PRINCE is a 64-bit lightweight block cipher with a 128-bit key published at ASIACRYPT 2012. Assuming one nibble fault is injected, previous different fault analysis(DFA) on PRINCE adopted the technique from DFA on AES and current results are different. This paper aims to make a comprehensive study of algebraic fault analysis(AFA) on PRINCE. How to build the equations for PRINCE and faults are explained. Extensive experiments are conducted. Under nibble-based fault model, AFA with three or four fault injections can succeed within 300 seconds with a very high probability. Under other fault models such as byte-based, half word-based, word-based fault models, the faults become overlapped in the last round and previous DFAs are difficult to work. Our results show that AFA can still succeed to recover the full master key. To evaluate security of PRINCE against fault attacks, we utilize AFA to calculate the reduced entropy of the secret key for given amount of fault injections. The results can interpret and compare the efficiency of previous work. Under nibble-based fault model, the master key of PRINCE can be reduced to 29.69 and 236.10 with 3 and 2 fault injections on average, respectively.

语音分类是语音信号处理的重要组成部分。准确快速地对语音进行分类在语音编码、语音合成中有着重要的意义。针对当前一些常用分类特征和分类算法的不足,本文提出一种利用语音的Mel频率子带能量作为分类特征,建立高斯混合模型(GMM),运用最大后验概率准则对清音、浊辅音、元音分类的算法。仿真实验表明,在噪音环境下该算法仍可准确进行语音信号分类。

Ever since the 1960s, along with the decline of logical empiricism, the philosophy of science has undergone a number of fundamental changes： its theoretical space has broadened from a context valuing defense to one that values discovery, its methodology has broadened from logical analysis of scientific narration and concepts to contextual analysis stressing scientific practice; its fundamental tenets have changed from rejection of metaphysics and advocacy of the dichotomy of theory and observation to the holistic tenet of observation permeating theory; and its research field of vision has also changed from a static analysis of theoretical structures to a dynamic analysis of theoretical changes and laboratory work from the angle of science history and sociology. However, confronted with the dilemma that has entrapped logical empiricism, philosophers of science have not, until now, provided any new approach that has been universally approved. Now, having recognizedthe status quo, dilemmas and trends of development of the philosophy of science in the contemporary world, from what base point should we set out to seek solutions to these dilemmas and decide the starting point for the development of the philosophy of science？ How should the historical, social, cultural and psychological aspects of science be integrated into an irreversible and holistic base point？ This important and unavoidable question must arise when one explores trends in the development of the philosophy of science today.
