摘要： 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.

摘要： A first and second set of simulation information of a circuit design may be received. Energy consumption values associated with signals may be calculated for each of the first and second sets of simulation information of the circuit design. The energy consumption values associated with the transitions of the plurality of signals for each time point of a plurality of time points may be aggregated based on when each of the transitions of the signals occurs for each of the first and second sets of simulation information. Furthermore, a possible Differential Power Analysis (DPA) leak may be identified at one of the time points based on a difference in aggregated energy consumption values between the first and second sets of simulation information.
摘要翻译：可以接收电路设计的第一和第二组仿真信息。可以针对电路设计的第一组和第二组模拟信息中的每一个来计算与信号相关联的能量消耗值。可以基于对于第一和第二组模拟信息中的每一个发生信号的每个转换何时聚合与多个时间点中的每个时间点的多个信号的转变相关联的能量消耗值。此外，可以基于第一组和第二组模拟信息之间的聚合能量消耗值的差异在一个时间点上识别可能的差分功率分析（DPA）泄漏。
