58. The holder of a device who has reasonable grounds to believe that the device has been stolen or lost or that its confidentiality is at risk must, as soon as practicable, advise
(1) any person the holder has authorized to use the device ;
(2) any third person who may reasonably be expected to act on the basis of the fact that the device was used by a person authorized to use it ; and
(3) the certification service provider so that the certificate linked to the device may be suspended or cancelled.
An authorized person is bound by the same obligation to advise the holder of the device and the persons referred to in subparagraphs 2 and 3.
No person may use a tangible or logical device to sign a document after learning that the certificate issued for the device has been suspended or cancelled.
