嵌入式設備接入Internet 是當今嵌入式系統(tǒng)發(fā)展的一個重要趨勢,但是Internet 提供的開放性網(wǎng)絡環(huán)境并不保障接入嵌入式系統(tǒng)的安全性。本文在分析嵌入式網(wǎng)絡安全特點和研究IPSec 協(xié)議基礎上，研究了目前嵌入式網(wǎng)絡安全特點，并對系統(tǒng)中的關鍵技術做了一一解析，包括VPN 及其隧道技術的應用和身份認證等，提出了一個基于IPSec 新型嵌入式系統(tǒng)安全的安全模式和實現(xiàn)方式。實驗結果表明：基于IPSec 協(xié)議的嵌入式系統(tǒng)具有良好的可擴展性和安全性能。
關鍵詞：嵌入式系統(tǒng) IPSec 網(wǎng)絡安全
Abstract: The study on system security becomes an important problem in network security domain.The paper mainly focuses on the security of embedded system, enunciate the shortage of traditional network security system, and we bring up a new network security system integrating the IPSec and SSL protocol, analysis some key technologies. Finally, it summarizes the research results and lists the functions to be improved.
