Publication number: 20170269151Abstract: A method to control aging of a system on chip comprising one or more devices including semiconductor circuit components and at least one aging controller monitoring electrical signals circulating inside the system on chip. The method comprises steps of stressing at least one device of the system on chip by varying hardware parameters related to its operating mode, comparing at least one parameter associated with an electrical signal produced by the at least one device with a reference parameter to determine a difference corresponding to an operating age value of the at least one device, if the operating age value equals or exceeds a threshold age value, determining a stress state value and modifying the operating mode of the at least one device according to the stress state value. A system on chip performing the method is also disclosed.Type: ApplicationFiled: August 18, 2015Publication date: September 21, 2017Applicant: NAGRAVISION S.A.Inventors: Claudio FAVI, Marco MACCHETTI, Karl OSEN

Patent number: 9055665Abstract: The present invention may be deployed in a system comprising a security module housed on a chip card and a host device comprising a chip card reader. The host device is comprised in a housing with a slot for the chip card. The housing is shielded to reduce the amount of electromagnetic radiation generated by the security module and/or the host device from penetrating to the exterior of the housing. Similarly, the shielding is adapted to reduce the effects of electromagnetic radiation generated outside of the host device on the components within the housing. The slot is also shielded by a flap made of an electrically conductive epoxy material or an electrically conductive resin.Type: GrantFiled: November 17, 2011Date of Patent: June 9, 2015Assignee: NAGRAVISION S.A.SInventors: Karl Osen, Ernest Odoom

Patent number: 8733652Abstract: The present invention may be deployed in an interface between a security module (CH) housed on a chip card (CC) and a host device (HST) comprising a chip card reader (RDR). In the case where the security module (CH) operates at frequencies which are high enough to generate unwanted electromagnetic interference, the invention allows for a substantial reduction in such interference by providing a converter module (CVT) which allows the host device to operate at lower frequencies while a limited number of short, shielded connections are used to interface with the security module (CH).Type: GrantFiled: November 17, 2011Date of Patent: May 27, 2014Assignee: Nagravision S.A.Inventors: Karl Osen, Ernest Odoom

Patent number: 8656204Abstract: Example embodiments relate to a security device having two communication interfaces sharing at least one pin, each interface being capable of operating according to either of two predetermined communication protocols. The security device may further include a frequency detector to detect the frequency of a clock signal on the shared pin. Depending on the value of the detected frequency, and to which of a plurality of predetermined frequency ranges the detected frequency pertains, the security device may function according to one of the two predetermined communication protocols, operating at two different frequencies.Type: GrantFiled: June 25, 2010Date of Patent: February 18, 2014Assignee: Nagravision S.A.Inventors: Karl Osen, Nicolas Fischer

Patent number: 7926050Abstract: Transmission method of a message containing a program block that avoids the consequences of a possible malicious decryption of this message is proposed. This is achieved through a secure method to update software embedded in a security module, comprising formation of a first updating program block, determination of a target memory zone of said security module, determination, through said security module, of a pre-registered content in said target memory zone, formation of a second program block obtained by the mixing of all or a part of the pre-registered content with the first program block, transmission of the second program block to the security module, reception of the second block by the security module, reading of the target memory zone, obtaining and writing in the target memory zone of the first block by the inverse mixing of all or part of the second block and of the target memory zone content.Type: GrantFiled: June 8, 2005Date of Patent: April 12, 2011Assignee: Nagravision S.A.Inventor: Karl Osen

Publication number: 20110010574Abstract: The invention relates to a security device intended to be connected to a processing unit for an audio/video signal. This device comprises means to decrypt an audio/video stream, an interface of the ISO 7816 type and at least one high speed serial communication interface. It is characterised in that it includes a clock frequency detection module connected to a clock input of the 7816 interface, this detection module comprising means to distinguish the input frequency according to at least two different frequency ranges, the different frequency ranges activating the different communication functions. The invention also concerns a process for processing an audio/video signal by means of a security device comprising means to decrypt an audio/video stream, an interface of the ISO 7816 type and at least one high speed serial communication interface.Type: ApplicationFiled: June 25, 2010Publication date: January 13, 2011Inventors: Karl Osen, Nicolas Fischer

Publication number: 20040233288Abstract: A system is for selecting filmed sequences acquired by several cameras pointing at fixed or mobile objects. The sequences are sent to a processing center. This processing center receives the data describing the behavior of the objects and affects the choice of sequences to be broadcast. Each camera takes sequences of which the positions in the visual environment are defined by captors measuring aiming angles and angles of view, which are transmitted to the processing center including a database qualifying the acquired sequences and enabling the creation of a sequence rating as a function of the portions of the visual environment which have been filmed and the behavioral data of the objects. Once this information has been processed by the processing center, the processing center has the means to select the sequence with the highest rating.Type: ApplicationFiled: June 4, 2004Publication date: November 25, 2004Inventors: Mario Hytten, Karl Osen

Publication number: 20040105010Abstract: A computer aided filming system, allowing to acquire images from at least one camera of a moving target (2, 3). This target moves within known geographical and physical boundaries. The system according the invention comprises pointing means to point at the moving target, computation means which determine the position of the moving target based on the pointing angles of the said pointing means and the corresponding boundary data, thus allowing said computation means to determine the pointing angles and the focus of at least one camery. The pointing means could be the main camera, an eye position sensor coupled with a head position sensor or an operator pointable structure with pan and tilt sensors.Type: ApplicationFiled: December 30, 2002Publication date: June 3, 2004Inventor: Karl Osen
