    • A method is provided for securing a microprocessor containing at least one main program, which operates with at least one memory. The method includes implementing counter-measures, during which additional operations, that are not required for the main program, are implemented so as to modify the consumption of current and/or the processing time of the microprocessor. The method also includes: identification of at least one address or one memory zone of the memory(ies), called critical addresses, and which contain, or which may contain, critical data for said main program; monitoring the addressing ports of the memory(ies), so as to detect the access to the critical address(es); and activation of the step of implementing counter-measures, when an access to the critical address(es) is detected.
    • 提供了一种用于固定包含至少一个主程序的微处理器的方法,所述至少一个主程序与至少一个存储器一起操作。 该方法包括实现对策,在此期间实施主程序不需要的附加操作,以便修改微处理器的当前和/或处理时间的消耗。 该方法还包括:识别存储器的至少一个地址或一个存储器区域,称为关键地址,并且其包含或可以包含用于所述主程序的关键数据; 监视存储器的寻址端口,以便检测对关键地址的访问; 以及当检测到对关键地址的访问时,激活实施对策的步骤。

    • A data processing system having a first processor, a second processor, a local memory of the second processor, and a built-in self-test (BIST) controller of the second processor which can be randomly enabled to perform memory accesses on the local memory of the second processor and which includes a random value generator is provided. The system can perform a method including executing a secure code sequence by the first processor and performing, by the BIST controller of the second processor, BIST memory accesses to the local memory of the second processor in response to the random value generator. Performing the BIST memory accesses is performed concurrently with executing the secure code sequence.
    • 一种具有第一处理器,第二处理器,第二处理器的本地存储器和第二处理器的内置自检(BIST)控制器的数据处理系统,其可以被随机地启用以对本地存储器执行存储器访问 的第二处理器,并且包括随机值发生器。 该系统可以执行包括由第一处理器执行安全代码序列并且由第二处理器的BIST控制器响应于随机值生成器对第二处理器的本地存储器进行BIST存储器访问的方法。 执行BIST存储器访问同时执行安全代码序列。

    • A method of and system for gate-level masking of secret data during a cryptographic process is described. A mask share is determined, wherein a first portion of the mask share includes a first number of zero-values and a second number of one-values, and a second portion of the mask share includes the first number of one-values and the second number of zero-values. Masked data values and the first portion of the mask share are input into a first portion of masked gate logic, and the masked data values and the second portion of the mask share are input into a second portion of the masked gate logic. A first output from the first portion of the masked gate logic and a second output from the second portion of the masked gate logic are identified, wherein either the first output or the second output is a zero-value.
