Daniel J. Bernstein
Daniel Julius Bernstein (born October 29, 1971) is an American mathematician, cryptologist, and computer scientist. He was a professor of Computer Science at the University of Illinois at Chicago from 1995 to 2008. He was a visiting professor in the department of mathematics and computer science at the Eindhoven University of Technology, and a visiting professor at CASA at Ruhr University Bochum through 2023. Early life Bernstein attended Bellport High School, a public high school on Long Island, graduating in 1987 at the age of 15. The same year, he ranked fifth in the Westinghouse Science Talent Search. In 1987, he achieved a Top 10 ranking in the William Lowell Putnam Mathematical Competition, and was a member of the second-place team from Princeton University the following year. Bernstein earned a B.A. in mathematics from New York University (1991) and a Ph.D. in mathematics from the University of California, Berkeley (1995), where he studied under Hendrik Lenstra.

East Patchogue, New York
East Patchogue (, ) is a hamlet and census-designated place (CDP) in the Town of Brookhaven in Suffolk County, on the South Shore of Long Island, in New York, United States. The population was 21,580 at the time of the 2020 census. The CDP is a proximate representation of the East Patchogue hamlet used for statistical purposes of the United States Census Bureau. History Patchogue has historically been a major shopping and commerce hub of Suffolk County. "Patchogue" in the narrow sense is an incorporated village with narrow limits, only about a mile and a half wide. East Patchogue includes the eastern portion of Patchogue in the wider sense, as well as the area east of that but still west of the incorporated village of Bellport. This double meaning of "East Patchogue" is reflected in the naming of New York State Route 27A: It is called "East Main Street" in the western portion of East Patchogue, and "Montauk Highway" (as it typically is outside of villages) in the eastern ...

Curve25519
In cryptography, Curve25519 is an elliptic curve used in elliptic-curve cryptography (ECC) offering 128 bits of security (256-bit key size) and designed for use with the Elliptic-curve Diffie–Hellman (ECDH) key agreement scheme, first described and implemented by Daniel J. Bernstein. It is one of the fastest curves in ECC, and is not covered by any known patents. The reference implementation is public domain software. The original Curve25519 paper defined it as a Diffie–Hellman (DH) function. Bernstein has since proposed that the name Curve25519 be used for the underlying curve, and the name X25519 for the DH function. Mathematical properties The curve used is y^2 = x^3 + 486662x^2 + x, a Montgomery curve, over the prime field defined by the pseudo-Mersenne prime number 2^ - 19 (hence the numeric "" in the name), and it uses the base point x = 9. This point generates a cyclic subgroup whose order is the prime 2^ + 27742317777372353535851937790883648493. This subgroup has ...

Munition
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected Targeting (warfare), target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm Cartridge (firearms), cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Export Of Cryptography From The United States
The export of cryptography from the United States to other countries has experienced various levels of restrictions over time. World War II illustrated that code-breaking and cryptography can play an integral part in national security and the ability to prosecute war. Changes in technology and the preservation of free speech have been competing factors in the regulation and constraint of cryptographic technologies for export. History Cold War era In the early days of the Cold War, the U.S. and its allies developed an elaborate series of export control regulations designed to prevent a wide range of Western technology from falling into the hands of others, particularly the Eastern bloc. All export of technology classed as 'critical' required a license. CoCom was organized to coordinate Western export controls. Two types of technology were protected: technology associated only with weapons of war ("munitions") and dual use technology, which also had commercial applications. In t ...

Visiting Professor
In academia, a visiting scholar, visiting scientist, visiting researcher, visiting fellow, visiting lecturer, or visiting professor is a scholar from an institution who visits a host university to teach, lecture, or perform research on a topic for which the visitor is valued. In many cases, the position is not salaried because the visitor is salaried by their home institution (or partially salaried, as in some cases of sabbatical leave from US universities). Some visiting positions are salaried. Typically, a visiting scholar may stay for a couple of months or even a year,UT"Visiting Scholar". The University of Texas at Austin. though the stay can be extended. A visiting scholar is usually invited by the host institution, and it is not out of the ordinary for them to provide accommodation. Such an invitation is often regarded as recognizing the scholar's prominence in the field. Attracting prominent visiting scholars often allows the permanent faculty and graduate students t ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other tertiary education, post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a 'person who professes'. Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word ''professor'' is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well, and often to instructors or lecturers.
