Encrypted Database

Cloud computing gives out the ability that sells computing, storage and other IT resource as service instead of sells hardware. There are also some problems that block the advancement. This paper discussed these problem, especially in database-as-a-service then introduced a mean-tree structure, that extends the encrypted database’s ability, trying to surpass the existence conclusion that an encrypted database is inefficient.

Multi Cloud

The need for data outsourcing or database as a service (DaaS) is extremely important for any organization. In addition, data storage or data retrieval cost high especially for small companies. This chapter aims to study the various challenges in cloud computing communication issue. The chapter on multi-tiering a cloud emphasizes security enhancement due to the application of tiers in the cloud such that services availability is also improved. Cloud computing is a recent network trend for advanced communication systems. A lot of research led to the advancements in the areas of newer modes but multi-tiering a cloud is still an embarking issue for the researchers.

Order Comparison

With the advance of database-as-a-service (DaaS) and cloud computing, increasingly more data owners are motivated to outsource their data to cloud database for great convenience and economic savings. Many encryption schemes have been proposed to process SQL queries over encrypted data in the database. In order to obtain the desired data, the SQL queries contain some statements to describe the requirement, e.g., arithmetic and comparison operators (+, -, ×, <, >, and =). However, to support different operators (+, -, ×, <, >, and =) in SQL queries over encrypted data, multiple encryption schemes need to be combined and adjusted to work together. Moreover, repeated encryptions will reduce the efficiency of execution. This paper presents a practical and secure homomorphic order-preserving encryption (FHOPE) scheme, which allows cloud server to perform complex SQL queries that contain different operators (such as addition, multiplication, order comparison, and equality checks) over encrypted data without repeated encryption. These operators are data interoperable, so they can be combined to formulate complex SQL queries. We conduct security analysis and efficiency evaluation of the proposed scheme FHOPE. The experiment results show that, compared with the existing approaches, the FHOPE scheme incurs less overhead on computation and communication. It is suitable for large batch complex SQL queries over encrypted data in cloud environment.

<span>Cloud Computing is an environment where computing resources, such as processing power, storage, network, application, and other IT services, are provided to users as computing utility. This paper presents the university distributed databases consolidation and relocation to the cloud for the provision of Database as a Service (DBaaS), through their deployment into high availability, interactive, secure private cloud setup utilizing Al-Balqa Applied University (BAU) Private Cloud (BPC). This solution involves several transitions, and represents the main key step in BAU journey to the cloud to allow the university to achieve greater efficiency in terms of database services, and to improve performance, availability, interactivity, and security. The resulted service also reduces operating, management and capital costs.</span>
