just a few years ago, embedded computing customers were more concerned with security standards compliance, if it was required. Now, a broader understanding is evolving – security is essential to managing liabilities.


More and more security threats are appearing, and more privacy breaches are occurring. Safeguarding both intellectual property and data means all parts of a system must be protected. Security must be affordable, and manageable. End points and applications must be trusted, with industry-standard APIs allowing integration with existing IT environments.

Regarding security for the local embedded processing node at the physical layer, there are a variety of cryptographic engines and security accelerators to support data encryption (including DES, AES, and other algorithms) and authentication (such as SHA). Additional layers of security software, as well as best practices related to boot-up routines, are among the variety of security approaches available.
