In cryptography , the term pseudorandom permutation , abbreviated PRP , refers to a function that cannot be distinguished from a random permutation that is, a permutation selected at random with uniform probability, from the family of all permutations on the function s domain with practical effort. A pseudorandom permutation family is a collection of pseudorandom permutations, where a specific permutation may be chosen using a key. The idealized abstraction of a block cipher is a truly random permutation. If a distinguishing algorithm exists that achieves significant advantage cryptography advantage with less effort than specified by the block cipher s security parameter this usually means the effort required should be about the same as a brute force search through the cipher s key space , then the cipher is considered broken at least in a certificational sense, even if such a break doesn t immediately lead to a practical security failure.

Orphan date February 2009 Notability Products date August 2011 A pseudorandom encoder is an electro mechanical device used for measuring distance and finding position. It is different from the conventional absolute and incremental encoder in its disk pattern, which gives it aspects of the other two designs. The disk of a pseudorandom encoder has an evenly spaced notch design just as an incremental encoder to measure distance. A second track of code is used to find the position just like an absolute encoder however, an absolute encoder tells position from reading from multiple parallel tracks while a pseudorandom encoder uses one single track. This aspect allows pseudorandom rotary encoders to have smaller diameters and larger through holes. To know its position, the encoder must first move a certain distance to read the code. This distance is generally small, about 1 2 degrees for rotary encoders and 1 mm for linear encoders, though this idiosyncrasy does hinder its usefulness in some applications such as trackball track balls since position is not immediately known when the system starts. ref cite web url http www.virtualabsolute.com VAoverview.htm title A New Kind of Encoder virtualabsolute.com ref See also Rotary encoder References reflist Category Dimensional instruments ... more details

In cryptography , a pseudorandom function family , abbreviated PRF , is a collection of efficiently computable Function computer science functions which emulate a random oracle in the following way no efficient algorithm can distinguish with significant Advantage cryptography advantage between a function chosen randomly from the PRF family and a random oracle a function whose outputs are fixed completely at random . Pseudorandom functions are vital tools in the construction of cryptographic primitive s, especially secure encryption encryption schemes . Pseudorandom functions are not to be confused with Cryptographically secure pseudorandom number generator pseudorandom generators PRGs . The guarantee of a PRG is that a single output appears random if the input was chosen at random. On the other hand, the guarantee of a PRF is that all its outputs appear random, regardless of how the corresponding inputs were chosen, as long as the function was drawn at random from the PRF family. A pseudorandom function family can be constructed from any pseudorandom generator, using, for example, the construction given by Goldreich, Shafi Goldwasser Goldwasser , and Micali. ref Oded Goldreich , Shafi Goldwasser , Silvio Micali 1986 How to Construct Random Functions , Journal of the ACM , vol.33, no.4, p.792 807. doi 10.1145 6490.6503 http theory.lcs.mit.edu cis pubs shafi 1986 jacm.pdf preprint http www.math.weizmann.ac.il oded ggm.html web page and preprint ref See also Pseudorandom permutation References references Category Theory of cryptography Category Cryptographic primitives Category Pseudorandomness de Pseudozuf llige Funktion he ... more details
In computational complexity theory and cryptography , the existence of pseudorandom generator s is related to the existence of one way function s through a number of theorems, collectively referred to as the pseudorandom generator theorem .

A PRBS is random in a sense that the value of an math a j math element is independent of the values of any of the other elements, similar to real random sequences. It is pseudo because it is deterministic and after math N math elements it starts to repeat itself, unlike real random sequences, such as sequences generated by radioactive decay or by white noise. The PRBS is more general than the n sequence , which is a special pseudo random binary sequence of n bits generated as the output of a linear shift register.

The sequence is not truly random in that it is completely determined by a relatively small set of initial values, called the PRNG s state , which includes a truly random seed . Although sequences that are closer to truly random can be generated using hardware random number generator s, pseudorandom numbers are important in practice for their speed in number generation and their reproducibility, and they are thus central in applications such as simulations e.g., of physical systems with the Monte Carlo method , in cryptography , and in procedural generation . Good statistical properties are a central requirement for the output of a PRNG, and common classes of suitable algorithms include linear congruential generator s, lagged Fibonacci generator s, and linear feedback shift register s. Cryptographic applications require the output to also be unpredictable, and more elaborate designs, which do not inherit the linearity of simpler solutions, are needed.
