unusual facts about Symmetric-key algorithm



Acetylcholinesterase

In the central nervous system it is associated with PRiMA which stands for Proline Rich Membrane anchor to form symmetric form.

BMDFM

BMDFM (Binary Modular Dataflow Machine) is software, which enables running an application in parallel on shared memory symmetric multiprocessors (SMP) using the multiple processors to speed up the execution of single applications.

BRST

BRST quantization in Yang-Mills theories, a way to quantize a gauge-symmetric field theory

Classical unified field theories

These efforts, along with those of Forster, involved making the metric tensor (which had previously been assumed to be symmetric and real-valued) into an asymmetric and/or complex-valued tensor, and they also attempted to create a field theory for matter as well.

Hall algebra

Specializing q to 1, these symmetric functions become Schur functions, which are thus closely connected with the theory of Hall polynomials.

Hall–Littlewood polynomials

They are Schur functions when t is 0 and monomial symmetric functions when t is 1 and are special cases of Macdonald polynomials.

Holothuria forskali

All these groups tend to be radially symmetric and have a water vascular system that operates by hydrostatic pressure, enabling them to move around by use of many suckers known as tube feet.

Hydrogen atom

The solution of the Schrödinger equation (wave equations) for the hydrogen atom uses the fact that the Coulomb potential produced by the nucleus is isotropic (it is radially symmetric in space and only depends on the distance to the nucleus).

International Data Encryption Algorithm

In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991.

Key size

Mainstream symmetric ciphers (such as AES or Twofish) and collision resistant hash functions (such as SHA) are widely conjectured to offer greater security against known quantum computing attacks.

Location testing for Gaussian scale mixture distributions

The class of Gaussian scale mixture distributions contains all symmetric stable distributions, Laplace distributions, logistic distributions, and exponential power distributions, etc.

Michel Duflo

He introduced the Duflo isomorphism, an isomorphism between the center of the enveloping algebra of a finite-dimensional Lie algebra and the invariants of its symmetric algebra.

N! conjecture

In fact, we can obtain in this manner the Schur functions, the Hall–Littlewood symmetric functions, the Jack symmetric functions, the zonal symmetric functions, the zonal spherical functions, and the elementary and monomial symmetric functions.

PCGS

Preconditioned conjugate gradient square method, a variant of the preconditioned conjugate gradient method - an algorithm for the numerical solution of systems of linear equations whose matrix is symmetric and positive-definite.

Rhodium-catalyzed hydrogenation

Common ligands for asymmetric hydrogenation include DIOP, DIPAMP, BPPFOH, BPPM, and other Robinson–Foulds metric

The treedist program in the PHYLIP suite offers this function, as does the RAxML standard package and the DendroPy Python library (under the name "symmetric difference metric").

Shell theorem

On the other hand, if we relax the conditions, and require only that the field everywhere outside a spherically symmetric body is the same as the field from some point mass at the centre (of any mass), we allow a new class of solutions given by the Yukawa potential, of which the inverse square law is a special case.

Xeon

At most two Foster processors could be accommodated in a symmetric multiprocessing (SMP) system built with a mainstream chipset, so a second version (Foster MP) was introduced with a 1 MB L3 cache and the Jackson Hyper-Threading capacity.
