If a plaint image contains some groups of identical colors, then the encrypted cipher image may appear some kinds of patterns at the related areas. This is a limitation of AES in ECB mode. To overcome the limitation, a straight forward approach is to make those identical colors different or to remove them. For making those inputs different before encryption, three number sequences, which are the sequential number from counter output, the non-sequential number from accumulator output and the random numbers generated from cipher function itself, are added to the image inputs. By using the different numbers and the different ways of addition, the modifications result in obtaining seven modes of operation, and four of them were defined in NIST publications. To remove the identical inputs, image compression before encryption is used. Though by adding compression and decompression seems to make the whole process more complicated, yet the processing time decreases due to the shrinking file size after image compression. These two approaches to modify ECB operation work very well as shown in the experiments.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126253911","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}

The error diagnosis component is useful for evaluating students' errors and is performed for all the system's supported languages.

This can lead to the profile owners being vulnerable to social engineering attacks. Our vulnerability model is based upon a way to quantify the vulnerability of a profile and consists of three components. The individual vulnerability is determined by the presence of values for the profile attributes which may contribute towards the composite personal vulnerability via a weight based system. The relative vulnerability indicates the contribution of collective vulnerability of the profile's friends, whereas the absolute vulnerability is the overall composite vulnerability for the profile by considering the contributions of the individual and relative vulnerabilities. In this paper we introduce a set of axioms on probability dependent effect of profile attributes and probability change for OSN profiles. The research offers a formal background for future work on estimating how attribute changes for an OSN profile influence the individual vulnerability of the profile and validating this composite model.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124564132","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}

That necessitates allocation of large amount of data storage in computer systems. Commonly, relational database management systems (RDBMS) are used for managing those data. However, an algorithm should be implemented to map multi-dimensional data to one-dimensional data in RDBMS. We found that a group of researchers worked on this problem and solved with SPIT (Space-Partitioning with Indexes on Time) approach [Mallett 2004]. SPIT partitions space according to sweep-space filling curve and the researchers argue that using sweep-space filling curve puts lesser demands on I/O than z-order space filling curve. Accordingly, researchers suggest using the former method for storing and indexing of spatio-temporal data. In this paper, we present the results of a series of experiments where we partitioned space by z-order space filling curve and used a sliding window technique for tracking of moving objects. We suggest that in the cases where the tracked objects are close to each other, we can obtain better performance from z-order partitioning than sweep-space filling curve by using sliding window technique for tracking of moving objects.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115008925","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}

The security protocols used in these wireless networks rely on stream cipher to encrypt data before being transmitted. These protocols are secure but they don't respect the real-time requirement of industrial control. Chaotic systems are able to produce stream cipher with higher randomicity, which looks like stochastic noise. Based on two perturbed piecewise linear chaotic map (PWLCM), we propose a new high speed chaotic cryptographic scheme. It requires a little memory capacity, and also appears to be very secure. The proposed generator is easily realized and succeeds all the statistical tests. In this paper, we will explain briefly the design of our proposed generator and show its efficiency through encryption tests.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121306923","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}
