Patent number: 10237730Abstract: Disclosed herein are methods and systems for encrypting communications using a secure element. An embodiment takes the form of a method including the steps of performing a key-exchange procedure with an endpoint via a voice-communication device to obtain a symmetric seed key for a secure voice session with the endpoint; generating first and second symmetric session keys for the secure voice session based on the obtained symmetric seed key; receiving outbound voice packets from the voice-communication device in connection with the secure voice session, each outbound voice packet including a header and an unencrypted payload; using a first symmetric encryption algorithm and the first symmetric session key, followed by a second symmetric encryption algorithm and the second symmetric session key to generate and output twice-encrypted outbound-voice-packet payloads to the voice-communication device for transmission to the endpoint in connection with the secure voice session.Type: GrantFiled: May 10, 2016Date of Patent: March 19, 2019Assignee: NAGRAVISION S.A.Inventors: Bernard Benoit, Jean-Claude Fournier, Jerome Perrine, Laurent Gauteron

Patent number: 4121136Abstract: Apparatus for feeding a discharge lamp such as a mercury vapor lamp mounted in series with a choke from a direct current source comprising a chopper of direct current including an electronic switch and a detector of current intensity mounted in series with the choke. A first comparator compares the intensity of the current to a maximum level for opening the switch when the maximum level is reached and a second comparator compares the intensity of the current to a minimum value for closing the switch when the minimum value is reached. The lamp choke and current detector are connected in series with one another and a diode is mounted in parallel therewith and is oriented in the direction to pass current from the negative terminal towards the positive terminal of the direct current source.Type: GrantFiled: May 12, 1977Date of Patent: October 17, 1978Assignee: Etat FrancaisInventors: Jean-Claude Fournier, Albert Hermitte
