摘要： A masking addition operation apparatus for prevention of a side channel attack, includes a random value generation unit generating a first random value for a first input, second random value for a second input, and a summation random value. The masking addition operation apparatus includes an operation part performing an operation on the first and second random values, a previous carry input, and first and second masked random values generated based on the first and second random values. The masking addition operation apparatus includes a carry generator generating a carry input using a result of the operation part; and a summation bit generator generating a summation bit using the summation random value, the first and second random values, the previous carry input and the first and second masked random values.

摘要： In a method of allocating a bandwidth of a passive optical network, downward data are transmitted by varying a wavelength based on a wavelength division method and upward data are transmitted using a time division method. Thereby, by efficiently allocating a network bandwidth, data can be transmitted and by realizing statistical multiplexing, transmission efficiency can be improved.

摘要： Disclosed are an apparatus and a method for separating sound sources capable of learning distributions of corresponding sound sources based on the assumption that specific sound sources have specific distributions based on interchannel correlation parameter in audio signals providing space perception through a plurality of channels to separate an amount corresponding to energy contribution of the corresponding sound sources from mixture signals. Exemplary embodiments of the present invention can more precisely predict the channel distributions of the specific sound sources included in the input mixture signals and more accurately separate sound sources than a method for separating a sound source based on the channel according to the related art, under conditions that general channel distribution information of the specific sound sources are approximately modeled.
摘要翻译：公开了一种用于分离能够学习相应声源的分布的声源的装置和方法，所述设备和方法基于以下假设：特定声源具有基于通过多个声道提供空间感知的音频信号中的通道间相关参数的特定分布，以分离数量对应于来自混合信号的相应声源的能量贡献。本发明的示例性实施例可以根据现有技术更准确地预测包括在输入混合信号中的特定声源的信道分布和更准确地分离声源，而不是根据现有技术在信道上分离声源的方法特定声源的通用通道分配信息被大致建模。
