For embedding process the watermark signal W are generated by using watermarking information bits b, chip rate r and PN sequence P.
Then it is multiplied by PN sequence used for embedding, summation over chip-rate window, yielding the correlation sum.
In Section III, a proposed authentication scheme is presented depending on the dynamic change of S-box in AES, the new secret key for every authentication process and the new PN sequence generator.
For every change in secret key a new S-box is derived from the standard one by permuting its columns and rows with the help of a new designed PN sequence generator.
The maximum length PN sequence that can be obtained from these polynomials is [2.
The starting position of the I-Channel PN sequence is such that the first chip is the "l" after the 19 consecutive "0"s.
As a PN signal has a very sharp autocorrelation at zero delay, it can be detected by correlation of the returned measurement signal with the known PN sequence.
The carrier frequency is amplitude-shift-key modulated with the PN sequence.

Note that the shift vector is used in the direction opposite that used in the embedding so that the PN sequences embedded in [p'.
