Meet or exceed FIPS 140-1 Level 2

Subscriber key pairs must be generated in a manner that ensures that the private key is not known by anybody other than the Subscriber or a Subscribers authorized representative. Subscriber key pairs must be generated in a medium that prevents exportation or duplication and that meets or exceed FIPS 140-1 Level 2 certification standard.

www.globalsign.com

EV Guidelines state: Code signing keys are to be protected by a FIPS 140-2 level 2 (or equivalent) crypto module. Techniques that may be used to satisfy this requirement include: (A) Use of an HSM, verified by means of a manufacturers certificate; (B) A hardware crypto module provided by the CA; (C) Contractual terms in the subscriber agreement requiring the

Subscriber to protect the private key to a standard equivalent to FIPS 140-2 and with compliance being confirmed by means of an audit.

already changing the requirements on a country by country basis.
