Embedded electronic authentication ensures that sub-systems, accessories and attachments, used with or within a piece of equipment are not counterfeit. By employing electronic authentication a manufacturer can more fully control the usage and performance of their products. Depending on the application, electronic authentication helps to maintain product reliability, accuracy, safety, and security and can also protect profit margins.

In the past systems manufacturers have employed physical authentication: expensive molded plugs or connectors, or unique form factors that would only accept the manufacturer's genuine components. These physical techniques are expensive and inconvenient for the manufacturer, and forgers are able to defeat this form of authentication. System designers are moving to electronic authentication because it allows the use of standard interfaces so products have a lower manufacturing cost, and because electronic authentication systems can be economically impractical to defeat.

The following pages provide more information on employing electronic authentication in various applications:

Authentication Backgrounder

Learn about Authentication: Why is it needed, how is it implemented, what types of cyryptographic algorithms are used and how do they differ?

Authentication IC Technology

Compare the FIPS-based cryptographic algorithms, their benefits and tradeoffs.

Cable Authentication

Electronic authentication allows cables to be authenticated prior to being enabled for operation by the system.

Battery Authentication

Electronic solutions to battery authentication offer higher level safeguards to ensure a replacement battery is from a known source.

Medical Authentication

Medical products must be protected against counterfeiting throughout the whole supply chain and traceability is a key requirement in this area; Authentication ICs provide this protection.

Industrial Authentication

Supervisory control and data acquisition (SCADA) systems are presently the target of cyber attacks. Authentication ICs provide needed protection to ensure these systems remain secure.
