Method and apparatus for permuting input data and recording medium having stored thereon a program for executing permutation
摘要:
Permuted data (u1′, u2′, . . . , um′) of input data (u1, u2, . . . , un) expressed by the relationship [ u 1 ′ u 2 ′ ⋮ u m ′ ] = P ⁡ [ u 1 u 2 ⋮ u n ] , are obtained by expressing the permuted data uj′ by uj′=ui′+Di, where j≠i and calculate uj′ for all of j.
