摘要：Data Warehouses are the most vital asset of an organization which contains sensitive information and data of an organization which is extracted from heterogeneous sources which is used in decision making process. A data warehouse by its nature, creates a security conflict on the other hand, the goal of every data warehouse is to make data accessible. Unfortunately, this also makes them an appearing target for malicious inside and outside attackers. Therefore, security is an important concern which should be defined in order to protect this sensitive information from unauthorized users to ensure integrity and confidentiality. Security should be considered from early stages of designing the data warehouse and hence should be deployed. Encryption is one security technique applied on data to cut out any unauthorized access for maintaining its integrity and delivery performance. In order, to meet these rigorous security challenges posed by protecting different types of information, a new encryption technique is defined known as Format Preserving Encryption mechanism wherein, the encrypted data fits into the existing schema and hence, changes to the database schema and underlying applications would not be required. In this paper, we introduce Format Preserving Encryption (FPE) technique with Advanced Encryption Standard (AES) to encrypt the data before keeping in data warehouse for improving the implementation of security of data warehouse
