To begin with, theory of FCSR and its sequence is summarized and investigated. Furthermore, emphasis is placed on the vaule of 2-adic complexity. A conclusion is drawn that the vaule lies in the relation between 2-adic complexity and lineai complexity of a same seqence. Fact that there exists sequence with high linear complexity but low 2-adic complexity is given and analyzed. The value of 2-adic complexity in cryptanalysis can be directly drawn from the very fact. A series of problems are opened based on the value and discussions are done in various depth. Some good results are obtained in these problems such as the 2-adic complexity distribution of periodic sequences and the stability of 2-adic complexity. The value of FCSR in stream cipher design is discussed at the same time.

From our results we know that the average error of the Lagrange interpolation sequence and the Hermite interpolation sequence based on the Chebyshev nodes in the 1-fold integrated Wiener space equal weakly to the average error of their corresponding optimal approximation polynomial in the 1-fold integrated Wiener space,and as a kind of information-based operation,they have simple form and their recover functions are polynomials,in the 1-fold integrated wiener space,their average error equal weakly to the corresponding minimal information radius whose permissible information operators class is function values.

Firstly,the wavelet-based contourlet coding using an SPIHT-like algorithm is utilized on the plain image,and as a result,the compressed datum stream could be achieved which is then mapped to a 3D bit matrix. Afterward,a chaotic sequence is generated by Lorenz chaotic map,and it is preprocessed to a bit sequence which is used to permute and substitute the elements of the 3D bit matrix achieved above. In the end,the processed 3D matrix is mapped back to datum stream,and the encrypted compressed image could be achieved if decoding and inverse transform are performed on the datum stream.
