NSA's Efforts to Secure Private-Sector Telecommunications Infrastructure
Under the Radar: NSA’s Efforts to Secure Private-Sector Telecommunications Infrastructure Susan Landau* INTRODUCTION When Google discovered that intruders were accessing certain Gmail ac- counts and stealing intellectual property,1 the company turned to the National Security Agency (NSA) for help in securing its systems. For a company that had faced accusations of violating user privacy, to ask for help from the agency that had been wiretapping Americans without warrants appeared decidedly odd, and Google came under a great deal of criticism. Google had approached a number of federal agencies for help on its problem; press reports focused on the company’s approach to the NSA. Google’s was the sensible approach. Not only was NSA the sole government agency with the necessary expertise to aid the company after its systems had been exploited, it was also the right agency to be doing so. That seems especially ironic in light of the recent revelations by Edward Snowden over the extent of NSA surveillance, including, apparently, Google inter-data-center communications.2 The NSA has always had two functions: the well-known one of signals intelligence, known in the trade as SIGINT, and the lesser known one of communications security or COMSEC. The former became the subject of novels, histories of the agency, and legend. The latter has garnered much less attention. One example of the myriad one could pick is David Kahn’s seminal book on cryptography, The Codebreakers: The Comprehensive History of Secret Communication from Ancient Times to the Internet.3 It devotes fifty pages to NSA and SIGINT and only ten pages to NSA and COMSEC. -

Cryptography
Cryptography From Wikipedia, the free encyclopedia Jump to: navigation, search "Secret code" redirects here. For the Aya Kamiki album, see Secret Code. German Lorenz cipher machine, used in World War II to encrypt very-high-level general staff messages Cryptography (or cryptology; from Greek κρυπτός, kryptos, "hidden, secret"; and γράφ, gráph, "writing", or -λογία, -logia, respectively)[1] is the practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Cryptology prior to the modern age was almost synonymous with encryption, the conversion of information from a readable state to nonsense. The sender retained the ability to decrypt the information and therefore avoid unwanted persons being able to read it. Since WWI and the advent of the computer, the methods used to carry out cryptology have become increasingly complex and its application more widespread. Alongside the advancement in cryptology-related technology, the practice has raised a number of legal issues, some of which remain unresolved.

An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext
An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext By Isaac Quinn DuPont A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Faculty of Information University of Toronto © Copyright by Isaac Quinn DuPont 2017 ii An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext Isaac Quinn DuPont Doctor of Philosophy Faculty of Information University of Toronto 2017 Abstract Tis dissertation is an archeological study of cryptography. It questions the validity of thinking about cryptography in familiar, instrumentalist terms, and instead reveals the ways that cryptography can been understood as writing, media, and computation. In this dissertation, I ofer a critique of the prevailing views of cryptography by tracing a number of long overlooked themes in its history, including the development of artifcial languages, machine translation, media, code, notation, silence, and order. Using an archeological method, I detail historical conditions of possibility and the technical a priori of cryptography. Te conditions of possibility are explored in three parts, where I rhetorically rewrite the conventional terms of art, namely, plaintext, encryption, and ciphertext. I argue that plaintext has historically been understood as kind of inscription or form of writing, and has been associated with the development of artifcial languages, and used to analyze and investigate the natural world. I argue that the technical a priori of plaintext, encryption, and ciphertext is constitutive of the syntactic iii and semantic properties detailed in Nelson Goodman’s theory of notation, as described in his Languages of Art. I argue that encryption (and its reverse, decryption) are deterministic modes of transcription, which have historically been thought of as the medium between plaintext and ciphertext. -
The Export of Cryptography in the 20 Century and the 21
The Export of Cryptography th st in the 20 Century and the 21 ∗ Whitfield Diffie and Susan Landau Sun Microsystems, Inc Palo Alto CA April 19, 2005 August 2000 On the 14th of January 2000, the Bureau of Export Administration issued long-awaited revisions to the rules on exporting cryptographic hardware and software. The new regulations, which grew out of a protracted tug of war between the computer industry and the U.S. Government, are seen by indus- try as a victory. Their appearance, which was attended by both excitement and relief, marked a substantial change in export policy. This paper exam- ines the evolution of export control in the cryptographic area and considers its impact on the deployment of privacy-protecting technologies within the United States. Before the electronic age, all \real-time" interaction between people had to take place in person. Privacy in such interactions could be taken for granted. No more than reasonable care was required to assure yourself that only the people you were addressing | people who had to be right there with you | could hear you. Telecommunications have changed this. The people with whom you interact no longer have to be in your immediate vicinity; they can be on the other side of the world, making what was once impossible spontaneous and inexpensive. Telecommunication, on the other hand, makes protecting yourself from eavesdropping more difficult. Some other security mechanism is required to replace looking around to see that ∗To appear in the Handbook of the History of Information Security Elsevier B.V. 1 no one is close enough to overhear: that mechanism is cryptography, the only security mechanism that directly protects information passing out of the physical control of the sender and receiver. -

COMPLAINT 1. Plaintiff Democracy Forward Foundation (“Democracy Forward”) brings this action against Defendant the U.S. Agency for Global Media (“USAGM”) to compel compliance with the Freedom of Information Act, 5 U.S.C. § 552 (“FOIA”). 2. On November 15, 2018, Democracy Forward submitted a FOIA request to USAGM (“First Request”) seeking records relating to a 15-minute video segment critical of George Soros (“Soros Segment”) that was televised in May 2018 by Radio and Television Martí—the primary outlet of the Office of Cuba Broadcasting, a component of USAGM. The Soros Segment has been widely decried as anti-Semitic. 3. On December 17, 2018, in response to media reports documenting widespread bias and inappropriate political influence at USAGM, Democracy Forward submitted another FOIA request (“Second Request”) seeking additional records relating to the Soros Segment, USAGM’s response to publication of the Soros Segment, and to an apparent broader trend of Case 1:19-cv-00608 Document 1 Filed 03/05/19 Page 2 of 11 USAGM affiliate offices breaching various journalistic norms, including by publishing bigoted and biased content. 4. Through these records requests, Democracy Forward seeks to shed light on how bigoted and biased content, like the Soros Segment, made it to air, and to understand both the steps taken in response and the personnel changes that are reportedly underway at USAGM and its affiliates. -

Johansson (Lund University) 3 / 17 Introduction to Cryptography Much of the theoretical work in cryptography concerns cryptographic primitives, algorithms with basic cryptographic properties. A cryptographic protocol involve back and forth communication among two or more parties. Symmetric-key cryptography – methods in which both the sender and receiver share the same key (block ciphers, stream ciphers, MAC algorithms). Cryptographic hash functions are a related and important class of cryptographic algorithms. Public-key cryptography – two different but mathematically related keys are used a public key and a private key. T. Johansson (Lund University) 4 / 17 History of cryptography Before the modern era, cryptography was concerned solely with message confidentiality (i.e., encryption) Encryption was used to (attempt) to ensure secrecy for spies, military, and diplomats.

LEGISLATIVE REFORM COMMENTARIES A Tyrant's Toolbox: Technology and Privacy in America The Honorable Bob Barr* I. Introduction By its nature, the law is typically a reactive force. It responds to breaches of soci- ety's moral code, by outlawing acts that individuals commit that take away those things society values - life, property, the fruits of one's labor. As American society grew and became more complex, federal law reacted with concurrent development. Robber barons acquired monopolies and Congress passed anti-trust laws. Prohibition-era organized crime syndicates began using military weapons on the street and Congress acted to out- law civilian ownership of such weapons. Drug dealers organized themselves into verti- cally-integrated distribution networks, and our government enacted laws against money laundering and continuing criminal enterprises. The list is long, and includes the numer- ous court decisions that have applied statutes to fact situations that were unimaginable earlier in our history or even when the laws were passed. -
