摘要

本文介绍了智能卡中安全计算密钥树的ASN.1脚本。密钥树用于各种协议,如AKA或EAP,这些协议将部署在下一代无线网络(WLAN、WiMAX、EUTRAN…)中。它们提供快速重新身份验证、移交管理或移动IP支持等服务。我们提出了一种基于智能卡的可信计算体系结构。我们建议使用两种方法,一种是使用嵌入式预定义键生成器的静态树,另一种是使用脚本构建的动态树。最后详细介绍了用于动态键树计算的ASN.1脚本。

Smart Card Benefits for Trusted Processing of Keys-Tree in WLANs
In this paper we introduce ASN.1 scripts, securely computing cryptographic keys-trees, in smart cards. Keys-trees are used by various protocols such as AKA or EAP that are going to be deployed in next generations of wireless networks (WLAN, WiMAX, EUTRAN…). They provide services such as fast re-authentication, handover management, or Mobile IP support. We propose a trusted computing architecture for these structures, based on smart cards. We suggest two kinds of approaches, static trees working with embedded pre-defined keys generators, and dynamic trees, built from scripts. Finally we detail ASN.1 scripts, designed for dynamic keys-trees computing.
