Abstract: Various embodiments relate to a method, device, and non-transitory medium including: determining a master key value for use in secure communications with a different device, wherein the master key value is used as a master key; deriving at least one session key using the master key; generating a new master key value based on the master key; deleting the current master key value; and using the new master key value as the master key.

Abstract: A data processing apparatus (30) comprising: a local source of data (4); a first controller (31); and a tamper-resistant second controller (32) configured to communicate with the first controller, the first controller being configured to control and receive data from the local source of data and from a sensing unit connected to the first controller via a communication interface and to perform a series of calculation operations on the data, wherein the second controller is configured to verify the integrity of a selected subset of the operations performed by the first controller.

Abstract: A method of manufacturing a semiconductor device is provided. The method includes providing a transparent substrate having predefined active regions and non-active regions. Thereafter, the method includes spraying droplets of a lacquer on the predefined active regions to form corresponding lacquer layer regions, such that the non-active regions do not have presence of the lacquer. The lacquer layer regions are of a predefined thickness to enable their functional texturing. Texturing of lacquer layer enables light trapping or light extraction. Thereafter, one or more semiconductor layers are deposited o the lacquer layer regions and a cover substrate is provided. The cover substrate is joined to the transparent substrate at a portion of the non-active regions and encapsulates the lacquer layer regions and the one or more semiconductor layers between itself and the transparent substrate.

Abstract: A road pricing smart client and method for a road pricing system enabling the removal of information from the positioning data describing the itinerary which suggest private data such as travelling speed and itinerary of the originator of the data. Accordingly, the smart client and method is configured to re-sample the original positioning points of the route into equidistant sections, remove timing information from the positioning data, slice the re-sampled route into slices shaped as those provided by other road users by employing a common “virtual grid”. By transmitting the slices in randomized order with an arbitrary delay, coherence of slices corresponding to formerly neighboring portions of the itinerary, are not correlated anymore. However, there is still enough information provided to the toll system to send an excerpt of the fee database allowing the smart pricing client or method to calculate the occurred fees.
