由于诸多物理限制,在移动AD-HOC网络中实现节点认证存在许多困难,自发组网形式排除了采用单钥体制的可能,因为并不存在TTP或统一的管理机构,基于PKI的认证方法提供了较好的灵活性和安全性。
Due to many physical limitations, there are many difficulties in implementing node authentication in mobile AD-HOC networks. The spontaneous networking eliminates the possibility of using a single-key system because there is no TTP or unified management mechanism and PKI-based authentication provides Better flexibility and security.
