Abstract :
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.
