Encryption protects information stored on smartphones, laptops, and other devices - in some cases by default. Encrypted communications are provided by widely used computing devices and services - such as smartphones, laptops, and messaging applications - that are used by hundreds of millions of users. Individuals, organizations, and governments rely on encryption to counter threats from a wide range of actors, including unsophisticated and sophisticated criminals, foreign intelligence agencies, and repressive governments. Encryption on its own does not solve the challenge of providing effective security for data and systems, but it is an important tool. At the same time, encryption is relied on by criminals to avoid investigation and prosecution, including criminals who may unknowingly benefit from default settings as well as those who deliberately use encryption. Thus, encryption complicates law enforcement and intelligence investigations. When communications are encrypted "end-to-end," intercepted messages cannot be understood. When a smartphone is locked and encrypted, the contents cannot be read if the phone is seized by investigators. Decrypting the Encryption Debate reviews how encryption is used, including its applications to cybersecurity; its role in protecting privacy and civil liberties; the needs of law enforcement and the intelligence community for information; technical and policy options for accessing plaintext; and the international landscape. This book describes the context in which decisions about providing authorized government agencies access to the plaintext version of encrypted information would be made and identifies and characterizes possible mechanisms and alternative means of obtaining information.

Opera accademica completa con l'obiettivo di verificare la sicurezza delle reti WiFi, in modo teorico e pratico, ricercando con approccio sperimentale i possibili metodi per decifrare la password ed i relativi rischi da accesso non autorizzato. Nella prima parte del testo, al fine di definire le linee guida per una corretta implementazione della rete, si esaminano le caratteristiche generali di funzionamento delle reti WiFi stabilite dal protocollo IEEE 802.11, con particolare riguardo allo strato fisico ed allo strato collegamento della pila protocollare. Successivamente si considera l'aspetto sicurezza descrivendo le metodologie di autenticazione ed accesso alla rete, i rischi potenziali di attacchi alla sicurezza e la legislatura vigente in materia di violazione delle reti. Quindi si procede alla realizzazione di una rete WiFi di test ed alla simulazione dei possibili attacchi alla sicurezza dimostrando con esempi pratici, la cattura del traffico, la rilevazione della password e del contenuto informativo in chiaro. Si utilizzano strumenti come "Kali Linux", "Aircrack", "Virtualbox" e antenne compatibili con il "Monitor Mode". Nella seconda parte si analizza il procedimento di decifratura dei sistemi di protezione WiFi attualmente più sicuri, il WPA ed il WPA2, utilizzando l'analizzatore di protocollo "Wireshark" per la cattura dei dati di autenticazione ed il linguaggio di programmazione "Python" per l'implementazione software. L'opera si conclude con il "Password Engineering", analizzando le metodologie e tecniche più comunemente utilizzate per la scelta di una password e l'applicativo professionale "Hashcat" per la decifratura.

In cryptography, ciphers is the technical term for encryption and decryption algorithms. They are an important sub-family that features high speed and easy implementation and are an essential part of wireless internet and mobile phones. Unlike block ciphers, stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step. Typically stream ciphers can reach higher speeds than block ciphers but they can be more vulnerable to attack. Here, mathematics comes into play. Number theory, algebra and statistics are the key to a better understanding of stream ciphers and essential for an informed decision on their safety. Since the theory is less developed, stream ciphers are often skipped in books on cryptography. This book fills this gap. It covers the mathematics of stream ciphers and its history, and also discusses many modern examples and their robustness against attacks. Part I covers linear feedback shift registers, non-linear combinations of LFSRs, algebraic attacks and irregular clocked shift registers. Part II studies some special ciphers including the security of mobile phones, RC4 and related ciphers, the eStream project and the blum-blum-shub generator and related ciphers. Stream Ciphers requires basic knowledge of algebra and linear algebra, combinatorics and probability theory and programming. Appendices in Part III help the reader with the more complicated subjects and provides the mathematical background needed. It covers, for example, complexity, number theory, finite fields, statistics, combinatorics. Stream Ciphers concludes with exercises and solutions and is directed towards advanced undergraduate and graduate students in mathematics and computer science.

The latest edition of "Decoding the Chinese Internet: A Glossary of Political Slang" introduces classic memes created by Chinese netizens to counter censorship. We have added 17 new terms in an improved, image-rich format. China Digital Times maintains a wiki of subversive Chinese Internet language, an essential element of China’s “resistance discourse” which counters state propaganda. This Grass-Mud Horse Lexicon is named after the unofficial mascot of Chinese netizenry, an alpaca whose name sounds nearly the same as a serious profanity. We have added hundreds of terms to the Lexicon, and in 2013 began to publish eBook glossaries of the most time-tested and ubiquitous terms. In this third edition of “Decoding the Chinese Internet,” we have added both new coinages and iconic turns of phrase. Organized by broad categories, “Decoding the Chinese Internet” guides readers through the raucous world of China’s online resistance discourse. Students of Mandarin will gain insight into word play and learn terms that are key to understanding Chinese Internet language. But no knowledge of Chinese is needed to appreciate the creative leaps netizens make in order to keep talking.
