Czech Republic electronic signature scheme is based on the EU Directive 1999/93 EC. Currently there are three public certification service providers that passed the process of voluntary accreditation (Directive 1999/93/EC, article 2) and were granted by the regulation body of Czech Republic to provide the services as the accredited certification service provider according to Czech law. The paper is written from the perspective of the PKI supplier that participates strongly on the certification service provider support and also on the support of its customers.

We propose a new wireless PKI security scheme suitable for future mobile communication such as the third generation (3G). This scheme is based on two major elements, one is a trusted server, and the other is the dual public-key cryptosystems, to provide end-to-end security between mobile clients and the Healthcare Information System (HIS). Applications and services based on this WPKI scheme are also proposed.

Designated verifier signatures are privacy-oriented signatures that provide message authenticity only to a specified verifier but nobody else. We consider strong multi-designated verifiers such that knowledge of either one of designated verifiers’ private keys is required to verify the signature. We propose the first identity-based construction.
