We discuss different fixed rotation s effect to RC6-I (A variety of RC6 which replace the quadratic function by identity function) at first, and prove that the invulnerability to differential attack is best when the fixed rotation is equal to lgw.

Finite element analysis of QFP structure subjected to circular displacement loadings;

Study on LDPC codes based on cyclic-shift identity matrix;

A kind of image encryption algorithm is presented based on chaos theory and cycle shift.

The cyclic shift character of base phasor in DFT is proposed and approved first in this paper.

Aimed at solving the problem of low data rate of direct sequence spread spectrum underwater acoustic communication and that of complexity of the receivers of M-ary spread spectrum underwater acoustic communication,cyclic shift keying spread spectrum underwater acoustic communication is proposed based on the good characteristic of spread sequences.

Cyclic shift permutation structure is an important part of partial parallel decoder for quasi-cyclic LDPC codes.

Rotation normalization was realized by circular shift of the feature elements to get the invariant texture feature vector.
