Abstract:
Abstract. We describe the Personal Card Assistant, a scenario that brings together PDAs and smartcards. The underlying idea is that a PDA acts as a personal device for controlling a smartcard attached to it using an asymmetric key pair. We describe how such an approach can be used for creating digital signatures: in particular, we can circumvent the problems involved with untrusted document viewers in this context. We consider what sort of network infrastructure is required for using the PCA and outline how Jini can be used for integrating the PDA and smartcards into unknown service networks a mobile user is confronted with. 1
