Latest Patents

One of Yves Magnaud's latest patents focuses on the protection of an authentication method. This invention involves a device that executes an authentication process safeguarded by an authentication counter. The counter increments in the event of an authentication failure, and its incrementation is protected against unexpected device power-off or power-off attacks. The non-volatile memory is divided into pairs of cells, where a fixed value D is written into an active pair of two consecutive cells. Successful authentications lead to the first cell being overwritten by a random value, while failed authentications result in the second cell being overwritten and the next two consecutive cells being written with the fixed value D. This mechanism effectively prevents the lack of incrementation of the authentication counter during unexpected power-offs.

Another significant patent by Magnaud pertains to I2C communication. This method involves a communication process via the I2C bus between an emitting device and a receiving device. It records a rising edge of a clock signal of the I2C bus that directly follows a start condition of the communication. When an interruption occurs within the receiving device, it verifies whether the rising edge was recorded, enhancing the reliability of the communication process.
