| 摘 要： | 利用BP神经网络,对非线性系统产生的混沌序列进行学习,逼近该非线性系统的映射特征,从而使自身具有混沌特性,成为具备混沌输出能力的神经网络,建立了基于神经网络的混沌序列产生模型(CGNN).此方法利用具有学习能力的神经网络,它不需要针对某一种非线性映射设计单一的系统结构.并利用DSP技术在CGNN基础上,制成了混沌神经网络协处理机插板,将其产生的混沌序列作为密钥,用于信息的保密通信.

| Abstract: | Back propagation neural network and chaos dynamics are combined in this paper. The global-optimum and dynamic-adjusting neural network is trained by the chaos series from non-linear system so as to approach the mapping feature of that system. So, a chaos generation scheme based on the neural network is proposed. By using nonlinear neural network with learning ability, this scheme doesn't have to be designed to be a single system structure for a certain nonlinear chaotic map. At last, using DSP technology, a Chaos Neural Network Co-processer Flashboard is made based on the CGNN. The chaos is used as a encrypeted key in the encryption telecommunication. |
