DecenCrypto Cloud: Decentralized Cryptography Technique for Secure Communication over the Clouds Shyam Nandan Kumar Journal of Computer Sciences and Applications. 2015 3 (3). doi: 10.12691/jcsa-3-3-3 Keywords: cloud computing, data sharing, Encryption , decryption, cloud security, cryptography, secure communication, data security, www Context: With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the Cloud, share a large amount of data day by day. Secure Data sharing is an important issue over the cloud environment. In order to enhance the security services, the paper proposes Decentralized Cryptography Technique for Secure Communication over the Clouds. In this paper, Cryptography Model for Secure Data Sharing over Cloud is presented first. Cryptography Management Approach is given to access the secure resource over cloud and then Algorithm Design Methodology is provided in decentralized manner. The paper also provides a concise but all-round analysis on data security and privacy protection issues associated with cloud computing. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Cryptography during Data Sharing and Accessing Over Cloud Shyam Nandan Kumar International Transaction of Electrical and Computer Engineers System. 2015 3 (1). doi: 10.12691/iteces-3-1-2 Keywords: cloud computing, data sharing, decryption, Encryption Context: Data sharing is an important functionality in cloud environment. With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the world generate a large amount of data daily. This data would be more useful to cooperating organizations if they were able to share their data. In this article, an efficient methodology is provided to securely, efficiently, and flexibly share data with others in cloud computing. In this technique, the secret key holder can release a constant-size aggregate key for flexible choices of cipher-text set in cloud storage, but the other encrypted files outside the set remain confidential. Secure cryptographic architecture and working methodology are proposed in this paper for optimal services over the cloud. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Data Warehouse Signature: A Framework for Implementing Security Issues in Data Warehouses Mayada J. AlMeghari Journal of Computer Sciences and Applications. 2017 5 (1). doi: 10.12691/jcsa-5-1-3 Keywords: security issues, data warehouse, data Encryption , data integrity, data availability, hash function, middleware Context: Today, with the increase in the number of business web application users, the data size is obviously getting quiet huge. This data is composed together from integrated heterogeneous data sources to form Data Warehouse (DW). DW consists of critical and sensitive data used in many intelligent business models for decision support processes. Therefore, retaining data security for DW systems is a very important issue for researchers; also, it is the first priority for organizations. The current paper presents a new framework for implementing security issues in DWs named Data Warehouse Signature (DWS). The DWS framework ensures the security issues, which are Confidentiality, Integrity and Availability (CIA). In fact, this approach solves the security problems such as network overhead and data changing that occurs during transmission on Client-Server basis. The DWS approach achieves high performance by using parallel computing through a middleware named View Manager Layer (VML). Finally, this paper also presents the elastic architecture of the DWS framework with a vast applicability in multiple DW organizations depending on its network infrastructure.

Review on Network Security and Cryptography Shyam Nandan Kumar International Transaction of Electrical and Computer Engineers System. 2015 3 (1). doi: 10.12691/iteces-3-1-1 Keywords: network security, cryptography, decryption, Encryption Context: With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the world generate a large amount of data daily. Data security is the utmost critical issue in ensuring safe transmission of information through the internet. Also network security issues are now becoming important as society is moving towards digital information age. As more and more users connect to the internet it attracts a lot of cyber-criminals. It comprises authorization of access to information in a network, controlled by the network administrator. The task of network security not only requires ensuring the security of end systems but of the entire network. In this paper, an attempt has been made to review the various Network Security and Cryptographic concepts. This paper discusses the state of the art for a broad range of cryptographic algorithms that are used in networking applications. Abstract Full Text (PDF) [Epub] Full Text (HTML)
