Patent number: 11405190Abstract: A method for setting up a subscriber identity module for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server includes generating one or several exchange keys from keys of the provisioning server and of the subscriber identity module on a production server and are transmitted into the subscriber identity module and stored, so that the subscriber identity module is put particularly into a state as though it had generated the exchange keys itself. In a method for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server, the subscriber identity module sends its public key to the provisioning server, which subsequently generates the exchange keys.Type: GrantFiled: December 14, 2016Date of Patent: August 2, 2022Assignee: GIESECKE+DEVRIENT MOBILE SECURITY GMBHInventors: Gabriel Goller, Sven Bauer, Jürgen Pulkus, Lars Hoffmann

Patent number: 11386239Abstract: A method for the transition is provided from a Boolean masking of a value to be kept secret to an additive masking of the value to be kept secret. The value to be kept secret is present in the Boolean masking as a representation masked with a first Boolean mask and a second Boolean mask. A first additive mask and a second additive mask are determined for the value to be kept secret. A first masking transition is executed in which the first Boolean mask is converted into the first additive mask. A second masking transition is executed in which the obfuscation value is converted into an additive correction value, and a third masking transition is executed in which the second Boolean mask is converted into the second additive mask.Type: GrantFiled: February 28, 2018Date of Patent: July 12, 2022Assignee: GIESECKE+DEVRIENT MOBILE SECURITY GMBHInventors: Jürgen Pulkus, Lars Hoffmann

Patent number: 11321706Abstract: The invention provides a method that allows an issuer system, e.g. of a bank, to have generated a plurality of anonymous accounts and cards for working up a stock and to only personalize them individually if required. In the personalization step at the card issuer, e.g. in the bank branch, a printing of the back side does not have to be performed, instead all the necessary printing of the back side is already effected at the card manufacturer during the manufacturing of the anonymous card. As a result, a simple, low-cost printer without a back-side printing option can be utilized for the personalization of the anonymous card.Type: GrantFiled: March 21, 2018Date of Patent: May 3, 2022Assignee: GIESECKE+DEVRIENT MOBILE SECURITY GMBHInventor: Christian Boelle

Patent number: 11267277Abstract: A method for manufacturing a physical security element with a spatially appearing pattern includes a carrier and at least one see-through transparent cover layer. Onto the carrier is applied a design layer deformable under pressure. Either the carrier has a lower dimensional stability under heat than the cover layer, or a cover layer has a lower dimensional stability under heat than the carrier. A see-through transparent structural layer forming the pattern is arranged between carrier and cover layer. The structural layer has a higher dimensional stability under heat than either the carrier or a cover layer. During lamination, the structural layer is pressed into the carrier or into the cover layer, whereby the design layer is deformed under the pattern formed by the structural layer and the structural layer in its edge regions is reshaped in such a way that its surfaces, in cross-section, converge tangentially.Type: GrantFiled: June 22, 2018Date of Patent: March 8, 2022Assignee: GIESECKE+DEVRIENT MOBILE SECURITY GMBHInventors: Juan Nunez, Oliver Muller
