In this paper, a new watermarking using cell neural network with hyper-chaotic cellular neural network (HCCNN) is proposed. In the scheme, the pixel values of the image are used to the input of the HCCNN. The outputs of the HCCNN are encrypted by the public key system, and then are embedded into the LSBs of the original image. The receiver can verify the suspected image with the signer's public key...
The design of an efficient one-way hash function with good performance is a hot spot in modern cryptography researches. In this paper, a hash function construction method based on cell neural network (CNN) with hyper-chaos characteristics is proposed. The chaos sequence generated by iterating CNN with Runge-Kutta algorithm, then the sequence iterates with every bit of the plaintext continually. Then...
In this paper, we give an investigation on the performance of cellular dual-hop cooperative communication systems with regenerative relays over flat Rayleigh fading channels. M-ary phase-shift keying (M-PSK) is considered. Two linear diversity reception techniques are adopted in the destination, i.e.,maximal-ratio combining (MRC) and selection combining (SC).We first derive the symbol error rate (SER)...
