    摘要: The invention relates to a method for authenticating a plurality of slave devices (D1-D3) connected to a master device (CPU), including the steps consisting in: the master device generating and sending a respective challenge (c1-c3) to each slave device; a response (r1-r3) to the respective challenge being generated in each slave device and sent to the master device; the master device verifying the response (r3) of one of the slave devices (D3); the master device returning the remaining responses to respective slave devices other than those that generated the responses; and each slave device (D2, D3) verifying the response that was returned to it by the master device and transmitting the result of the verification to the master device.

    摘要: L'invention concerne un dispositif (ND1) d'émission de données par couplage inductif, comprenant un circuit d'antenne inductif accordé (ACT) et un circuit de modulation d'amplitude (MCT1) pour appliquer au circuit d'antenne des salves (B3) d'un signal périodique (Slm), l'amplitude de chaque salve étant délimitée par un signal d'enveloppe présentant un front montant et un front descendant. Selon l'invention, le circuit de modulation est configuré pour conformer au moins le front descendant du signal d'enveloppe de manière que la dérivée première du front descendant soit continue, pour atténuer ou supprimer des oscillations transitoires du signal d'antenne pouvant être générées par l'application au circuit d'antenne des salves du signal périodique.

    摘要: The method involves executing multiple loops of an encrypting algorithm on data of an input message, to obtain processed message data results. Each loop is executed by using a different masked key among masked keys until all the masked keys are used once, where the execution of the loop using authentic and dummy keys produces authentic and dummy message data results, respectively. The authentic and dummy data results are stored in respective locations of a memory.

    摘要: A fault detection method for an encryption/decryption system based on a block cipher comprises the steps of subjecting a state array (CST) to multiple rounds, each round comprising a same series of sequential operations transforming the state array; storing the state of a reference operation (ShiftRows) of a current round as a checkpoint state (CHK); storing the state of the reference operation in the next round as an intermediate state; applying one round of reciprocal operations to the intermediate state, starting from the reciprocal of the reference operation (InvShiftRows); and comparing the result state of said one round of reciprocal operations with the checkpoint state.
