Abstract
Embodiments of the invention are directed to techniques for enabling self-certification of an electronic device to result in the issuance of a security certificate that the electronic device may use to authenticate itself to another entity. In some embodiments, the device is caused to initiate the self-certification process upon determining that a status of a current security certificate is no longer valid. In some embodiments, an electronic device may communicate with a certificate authority, which may generate a set of policy data that indicates permissions for the electronic device. The electronic device may then generate an electronic record to be associated with the security certificate, which it may sign using a private key. The certificate authority may then verify the authenticity of the signed electronic record using a public key associated with the electronic device. The electronic record may be appended to some collection of records.
