In this study, we assessed Diaconu's strategy [17] and found a dangerous vulnerability in the circular shift procedure.
The permutation phase scrambles pixels by bit-level circular shift, which updates the pixel positions and generates new pixel values.
Compute the circular shift steps [N.sub.shifts] and direction [D.sub.shifts] of each row.
bitwise AND, bitwise XOR and circular shift operation.
The key expansion module involves the bitwise AND, bitwise XOR, and circular shift operation.
In the case when m=4 there is an extra step the most significant word [k.sup.i+3] is circular shifted right by 3 and XOR'ed with [X.sup.i+1], circular shifted to the right by 1 and XOR'ed with the constant [C.sup.j.] as [k.sup.i] is the key used in the present round it will no longer be needed and is overwritten in every round.
Clearly, M is a circular shift of L, since [y.sub.i+1] = [x.sub.i] for i = 0,1, 2, 3,4, mod 5.
Then R is a circular shift of L but now this is not a general feature of non-trivial r-colorings on standard diagrams of THK (3,n)'s (see, for instance, the 5-coloring of THK(3,2) on the right-hand side of Figure 4, or the 7-coloring of THK(3, 8) in Figure 6).
For prime r > 5 and odd [psi](r), we construct a non-trivial r-coloring on the standard diagram of THK(3, [psi](r)) such that the R sequence is a circular shift of the L sequence (Theorem 1.3).
Similar to these two methods, in this paper, [p.sub.m,n] is designed as a circular shift sequence within the subpulse [t.sub.b].
Then the new sequences are sent to circular shift module and an optimal circular shift sequence is sought to maximize the autocorrelation performance of the RadCom system.
The new circular shifts the emphasis to a physical branch.
