The invention discloses a quick parallel generating method for a multidimensional pseudo-
random sequence with uniform distribution characteristics, wherein the quick parallel generating method improves a classic coupled map lattice (CML) model according to the security requirement of the
cryptography, cancels
diffusion coefficients thereof, increases constant terms, limits the grid value to be within [0, 1] through modular operation, and achieves a novel coupled tent map lattice
system with the uniform distribution characteristics; and in addition, the pseudo-
random sequence is generated through user key conversion and initial vector conversion by utilizing a coupled tent map lattice
system model with the uniform distribution characteristics. The quick parallel generating method inherits the
coupling diffusion mechanism and the parallel iteration characteristics of the CML model, leads
system state tendency to achieve
ergodicity through the stretching and folding of the local grid tent map as well as the double nonlinear action of the modular operation, overcomes the defect of the CML model on security, and can generate the multidimensional pseudo-
random sequence with the uniform distribution characteristics in a parallel and quick manner.
