Abstract
The disclosed embodiments related to a first electronic device (such as a cellular telephone) that includes a secure element. In response to a challenge and a request for a secure-element identifier associated with the secure element, which are received from a second electronic device (such as a trusted services manager that loads content onto the secure element), the secure element provides to the second electronic device: the secure-element identifier, a certificate associated with a provider of the secure element, and a digital signature. The digital signature may include a signed version of the challenge and the secure-element identifier, which are encrypted using an encryption key associated with a provider of the secure element. In this way, the second electronic device may certify the secure element.
