Description: 彩色图像加密基于三维混沌系统的彩色图像加密新算-A bstr act : The 1D chaotic image encryption method is reported with appropriate performances by using the appropriate
complexity, pseudo- randomness and extreme parameter sensitivity of chaotic sequences but with smaller key space as its serious
drawback compared with others.So, a new image encryption method based on 3D chaotic system is proposed in this paper,
which can not only increase secret key space, but also tone up ability to deciphering.And in this paper, the pixel value of
cipher- image used to get secret key and the feedback used in encryption process improve greatly the performances of the
diffusion function.The method is proved to work well by the result, because of its larger secret key space and high speed of
encryption and so on.

Description: This literature review glances at the research that has been published in the area of chaos cryptography along with
cryptanalysis of chaotic cryptosystem. It compares and contrasts the work done in different research papers towards the
designing and cryptanalysis of chaotic cryptosystem for the validity of cryptosystems and improvement in encryption
techniques. This review analyzes the role that chaotic cryptosystem has played and will play in the future relative to the
security. By reviewing the papers, it is the objective to design a number of secured cryptosystem based on different families
of chaotic sequences using various encryption techniques. The work can arrive with more efficient and robust chaotic
cryptosystem so as to provide data security, privacy and to preserve the future of network security and prevail secured
