最後作者論述了自己對系統為實施安全協議所做的調整與優化；同時筆者也對進一步提高系統的可靠性和實時性提出了自己的建議，並在操作系統與協議棧的無縫連接方面進行了初步探討。 -
This paper has introduced the principle of isakmp, a protocol used in dynamical key exchange, and has accounted for the theory of ipc ( inter - process communication ) and a kind of new socket type pf _ key, as well as their messaging activity and related operations. the paper has mainly analyzed the procedure of building messages in kernel and its communication with application, the methods of managing messages and sadb. finally, it has presented a design of ipc ( inter - process communication ) between kernel and application according to pf _ key protocol, which makes various users communicate with each other on different channels created dynamically
本文簡要介紹了在ipsec中實現動態密鑰交換使用的通用框架協議? ? isakmp的基本原理；詳細闡述了進程間通信機制和pfkey協議的基本原理、消息行為及相關操作；著重分析了系統內核消息構造及其與應用層通信的過程和系統內核處理消息、管理安全關聯數據庫（ sadb ）的方法；最終提出了利用pfkey套介面協議在系統內核與應用層之間進行通信，為不同的用戶對動態地建立不同的安全通道的設計方案。
