  • Patent number: 10404719
    Abstract: 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.

  • Patent number: 9286207
    Abstract: The invention relates to a method for managing the endurance of a data storage system provided with a set of sectors endowed with a guaranteed native endurance capacity (G), comprising the steps consisting in: —partitioning said data storage system into a plurality of work sectors, and into a plurality of replacement sectors able to form an endurance reservoir, certain of the work sectors being intended to be replaced by replacement sectors when said work sectors are expended after a certain number of programming and/or erasure cycles; —defining an address management area making it possible to retrieve the location of the replacement sectors assigned to expended work sectors; —determining, sector by sector, whether a current work sector is physically expended, and executing a step of replacing this work sector by a replacement sector, only when said current work sector is declared physically expended.

  • Patent number: 8248955
    Abstract: Each of a plurality of serially-connected data transmission apparatuses comprises a first shift register, a fault-detecting circuit and a second shift register. The second shift register is configured to receive a second serial input signal and generate an output signal according to a clock signal. The fault-detecting circuit is configured to select one of the outputs of the second shift register and a first serial input signal based on the fault-detecting result. The first shift register is configured to receive the output of the fault-detecting circuit and generate an output according to the clock signal. The second serial input signal is equal to the first serial input signal of at least one preceding stage, and the first serial input signal is equal to the output serial signal of the preceding stage. One purpose of the present invention is to maintain continuous transmission of the serial data when a failure of the serially-connected data transmission apparatus occurs.
