提出一种动态加密技术在Ad—hoc网络中的应用,该方案的优点在于将加密以后的密文当作加密操作的一个种子密钥,有效提高系统的安全性;并将加密操作贯穿到通信系统中的全部过程以让系统中的所有节点具有连续动态密钥生成和同步机制;该加密系统能节省大量网络带宽,这对Ad-hoc网非常有意义,试验结果验证了该方案的合理性和有效性。
A new dynamic encryption application in Ad-hoc networks was proposed. The advantages of the method are as follows: the previous ciphertext can be used as a seed of the new encryption process, encryption process takes effect in all the communication process by continuous dynamic key generation and synchronization, it also decreases the system bandage to a great degree, which is valuable to the Ad-hoc circumstance. Test results verified the rationality and effectiveness of the novel encryption method.
