Book Description
Cloud computing is a technology or distributed network where user can move their data and any application software on it. With the use of this technology user need not to worry about the cost of hardware installation and their maintenance cost. Cloud computing provide different services to user. Cloud computing is now become most popular technology because of its availability, low cost and some other factors. But there is some issues in cloud computing, the main one is security because every user store their useful data on the network so they want their data should be protected from any unauthorized access, any changes that is not done on user's behalf. There are different encryption techniques used for security purpose like FDE and FHE. FDE encrypts the entire disk and FHE encrypts the particular functions. In representative architecture we use the term FHE for encryption. To solve the problem of Key management, Key Sharing various schemes have been proposed. The third party auditor is the scheme for key management and key sharing. The main advantage of this is the cloud service provider can offer the functions which were provided by the traditional third party auditor and make it trustful. The third party auditing scheme will be failed, if the third party's security is compromised or of the third party will be malicious. To solve this problem, we will work on to design new modal for key sharing and key management in fully Homomorphic Encryption scheme. In this we use the symmetric key agreement algorithm named Diffie Hellman, it is key exchange algorithm with create session key between two parties who want to communicate with each other and HMAC for the data integrity OTP(One Time Password) is created which provides more security. Due to this the problem of managing the key is removed and data is more secured.

Book Description
This book explores the latest developments in fully homomorphic encryption (FHE), an effective means of performing arbitrary operations on encrypted data before storing it in the ‘cloud’. The book begins by addressing perennial problems like sorting and searching through FHE data, followed by a detailed discussion of the basic components of any algorithm and adapting them to handle FHE data. In turn, the book focuses on algorithms in both non-recursive and recursive versions and discusses their realizations and challenges while operating in the FHE domain on existing unencrypted processors. It highlights potential complications and proposes solutions for encrypted database design with complex queries, including the basic design details of an encrypted processor architecture to support FHE operations in real-world applications.

Book Description
With the development of the cloud computing, recently, many service models have appeared which are based on the cloud computing, such as infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and database as a service (DaaS). For DaaS, there exist many security issues. Especially, the database as a service cannot be fully secured because of some security problems. This research area of cloud computing is called as cloud security. One of the problems is that it is difficult to execute queries on encrypted data in cloud database without any information leakage. This thesis proposes a secure range query process which is based on a somewhat homomorphic encryption scheme to improve secure database functionalities. There is no sensitive information leakage in the secure range query process. The data that are stored in the cloud database are the integers which are encrypted with their binary forms by bits. A homomorphic "greater-than" algorithm is used in the process to compare two integers. Efficiency, security, and the maximum noise that can be controlled in the process are covered in the security and efficiency analysis. Parameter setting analysis of the process will also be discussed. Results of the proposed method have been analyzed through some experiments to test the secure range query process for its practicability with some relatively practical parameter settings.
