Next, aimed at the AES(128 bits) cryptographic system realized by the P89C668 microcomputer, Differential Electromagnetic Analysis (DEMA) algorithm was described, the choosing of attack point and the computational method were analyzed, an attack experiment was processed by DEMA, thereby obtaining secret key of AES(128 bits). After analyzing the experiment result at the instruction level, we find that the most serious leakage of secret information happens in the MOVX instruction which writes the output of S-box into external RAM. The result shows that EM information leakage exists in CMOS integrated circuit during work. DEMA is an effective attack on AES. It can provide a basis for implementing protective measures in the cryptographic systems.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126139716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clustering analysis plays very important role in mining the data. The grey trend relation (GTR) clustering involved in the grey trend relation system is a good way to find the poor information in order to find the useful information to make decision, which is also an implement and development in data mining. Combining with the grey trend relation and using the general mathematical system theory, the GTR system model are setup. Through analyzing the data of sale system, it is can be seen that some different commodities in sale increment are similar and there are a few of different classification.

The parametric quadratic programming problem causes much more computation than the common quadratic programming problem. We employ the parametric pivoting algorithm to improve the computing efficiency of the parametric quadratic programming problem. The algorithm can decrease calculation to obtain solution of quadratic programming problem by solving a small linear inequality system which is the linear part of the Karush-Kuhn-Tucker (KKT) conditions for the quadratic programming problem and is equivalent to the KKT conditions while maintaining complementarity conditions of the KKT conditions to hold. The key of the algorithm is the deduction of the parametric formula which can obtain the optimal solution of the problem under new value of the parameter more efficiently by making full use of the information of the obtained optimal solution to the problem under former value of the parameter. The parametric formula further decreases the computation of the optimal solutions under different value of parameter.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130985453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
