    • A method of cryptographic processing of data (X), in particular a method protected against fault injection attacks, and an associated device. The processing includes at least one transformation (100, 1001-1006) of an input data item (s) into a result data item (s′). In this case the method includes a step (E204) of verifying the transformation including the following steps: obtaining (E206) a first data item (DV(s′)) that is compressed by applying a compression operation (110, MDV, ADV) to the result data item (s′); obtaining (E208) a second compressed data item (DV(s)) that is compressed by applying the compression operation (110, MDV, ADV) to the input data item (s); determining (E210) a verification data item (DV(s)′) by applying the transformation (100, 1001-1006) to the second compressed data item (DV(s)) and; comparing (E212) the verification data item and the first compressed data item.
    • 该方法包括进行变换,例如。 将输入数据项的乘法逆变换(MIT)转换成结果数据项。 获得通过对结果数据项应用压缩操作来压缩的数据项。 获得通过将操作应用于输入数据项而压缩的另一数据项。 通过将变换应用于后一个压缩数据项来确定验证数据项。 将验证数据项和前一压缩数据项进行比较,以验证输入数据项到结果数据项的变换。 还包括用于数据的密码处理的设备的独立权利要求。

    • A management process for access to secure data includes: storing secure data associated with a first user and authentication data of said first user, managing access to the secure data of the first user, as a function of the authentication data of this first user. The process includes: storing, in the secure data of the first user, a heritage rule and a list of at least one second user and, for each second user of said list, an rule for access to secure data of the first user, storing authentication data for each second user of said list, and when the heritage rule is satisfied, managing access, by said at least one second user, to the secure data of the first user, as a function of the authentication data of the second user and of the rule for access of the second user.
    • 用于访问安全数据的管理过程包括:存储与第一用户相关联的安全数据和所述第一用户的认证数据,根据该第一用户的认证数据来管理对第一用户的安全数据的访问。 该过程包括:在第一用户的安全数据中存储遗产规则和至少一个第二用户的列表,并且对于所述列表的每个第二用户,存储用于访问第一用户的安全数据的规则,存储 所述列表的每个第二用户的认证数据,以及当满足遗产规则时,根据所述第二用户的认证数据来管理所述至少一个第二用户对所述第一用户的安全数据的访问,以及 的第二用户的访问规则。

    • A method and device for controlling the execution of at least one function in a short-range wireless communication module of a mobile apparatus adapted for receiving at least one identification card. After transmitting an information request to the identification card, to obtain at least one piece of information characteristic of the identification card, an answer including at least one piece of information characteristic of the identification card is received therefrom. When the answer is identified and in response to the at least one piece of information, the at least one function is executed. An authentication request is received by the short-range wireless communication module. If the answer is authenticated, the short-range wireless communication module sends an authorization to the authentication request in response to the at least one piece of information characteristic of the identification card before the execution of the at least one function.
