The OAEP algorithm is a form of Feistel network which uses a pair of random oracles G and H to process the plaintext prior to asymmetric encryption. When combined with any secure trapdoor one-way permutation f {\displaystyle f} , this processing is proved in the random oracle model to result in a combined scheme which is semantically secure ...
AOHell was the first of what would become thousands of programs designed for hackers created for use with AOL. In 1994, seventeen year old hacker Koceilah Rekouche, from Pittsburgh, PA, known online as "Da Chronic", [1] [2] used Visual Basic to create a toolkit that provided a new DLL for the AOL client, a credit card number generator, email bomber, IM bomber, and a basic set of instructions.

An example of an asymptotically optimal algorithm not used in practice is Bernard Chazelle's linear-time algorithm for triangulation of a simple polygon. Another is the resizable array data structure published in "Resizable Arrays in Optimal Time and Space", [ 1 ] which can index in constant time but on many machines carries a heavy practical ...
The use of a new certificate format is an example of this. The format defined in the WTLS specification may not be appropriate for all the uses to which a certificate may be used. Client Implementation – As there are no official specifications which WTLS implementations must adhere to, many may use insecure cryptographic algorithms or key ...
Algorithm engineering focuses on the design, analysis, implementation, optimization, profiling and experimental evaluation of computer algorithms, bridging the gap between algorithmics theory and practical applications of algorithms in software engineering. [1]
Since algorithms are platform-independent (i.e. a given algorithm can be implemented in an arbitrary programming language on an arbitrary computer running an arbitrary operating system), there are additional significant drawbacks to using an empirical approach to gauge the comparative performance of a given set of algorithms. Take as an example ...
For combinatorial optimization, the quantum approximate optimization algorithm (QAOA) [6] briefly had a better approximation ratio than any known polynomial time classical algorithm (for a certain problem), [7] until a more effective classical algorithm was proposed. [8] The relative speed-up of the quantum algorithm is an open research question.
The code is distributed as free software under the MIT license. The R package arules contains Apriori and Eclat and infrastructure for representing, manipulating and analyzing transaction data and patterns. Efficient-Apriori is a Python package with an implementation of the algorithm as presented in the original paper.
