提出一种组播通信安全加密方案.混沌神经网络复杂的非线性动力学特性主要包括序列轨迹的无法预测性和混沌吸引子分类的不规则性.组密钥管理协议LKH优势在于密钥更新快和更新代价小,适合大型组播通信环境.该方案是把混沌神经网络和组密钥管理协议的优势相融合应用在安全组播通信中.理论分析表明该方案具有良好的随机性、复杂度、速度快等密码学特点.在Altera DE2FPGA硬件平台上进行算法设计与仿真,仿真结果表明该算法只占用约5%左右的硬件资源,时钟可达50 MHz,能够满足安全组播通信的要求.
This paper proposes a multicast communication security encryption scheme.The complex nonlinear dynamics of chaotic neural network mainly include the unpredictability of sequence trajectories and the irregularity of chaotic attractor classification.The advantage of group key management protocol LKH lies in the key update Which is suitable for large-scale multicast communication environment.This scheme uses the advantages of chaotic neural network and group key management protocol in the secure multicast communication.The theoretical analysis shows that the scheme has good randomness and complexity , Fast speed and other cryptographic features.Algorithm design and simulation on Altera DE2FPGA hardware platform show that the algorithm only takes about 5% of the hardware resources, the clock up to 50 MHz, to meet the requirements of secure multicast communication.
