  2. Transient-key cryptography - Wikipedia

    en.wikipedia.org/wiki/Transient-key_cryptography

    A private key is cross-certified using two other transient-key servers. Through independently operating servers, cross-certification can provide third-party proof of the validity of a time interval chain and irrefutable evidence of consensus on the current time. Transient-key cryptographic systems display high Byzantine fault tolerance. A web ...

  3. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    Both the logistic map and the sine map are one-dimensional maps that map the interval [0, 1] to [0, 1] and satisfy the following property, called unimodal . = =. The map is differentiable and there exists a unique critical point c in [0, 1] such that ′ =. In general, if a one-dimensional map with one parameter and one variable is unimodal and ...

  4. List of chaotic maps - Wikipedia

    en.wikipedia.org/wiki/List_of_chaotic_maps

    In mathematics, a chaotic map is a map (an evolution function) that exhibits some sort of chaotic behavior. Maps may be parameterized by a discrete-time or a continuous-time parameter. Discrete maps usually take the form of iterated functions. Chaotic maps often occur in the study of dynamical systems.

  5. Pairing-based cryptography - Wikipedia

    en.wikipedia.org/wiki/Pairing-based_cryptography

    If symmetric, pairings can be used to reduce a hard problem in one group to a different, usually easier problem in another group. For example, in groups equipped with a bilinear mapping such as the Weil pairing or Tate pairing, generalizations of the computational Diffie–Hellman problem are believed to be infeasible while the simpler decisional Diffie–Hellman problem can be easily solved ...

  6. Dyadic transformation - Wikipedia

    en.wikipedia.org/wiki/Dyadic_transformation

    xy plot where x = x 0 ∈ [0, 1] is rational and y = x n for all n. The dyadic transformation (also known as the dyadic map, bit shift map, 2x mod 1 map, Bernoulli map, doubling map or sawtooth map [1] [2]) is the mapping (i.e., recurrence relation)

  7. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    remove a (,) pair from the collection, unmapping a given key from its value. The argument to this operation is the key. Lookup, find, or get find the value (if any) that is bound to a given key. The argument to this operation is the key, and the value is returned from the operation.

  8. Poincaré plot - Wikipedia

    en.wikipedia.org/wiki/Poincaré_plot

    An RR tachograph is a graph of the numerical value of the RR-interval versus time. In the context of RR tachography, a Poincaré plot is a graph of RR(n) on the x-axis versus RR(n + 1) (the succeeding RR interval) on the y-axis, i.e. one takes a sequence of intervals and plots each interval against the following interval. [3]

  9. Gauss iterated map - Wikipedia

    en.wikipedia.org/wiki/Gauss_iterated_map

    Cobweb plot of the Gauss map for = and =. This shows an 8-cycle. This shows an 8-cycle. In mathematics , the Gauss map (also known as Gaussian map [ 1 ] or mouse map ), is a nonlinear iterated map of the reals into a real interval given by the Gaussian function :
