多輸出前饋函數(shù)的一種相關(guān)分析方法
CRYPTANALYSIS ON MULTI-OUTPUT FEEDFORWARD NETWORK SYSTEM
-
摘要: 本文提出了分析多輸出前饋網(wǎng)絡(luò)的一種方法,該方法的基本思想是收集輸入信息在多個(gè)輸出端上的信息泄漏,從而達(dá)到更充分地利用所有泄漏的信息的目的。作為應(yīng)用,利用文中給出的方法分析了一類重要的多輸出前饋網(wǎng)絡(luò)一多輸出Bent函數(shù),并用一個(gè)具體實(shí)例說明了這種方法的全過程。

Abstract: An algorithm analysing multi-output feedforward network system is discussed in this paper, the basic idea of the algorithm is to collect and utilize information leak of input information at multiple output ends. As an application, a class of important multi-output feedforward network-multi-output Bent functions is analysed by using the algorithm, and the algorithm is illustrated with a concrete example. -
