Abstract
A secure element (SE) determines a profile type and a privilege level. The privilege level, in some embodiments, is associated with a key used successfully by the SE to verify a cryptographic signature. In some embodiments, the privilege level is indicated by a privilege value read from an extension field of a root certificate. The SE determines, in some instances, whether to accept or reject a profile installation after comparing the profile type with the determined privilege level. Thus, a test server is allowed to provision a test profile to an SE even if the test server does not have commercial certification required of an electronic subscriber identity module (eSIM) server that provisions operational profiles. Because the test profile does not include credentials useful for network access, the lower-security test server does not create a risk of improper access to the network of a mobile network operator (MNO).
