Most of the existing systems are executed with fixed computing logic and rules without the flexibility and smartness to react the dynamic changes of computing situations and environment. Information technology is moving toward a new \"software-defined\" (SD) era that makes the software more \"in command\" of a greater range of devices and hardware systems for computing, storage, transmission, and networking. Software defined systems refer to a collection of enabling software technologies that are emerging in the information technology arena. Examples include Software Defined Networking (SDN), Software Defined Security (SDSec), Software Defined Data Center (SDDC), Software Defined Storage (SDS), and Software-Defined Radio (SDR). Considering their unique features, software development of these systems raises new challenges. In this paper, we plan to design and develop Software-defined Methodologies (SDM) which will be applied to software life cycle. With the support of SDM, we believe SD systems will contain the intelligent characteristics, such as security, reliability, QOS assurance, adaptability, low power consumption, situation awareness... etc.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116732969","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}

Considering the lack of reliability in traditional digital forensics, the authors introduce the idea of a time-space attribute-based evidence fixing method (TAEFM). It fixes digital evidence by generation hash code with fingerprint identification data, trusted time-stamp and e-signature. This system can enhance the credibility of digital evidence and verify whether and which part of evidence was tampered. The location of tampered evidence can be extending to the further forensics.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134619524","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}

Particularly, the MDDs are used to solve traditional coverage models (CMs) where an uncovered component failure may lead to system failure without constraint. This paper presents a new family of decision diagrams, generalized multiple-valued decision diagrams (GMDDs) for the latest irrelevancy coverage model (ICM). In contrast to traditional CMs, the ICM can detect and isolate components whenever they become irrelevant due to the failures of other components, and thus an uncovered component failure can only lead to system failure with the constraint when the component is relevant. Compared with the traditional MDD approach, the GMDD can handle constrained uncovered component failures, and it can incorporate general imperfect fault coverage modelling, including the ICM and traditional CMs.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128511687","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}

Dynamic features in Python allow developers to change the code at runtime. Some dynamic features such as dynamic type checking play an active part in maintenance activities, thus dynamic feature code is often changed to cater to software evolution. The aim of this paper is exploring and validating the characteristics of feature changes in Python. We collected change occurrences in 85 open-source projects and discovered the relationship between feature changes and bug-fix activities. Furthermore, we went into 358 change occurrences to explore the causes and behaviors of feature changes. The results show that: (1) dynamic features are increasingly used and the code is changeable; (2) most dynamic features may behave that feature code is more likely to be changed in bug-fix activities than non-bugfix activities; (3) dynamic feature code plays both positive and negative roles in maintenance activities. Our results provide useful guidance and insights for improving automatic program repair and refactoring tools.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121890438","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}

Our paper uses the attractor and spatial zoom method, and presented the normalized PSO algorithm. Secondly, each attribute is treated equally in the traditional classification algorithm, without considering the differences in attribute measure and contribution, which cause the problem of low classification accuracy. Our paper introduce the use of the normalized PSO algorithm to solve the optimal attribute normalized weighted distance. For example, in KNN classifier, leave-one-out experimental results with multiple UCI data sets show that the classification accuracy using normalization PSO algorithm to calculate normalized weighted distance is higher than using PSO algorithm and traditional none-attribute weighted classifiers.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128035497","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}

However, due to the open nature, P2P streaming systems are vulnerable to malicious attacks, especially data pollution attacks. Reputation-based mechanisms are most effective mechanisms to defend data pollution attacks in P2P streaming systems. In this paper, we propose a dynamic reputation management. In our proposed mechanism, a peer's reputation consists of direct and indirect trust. The confidence factor is used to determine the weight of direct trust. We introduce Gompertz Function to adjust the confidence factor, the more interactions, the larger weight of direct trust value is. Besides, to lower the complexity of calculating indirect trust, we introduce threedegree of separation, which only includes neighbors within three degrees while calculating indirect trust. Simulation results show that our proposed reputation management scheme can effectively separate malicious peers, reduce the dissemination of polluted data chunks and defend various kinds of data pollution attacks.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129591250","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}

To guarantee the correctness of workflow execution, analyses on structural integrity of workflows are essential. However, comparing to the sequential activities, the activities executed in orders, the anomalies caused by parallel activities are far more complicated for analysis. Therefore, separation of concerns among sequential and parallel issues while doing analysis can reduce the complexity among analysis time and human recognition. In this paper, we propose an innovative methodology considering sequential and parallel issues separately within workflow models to detect anomalies in a given workflow. As a result, the cost for anomaly detection is lowered and the complexity for human recognition of the anomaly issues is reduced.","PeriodicalId":114541,"journal":{"name":"2016 Third International Conference on Trustworthy Systems and their Applications (TSA)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131097765","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}
