Abstract: A provisioning security device, such as a Hardware Security Module, is configured to be coupled to a provisioning apparatus. The provisioning apparatus is electrically connectable with at least one electronic device for provisioning the electronic device in a provisioning session with provisioning data using a serial communication protocol of the electronic device. The provisioning security device comprises processing circuitry configured to generate a provisioning script for executing a portion of the provisioning session. The provisioning script defines a sequence of a plurality of commands of the serial communication protocol used by the electronic device and comprises a portion of the provisioning data. Moreover, the provisioning security device comprises a communication interface configured to transmit the provisioning script to the provisioning apparatus. Furthermore, a correspondingly configured provisioning apparatus is disclosed.

Abstract: A method (100) of demodulating a real two-dimensional pattern (110) is disclosed. The method (100) estimates (120, 130) a quadrature two-dimensional pattern from the real two-dimensional pattern (110) using a smooth phase only transform having an anti-symmetric phase, such as a spiral phase filter (140). A demodulated image is created by combining (180) the real two-dimensional pattern (110) and the estimated quadrature two-dimensional pattern.
