【摘要】 传输介质的开放性,使无线局域网存在与生俱来的信息安全风险,802.11i和IPSec协议是解决该问题的两种主流技术途径。采用定性和半定量的方法,对这两种协议的加密、认证和消息完整性等安全机制,以及抗攻击性能,进行了对比分析,并考虑兼容性和成本等实际因素,为无线局域网的信息安全,提供了一些有一定参考价值的建议。更多还原

【Abstract】 Risks are inherent in wireless LAN(WLAN).802.11i standard and IPSec protocol are two main technologies to mitigate such risks.Based on qualitative and semi-quantitative analysis of their security features(confidentiality,authentication,integrity,etc.),and consideration of practical factors,such as compatibility and cost,some suggestions are made for information security in WLAN.更多还原
