The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, a pair of private and public keys are created: data encrypted with either key can ...
A digital signature is an authentication mechanism that enables the creator of the message to attach a code that acts as a signature. The Digital Signature Algorithm (DSA), developed by the National Institute of Standards and Technology, is one of many examples of a signing algorithm. In the following discussion, 1 n refers to a unary number.
A domain-specific architecture (DSA) is a programmable computer architecture specifically tailored to operate very efficiently within the confines of a given application domain. The term is often used in contrast to general-purpose architectures, such as CPUs , that are designed to operate on any computer program .
Donald Ervin Knuth (/ k ə ˈ n uː θ / [3] kə-NOOTH; born January 10, 1938) is an American computer scientist and mathematician.He is a professor emeritus at Stanford University.
The Hoover Institution Library and Archives is a research center and archival repository located at Stanford University, near Palo Alto, California in the United States.Built around a collection amassed by Stanford graduate Herbert Hoover prior to his becoming President of the United States, the Hoover Library and Archives is largely dedicated to the world history of the 20th and 21st centuries.
The above example would have a child nodes at each non-leaf node. Each node does an amount of work that corresponds to the size of the subproblem n passed to that instance of the recursive call and given by (). The total amount of work done by the entire algorithm is the sum of the work performed by all the nodes in the tree.
SICP has been influential in computer science education, and several later books have been inspired by its style. Structure and Interpretation of Classical Mechanics (SICM), another book that uses Scheme as an instructional element, by Gerald Jay Sussman and Jack Wisdom
In some cases, the alphabet used is simply that of the character encoding—resulting in, for example, a size of 256 in the case of (unsigned) ASCII. [ 14 ] : 732 The null links within the children of a node emphasize the following characteristics: [ 14 ] : 734 [ 5 ] : 336
