Patent number: 10404719Abstract: Method for verifying data generated by an electronic device included in equipment, the electronic device including a computing unit, a one-time programmable memory and a volatile memory, the equipment including a rewritable non-volatile memory and a communication bus enabling the electronic device to store data in the rewritable non-volatile memory. The method includes: creating a secured channel by encryption between the equipment and a server; obtaining an authentication key from the server; loading data and a message authentication code from the rewritable non-volatile memory to the volatile memory, the message authentication code obtained by the electronic device from the authentication key and said data prior to the storage of said data and message authentication code in the rewritable non-volatile memory, the electronic device not having kept the authentication key following the obtaining of the message authentication code; verifying said data using the secret key and the message authentication code.Type: GrantFiled: November 21, 2017Date of Patent: September 3, 2019Assignees: IDEMIA IDENTITY & SECURITY FRANCE, STARCHIPInventors: Jean-Yves Bernard, Yves Fusella, Maël Berthier, Lauren Del Giudice

Patent number: 9167460Abstract: Described are methods and devices for detecting cable network interference on a wireless network. In one aspect, disclosed is a method, performed by a processor of a cable interference detection device, of detecting interference in a wireless network caused by a cable network. The method includes: obtaining a signal signature of a wireless signal received at a receiver of a mobile communication device, the signal signature being a fast fourier transform representation of the wireless signal; and determining that the wireless signal represents interference caused by the cable network by comparing the signal signature to a cable network signal signature.Type: GrantFiled: June 28, 2013Date of Patent: October 20, 2015Assignee: ROGERS COMMUNICATIONS INC.Inventors: Jean-Yves Bernard, George Maynard Hart, Edward A.
