George Davida
George I. Davida is an American computer scientist and cryptographer. He is an outspoken proponent of public access to cryptography and an opponent of various National Security Agency (NSA) and US federal government policies and initiatives like the Clipper chip, a stance dating back to his 1977 reception of a gag order from the NSA under the Invention Secrecy Act relating to a patent application for a stream cipher device, using research funded by a National Science Foundation grant. He used to work at the Department of Electrical Engineering and Computer Science at the University of Iowa. He was director of the University of Wisconsin–Milwaukee The University of Wisconsin–Milwaukee (UW–Milwaukee, UWM, or Milwaukee) is a public urban research university in Milwaukee, Wisconsin. It is the largest university in the Milwaukee metropolitan area and a member of the University of Wiscons ...'s Center for Cryptography, Computer and Network Security, until retiring in 2010.

Computer Scientist
A computer scientist is a person who is trained in the academic study of computer science. Computer scientists typically work on the theoretical side of computation, as opposed to the hardware side on which computer engineers mainly focus (although there is overlap). Although computer scientists can also focus their work and research on specific areas (such as algorithm and data structure development and design, software engineering, information theory, database theory, computational complexity theory, numerical analysis, programming language theory, computer graphics, and computer vision), their foundation is the theoretical study of computing from which these other fields derive. A primary goal of computer scientists is to develop or validate models, often mathematical, to describe the properties of computational systems (processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discovering des ...

Stream Cipher
stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit is dependent on the current state of the cipher, it is also known as ''state cipher''. In practice, a digit is typically a bit and the combining operation is an exclusive-or (XOR). The pseudorandom keystream is typically generated serially from a random seed value using digital shift registers. The seed value serves as the cryptographic key for decrypting the ciphertext stream. Stream ciphers represent a different approach to symmetric encryption from block ciphers. Block ciphers operate on large blocks of digits with a fixed, unvarying transformation. This distinction is not always clear-cut: in some modes of operation, a block cipher primitive is used in such a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Wisconsin–Milwaukee Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in ...

Patent Application
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office. To obtain the grant of a patent, a person, either legal or natural, must file an application at a patent office with the jurisdiction to grant a patent in the geographic area over which coverage is required. This is often a national patent office, but may be a regional body, such as the European Patent Office. Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification. The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with a patent offic ...

Cryptographer
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention Secrecy Act
The Invention Secrecy Act of 1951 (, codified at ) is a body of United States federal law designed to prevent disclosure of new inventions and technologies that, in the opinion of selected federal agencies, present a possible threat to the national security of the United States. The U.S. government has long sought to control the release of new technologies that might threaten the national defense and economic stability of the country. During World War I, Congress authorized the United States Patent and Trademark Office (PTO) to classify certain defense-related patents. This initial effort lasted only for the duration of that war but was reimposed in October 1941 in anticipation of the U.S. entry into World War II. Patent secrecy orders were initially intended to remain effective for two years, beginning on July 1, 1940, but were later extended for the duration of the war (). The Invention Secrecy Act of 1951 made such patent secrecy permanent, though the order to suppress a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Puzzle Palace
''The Puzzle Palace'' is a book written by James Bamford and published in 1982. It is the first major, popular work devoted entirely to the history and workings of the National Security Agency (NSA), a United States intelligence organization. The title refers to a nickname for the NSA, which is headquartered in Fort Meade, Maryland. In addition to describing the role of the NSA and explaining how it was organized, the book exposed details of a massive eavesdropping operation called Operation Shamrock. According to security expert Bruce Schneier, the book was popular within the NSA itself, as "the agency's secrecy prevents its employees from knowing much about their own history". Research and publication The NSA describes Bamford's research process in a partially declassified history of postwar American cryptography. The history begins by describing how Bamford approached Houghton-Mifflin with a proposal to write a book on the NSA. The publisher accepted and paid Bamford a $7,50 ...
