Abstract
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.
Highlights
The security issues are very important for business flow, especially, while using the financial data and business e-commerce models
The results of the hash codes are recollected by the executive operations (XOR gate) to generate the final Hash of the Encrypted Block Object (EBO) (HEBOs). This hash value HEBOs is encrypted by using the RSA algorithm with the private key of DWServer to generate the Encrypted Hash of the EBOs (EHEBOs)
This model compares between the two hash codes, the hash code of HEBOs sent from DWServer with the hash code of HEBOs computed in the Client side
Summary
The security issues are very important for business flow, especially, while using the financial data and business e-commerce models. The potential increase of internet users and multiple types of network technologies open ways for researchers to develop multiple types of middleware. This increase leads to the increase of data storages that are connected together for query of many business organizations. The security issues contain three attributes of data which are Confidentiality, Integrity and Availability called (CIA) [1,2]. The data availability uses the middleware techniques as a cluster or grid in parallel computing to reach high performance.
