Cloud computing is being adopted in critical sectors such as energy, transport and finance. This makes cloud computing services critical in themselves. When cyber-attacks and cyber disruptions happen, millions of users are affected. Infrastructure vendors will inevitably take advantage of the benefits offered by the cloud computing environment, but while this may offer improved performance and scalability, the associated security threats deter this progression. There needs to be an assurance that confidentiality, integrity and availability of the data and resources is maintained. This paper provides an overview to the cloud security conundrum, details existing intrusion detection methods, and presents our observation and proposed elastic scaling method for cloud security.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116339135","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}

It shows that the cryptosystem under study has weak diffusion and presents a cryptanalysis that allows the attacker to decrypt any encrypted image. More precisely, it proposes a divide-and-conquer attack that allows an attacker to recover the internal states of the cryptosystem and to use them in order to encrypt or decrypt any image. Experimental results demonstrate the effectiveness of the attack and the lack of diffusion of the cryptosystem. Finally, a solution is proposed that can increment the security of the cryptosystem and render the cryptanalysis ineffective.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128461091","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, these documents do not provide much guidance about recognizing potential problems or about preventative measures. Even so, it is apparent that knowingly tolerating dishonesty or incompetence within the corporation is likely to be regarded as negligence. Most organizations today pay little attention to the inter-relationship between the Formal component, Technical component and Informal component. The Board and senior management of organizations tend to focus more on narrow aspects such as IS/IT management rather than on a comprehensive view. Deficiencies in any of these three components may result in unbalanced IS/IT security implementation. The objective of this study is to integrate the three components simultaneously throughout the IS/IT security implementation. The model of IS/IT security governance is a comprehensive conceptual framework because it emphasizes the two-way relationship between each of the components. In this study, a triangulated approach is adopted, data were collected in three phases, phase 1 is a website analysis, phase 2 is an interview and phase 3 is a mail survey. The interactions of three components, formal, technical and informal are significant in the IS/IT security governance model.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129623461","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}

This has to ensure not only the confidentiality and integrity of the data, but also to allow the definition of security policies which reflect the need for privacy of the health care organization that manages the data; of the patient, who the documents refer to; and finally of international and national directives and norms. In literature there are several access control models, each of which responds just partially to the need for patient privacy. In this paper an innovative access control model is defined. It meets the main features that have to be satisfied by an EHR. Our proposal is an advanced access control model that combines several access control models known in the literature. It adds the characteristics of modularity and easiness in the management of access policies, focusing attention on privacy and patient's consent (patient privacy centric). The model provides the ability to define and to realize fine-grained access policies, which can be defined independently by both healthcare organizations and by patients. Our model is Attribute-based, multi-level, modular and with a dynamic and temporal management of the users' lists.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983257","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, all existing schemes exhibit one or more drawbacks that prevent them from achieving the optimal performance in practice. For example, some schemes under-utilize the available bandwidth; some schemes enforce high overhead logic; and some schemes have rigid policies and parameters that do not adapt to ever-changing system runtime and network conditions. In this paper, we propose RUFC, an efficient and flexible framework to support Reliable UDP with Flow Control. Our framework fits between the transport layer employing UDP and the application layer. While providing the common functionalities and interfaces for both layers, RUFC is capable of supporting policy customization and parameter tuning to achieve the optimal application performance. Extensive experimental data shows that RUFC significantly outperforms the native UDP protocol as well as the two state-of-the-art UDP-based protocols (UDT and Tsunami) in terms of throughput and error rate.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114542276","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}

Although there have been some research projects which aim at extraction of discussion processes, these existing methods have not consider the diversity of description granularity. This research has aimed to develop a support system for extracting discussion processes and their visualization.

Typically such schemes are not resilient to shoulder surfing attacks, that is, if the adversary can observe (and “understand”) a number of authentication sessions, he can identify the secret password. In this paper we propose a new paradigm for user authentication. FilmPW is a graphical authentication system where the system challenges the user by showing her a short film containing a number of pre-defined pass-events and the user has reply by proving she recognized such events. We present FilmPW, discuss some issues related to event classification and present a prototye implementation. Our preliminary experiments show that such an authentication mechanism is highly accepted by users and achieves low error rates.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"370 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133082372","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}

For this reason, medical centers spend a lot of money to improve their information security. One of the methods of improving medical information security is encryption of medical information that can be implemented with various algorithms. Due to the special characteristics of visual data and other information, methods used in image cryptography are limited and in some cases, they suffer from some security flaws and limitations in application. In this paper, according to the chaotic characteristics of cellular automata, new algorithm has been proposed for encryption medical image. The results indicated that the proposed algorithm provided more security as well as higher speed. Moreover, this method hasn't any errors in decryption stage. These features are rarely seen simultaneously in one encryption algorithm.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"319 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133365531","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}

After that many public key cryptographic algorithms have been proposed based on single mathematical problem. Enhancing security is the major objective for public key cryptosystem on the basis of hardness of the intractable computational problem. To enhance security a new public key encryption scheme is designed based on two hard problems namely expressing a torsion point into linear combination of basis points and factoring. Since former is more complicate than solving ECDLP. So our proposed scheme is more secure than cryptosystems based on ECDLP and factoring. Therefore, this scheme is expected to gain a higher level of security. Developed scheme is more efficient with respect to encryption and decryption since it requires only minimal operations in both algorithms.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123320502","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}
