This paper presents a restructuring approach to relocating web page composition from servers to browsers for Java web applications. The objective is to reduce redundant manipulation and transfer of code/data that are shared by web pages. The reduction is carried out through a restructuring algorithm, effectively keeping consistency between source and target applications from the perspective of the...
To solve the issues of user data security and sharing in the cloud storage environment, we studied the methods to build an encrypted cloud storage system with sharing mechanism. This paper provides a method to build such a system on the basis of the existing OpenStack Swift storage service. Then the architecture design of this system is given, which includes the use of the combination of public-key...
This article puts forward a web crawler model of fetching data speedily based on Hadoop distributed system in view of a large of data, a lack of filtering and sorting, and other reasons which cannot make the web crawler timely and effectively get data index of the Internet in the current network environment. The crawler model will transplant single-threaded or multi-threaded web crawler into a distributed...
MQ-based cryptosystems have the potential to resist future quantum computer attacks, and can be efficiently implemented. We investigate the side channel attacks against MQ-based cryptosystems in this paper. For MPKCs, which are based on solving multivariate quadratic system, there isn't side-channel leakage found for their major computation components. For Cryptosystems based on calculating multivariate...
Variable selection is very important for interpretation and prediction, especially for high dimensional datasets. In this paper, a new method is proposed based on Random Forest (RF) to select variables using Mean Decrease Accuracy (MDA) and Mean Decrease Gini (MDG). We also use dichotomy method to screen variables, which is proved to perform very fast. Experiments on 10 microarray datasets show that...
