ia-5(2)(a)

ia-5(2)(a)[1]

validates certifications by constructing a certification path to an accepted trust anchor;

ia-5(2)(a)[2]

validates certifications by verifying a certification path to an accepted trust anchor;

ia-5(2)(a)[3]

includes checking certificate status information when constructing and verifying the certification path;

ia-5(2)(b)

enforces authorized access to the corresponding private key;

ia-5(2)(c)
