Drop-in security for the smart grid comes in a module

February 20, 2014 // By Graham Prophet
ST’s KERKEY secure solution for smart-grid applications provides protection against malicious attack: developed from ST’s smart-card product lines, this ready-to-use solution includes personalisation to use the Java Card operating system, giving flexibility to program application features and implement cryptography functions efficiently.

KERKEY is an advanced security module that prevents malicious attacks on smart-grid gateways, concentrators, and smart meters. While meeting very high industry-security standards, KERKEY can be personalised to meet individual requirements.

Using the robust architecture of ST’s secure-processor family, KERKEY delivers the benefits of an established hardware foundation that satisfies CC EAL6+ Penetration Testing for smart-card ICs and FIPS-140 Penetration Testing for Multiple-Chip Cryptographic Modules.


Certified to Common Criteria (CC) EAL4+ and AVA-VAN level 5, as well as fulfilling the BSI Protection Profile for smart-grid security modules, KERKEY is the first device of its type to support the Java Card operating system (JC2.2). This allows efficient implementation of cryptographic services using a Java applet, and increases flexibility to differentiate features at the application level. KERKEY is delivered as a ready-to-use security module that requires only a small amount of final configuration.

The KERKEY secure element comes in a QFN32 package with ISO-7816 and I 2C interfaces.
