As an example, Paterson pointed to discussions between those technical experts developing the standards for the domain name system DNS and those working on a new version for transport layer security TLS which hides website content traveling through the network. Websites fetched via https instead of http are protected with TLS. Advances in cryptography Yet Paterson reported some success in closing loopholes in crypto standards in post-Snowden times. Reiterated successful attacks by cryptographers including Paterson against Rivest Cipher 4 RC4 , a stream cipher suite used for TLS finally had resulted in big internet players finally moving away from it. By now use of the RC4 had not only dropped to 7 percent for TLS connections worldwide compared to still 50 percent in , one year after the publication of the attack. There is also a proposed standard document deprecating it as a standard. NIST, privacy and security expert Susan Landau noted, meanwhile has decided for a reform of its own processes to stem compromises. Privacy researcher and activist Chris Soghoian, from the American Civil Liberties Union ACLU , pointed to pressures from law enforcement agencies against companies to not deploy technologies that made communication more secure. Despite the trickling down of hacking technology from the rich spies to the poor local law enforcement level, it is local law enforcement which would go dark with technologies such as Signal for secure messaging on the Iphone or WhatsApp. And it is local law enforcement, Soghoian warned, that is calling for the backdoors in crypto, and the NSA providing for it. Crypto researchers in post-Snowden times also have to reconsider their work, Paterson pointed out quoting Phillip Rogaway, a cryptography professor at the University of California. Instead of trusting an application provider with one's list of buddies - a rather valuable piece of metadata, such lists could be kept locally and presence be established by enhanced private information retrieval PIR. The server side of the protocol is ready to be used, yet people are still to deploy from the client side, Ian Goldberg, Associate Professor at the University of Waterloo, explained. Adaptive padding was the way to go, according to Diaz. The option would add bits to the stream of packets to make it look like a generic traffic stream.

To begin this process of revision, the fourth edition was extensively reviewed by a number of professors who teach the subject. In addition, a number of professionals working in the field reviewed individual chapters. The result is that, in many places, the narrative has been clarified and tightened, and illustrations have been improved. One obvious change to the book is a revision in the organization, which makes for a clearer presentation of related topics. There is a new Part Three, which pulls together all of the material on cryptographic algorithms for data integrity, including cryptographic hash functions, message authentication codes, and digital signatures.

The material on key management and exchange, previously distributed in several places in the book, is now organized in a single chapter, as is the material on user authentication. Beyond these refinements to improve pedagogy and user friendliness, there have been major substantive changes throughout the book.

Highlights include: Euclidean and extended Euclidean algorithms revised : These algorithms are important for numerous cryptographic functions and algorithms. The material on the Euclidean and extended Euclidean algorithms for integers and for polynomials has been completely rewritten to provide a clearer and more systematic treatment.

Advanced Encryption Standard revised : AES has emerged as the dominant symmetric encryption algorithm, used in a wide variety of applications. Accordingly, this edition has dramatically expanded the resources for learning about and understanding this important standard.

The chapter on AES has been revised and expanded, with additional illustrations and a detailed example, to clarify the presentation.

Examples and assignments using Sage have been added. And the book now includes an AES cryptography lab, which enables the student to gain hands-on experience with AES cipher internals and modes of use. The lab makes use of an AES calculator applet, available at this book's Web site, that can encrypt or decrypt test data values using the AES block cipher.


Block Cipher Modes of Operation revised : The material in Chapter 6 on modes of operation has been expanded and the illustrations redrawn for greater clarity. Pseudorandom number generation and pseudorandom functions revised : The treatment of this important topic has been expanded, with the addition of new material on the use of symmetric encryption algorithms and cryptographic hash functions to construct pseudorandom functions.

ElGamal encryption and digital signature new : New sections have been added on this popular public-key algorithm.

Cryptographic hash functions and message authentication codes revised : The material on hash functions and MAC has been revised and reorganized to provide a clearer and more systematic treatment. SHA-3 new : Although the SHA-3 algorithm has yet to be selected, it is important for the student to have a grasp of the design criteria for this forthcoming cryptographic hash standard.

Authenticated encryption new : The book covers the important new algorithms, CCM and GCM, which simultaneously provide confidentiality and data integrity. Key management and distribution revised : In the fourth edition, these topics were scattered across three chapters.

In the fifth edition, the material is revised and consolidated into a single chapter to provide a unified, systematic treatment. Remote user authentication revised : In the fourth edition, this topic was covered in parts of two chapters. In the fifth edition the material is revised and consolidated into a single chapter to provide a unified, systematic treatment. Federated identity new : A new section covers this common identity management scheme across multiple enterprises and numerous applications and supporting many thousands, even millions, of users.

Secure shell new : SSH, one of the most pervasive applications of encryption technology, is covered in a new section. Wireless network security new : A new chapter covers this important area of network security. The chapter deals with the IEEE A cutting-edge technique for front-end security is the TPM trusted platform module , commonly known as the security chip.

In view of the running time, the encryption of long-length multimedia data, such as an image, is definitely outside the TPM. The other approach, back-end security, protects huge amounts of data because multimedia information, crucial for the interaction between ubiquitous devices and human beings, uses massive amounts of data.

Back-end security is usually covered by common key schemes.

Common key module-embedded processors are built-in cryptography processors for IC cards and portable electronic devices. On the other hand, considering that cipher algorithms are open to third parties in the evaluation of cipher strength, hardware specifications are more important than cipher strength in developing an ad hoc network infrastructure.

A fundamental issue in maintaining the mobility of the ubiquitous environment is how to achieve power-saving mobility. The power consuming factors of ubiquitous networks are large server systems controlled by network providers and small ubiquitous platform systems, handheld devices and so forth.

These small systems consist of processors, memory and displays. The power dissipation of memory strongly depends on that of a memory cell and the memory space required for embedded software. LCDs liquid crystal displays and processors consume similar power in running mobile devices. While the LCD is turned on only when it displays some information, processors are always in the standby state to receive calls.

Thus, power-saving restrictions for mobile devices are inevitably imposed on the processors. Another issue of ubiquitous computing is its strong dependency on embedded software. This has a crucial effect on the total design of ubiquitous devices.

Performable features of ubiquitous devices in processing multimedia data have mainly relied on embedded software. For example, if a new protocol appears, embedded software requires users to download an update package. Despite embedding, so far, it has rapidly increased software size due to the RTOS real time OS , firmware, application software and so on.

This results in more software costs and wider memory space.

Since cutting-edge ubiquitous devices need not only sophisticated and complicated processing, but also power conscious high-speed operation, the embedded software approaches taken so far will not always continue to play key roles in ubiquitous computing.

In order to solve the fundamental issues described above, power conscious management of ubiquitous networks and cryptographic protection of massive data spreading over ubiquitous networks are required. It is really the practice of cryptography network security technologies to show optimum design for the trade-off to achieve specific features of the ubiquitous network. The double cipher scheme presented in this paper combines two cipher algorithms [ 4 ].

One is random number addressing cryptography RAC , closely related to the internal behaviour of the processors.

RAC is a transposition cipher devised from the direct connection of a built-in random number generator RNG , a register file and a data cache. The register file plays the role of a streaming buffer. A random store, based on the direct connection, scrambles or transposes a series of multimedia data at random without any special encryption operation.

The other algorithm of the double cipher is a data sealing algorithm. This is implemented during the data transfer from the register file to the data cache, by using another built-in RNG.

Since the double cipher scheme uses built-in RNGs at the micro-operation level, it is more effective than normal usage based on the processing of random number operands at the instruction level.

In addition, the double cipher scheme requires no additional chip area or power dissipation. Thus, the double cipher scheme is a microarchitecture-based, software-transparent hardware cipher that offers security for the whole data with negligible hardware cost and moderate performance overhead.

This is very suited to very large scale integration VLSI implementation. The VLSI implementation of the double cipher follows the multicore structure for bi-directional communication and multiple pipelines for multimedia processing and cipher streaming [ 5 ].
