Book excerpt: Professor Tikaya Komitopis isn't a great beauty, a fearless warrior, or even someone who can walk and chew chicle at the same time, but her cryptography skills earn her wartime notoriety. When enemy marines show up at her family's plantation, she expects the worst.But they're not there to kill her. They need her to decode mysterious runes, and they ask for help in the manner typical of a conquering empire: they kidnap her, threaten her family, and throw her in the brig of their fastest steamship.Her only ally is a fellow prisoner who charms her with a passion for academics as great as her own. Together, they must decipher mind-altering alchemical artifacts, deadly poison rockets, and malevolent technological constructs, all while dodging assassination attempts from a rival power determined the expedition should fail. As if the situation weren't treacherous enough, this new “ally” may turn out to be the last person Tikaya should trust. Those runes cloak more than mysteries, however, and he's the only one who can help her unravel them before their secrets destroy the world.

Book excerpt: This book comprehensively reviews searchable encryption, which represents a series of research developments that directly enable search functionality over encrypted data. The book majorly covers: 1) the design and implementation of encrypted search algorithms, data structures, and systems that facilitate various forms of search over always-encrypted databases; 2) different threat models, assumptions, and the related security guarantees, when using searchable encryption in the real-world settings; and 3) latest efforts in building full-fledged encrypted database systems that draw insights from searchable encryption constructions. The book fits in the timely context, where the necessity of safeguarding important and sensitive data has been globally recognized. Traditional security measures, such as storing data behind network firewalls and layers of access control mechanisms to keep attackers out, are no longer sufficient to cope with the expanding landscape of surging cyber threats. There is an urgent call to keep sensitive data always encrypted to protect the data at rest, in transit, and in use. Doing so guarantees data confidentiality for owners, even if the data is out of their hands, e.g., hosted at in-the-cloud databases. The daunting challenge is how to perform computation over encrypted data. As we unfold in this book, searchable encryption, as a specific line of research in this broadly defined area, has received tremendous advancements over the past decades. This book is majorly oriented toward senior undergraduates, graduate students, and researchers, who want to work in the field and need extensive coverage of encrypted database research. It also targets security practitioners who want to make well-informed deployment choices of the latest advancements in searchable encryption for their targeted applications. Hopefully, this book will be beneficial in both regards.

Download or read book Hybrid Encryption Algorithms over Wireless Communication Channels written by Mai Helmy Shaheen and published by CRC Press. This book was released on 2021-03-04 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel hybrid encryption algorithms that possess many different characteristics. In particular, “Hybrid Encryption Algorithms over Wireless Communication Channels”, examines encrypted image and video data for the purpose of secure wireless communications. A study of two different families of encryption schemes are introduced: namely, permutation-based and diffusion-based schemes. The objective of the book is to help the reader selecting the best suited scheme for the transmission of encrypted images and videos over wireless communications channels, with the aid of encryption and decryption quality metrics. This is achieved by applying number-theory based encryption algorithms, such as chaotic theory with different modes of operations, the Advanced Encryption Standard (AES), and the RC6 in a pre-processing step in order to achieve the required permutation and diffusion. The Rubik’s cube is used afterwards in order to maximize the number of permutations. Transmission of images and videos is vital in today’s communications systems. Hence, an effective encryption and modulation schemes are a must. The author adopts Orthogonal Frequency Division Multiplexing (OFDM), as the multicarrier transmission choice for wideband communications. For completeness, the author addresses the sensitivity of the encrypted data to the wireless channel impairments, and the effect of channel equalization on the received images and videos quality. Complete simulation experiments with MATLAB® codes are included. The book will help the reader obtain the required understanding for selecting the suitable encryption method that best fulfills the application requirements.

Download or read book Attribute level encryption of data in public Android databases written by Charles E. Loftis and published by RTI Press. This book was released on 2013-09-24 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Android mobile devices have become an attractive consumer product because of their portability, high-definition screens, long battery life, intuitive user interface, and ubiquitous competitive vendor pricing. The very feature that has helped with the proliferation of the devices is also one of the most problematic: their portability could result in theft, potentially allowing data to be compromised. For applications deployed to these devices, data security requirements need to be incorporated in the design process so these devices can be considered viable data collection tools. Researchers at RTI have been working to secure data on Android mobile devices so that selected information on the device can be encrypted and therefore difficult to obtain illegitimately while still making confidential data easy to access. We have developed software that will encrypt specific attributes of databases residing on the internal secure digital card (SD card) of Android devices. The method we have developed could also benefit other Android applications requiring secure storage of data on globally readable and writable databases. In this occasional paper, we discuss the technologies and methods used in our Android database encryption/ decryption implementation and their potential scalability to broader applications.

Download or read book Advances to Homomorphic and Searchable Encryption written by Stefania Loredana Nita and published by Springer Nature. This book was released on 2023-10-28 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the current state of the literature on the fields of homomorphic and searchable encryption, from both theoretical and practical points of view. Homomorphic and searchable encryption are still relatively novel and rapidly evolving areas and face practical constraints in the contexts of large-scale cloud computing and big data. Both encryption methods can be quantum-resistant if they use the right mathematical techniques. In fact, many fully homomorphic encryption schemes already use quantum-resistant techniques, such as lattices or characteristics of polynomials – which is what motivated the authors to present them in detail. On the one hand, the book highlights the characteristics of each type of encryption, including methods, security elements, security requirements, and the main types of attacks that can occur. On the other, it includes practical cases and addresses aspects like performance, limitations, etc. As cloud computing and big data already represent the future in terms of storing, managing, analyzing, and processing data, these processes need to be made as secure as possible, and homomorphic and searchable encryption hold huge potential to secure both the data involved and the processes through which it passes. This book is intended for graduates, professionals and researchers alike. Homomorphic and searchable encryption involve advanced mathematical techniques; accordingly, readers should have a basic background in number theory, abstract algebra, lattice theory, and polynomial algebra.
