description A method is provided for authenticating a first device to a second device using a self-signed digital certificate, when the first device is requested to authenticate itself to the second device. Responsive to the request, a self-signed digital certificate is sent from the first device to the second device. The self-signed digital certificate includes a hash of a password that has been previously provisioned in the first device. The password previously provisioned in the first device is hashed. The hash of the password previously provisioned in the first device is compared, using the second device, with the hash of the password included in the self-signed digital certificate. The first device is authenticated if the second device confirms that the hash of the password previously provisioned in the first device matches the hash of the password included in the self-signed digital certificate.
