Abstract. A substantial number of micropayment schemes in the literature are based on distributing the cost of a digital signature over several successive micropayments (e.g. Paywo...
The implementation of a standard PKI in a mobile ad hoc network (MANET) is not practical for several reasons: (1) lack of a fixed infrastructure; (2) a centralized certification au...

Abstract. Besides the pure technical features, the usability of a PKIenabled application plays a crucial role since the best security application will fail in practice if its usabi...
Despite a legal framework being in place for several years, the market share of qualified electronic signatures is disappointingly low. Mobile Signatures provide a new and promisin...
The use of PKI in large scale environments suffers some inherent problems concerning the options to adopt for the optimal cost-centered operation of the system. In this paper a Mar...

Abstract. At present, network users have to manage a set of authentication credentials (usually a username/password pair) for every service with which they are registered. Single S...
Abstract. This paper discusses the technical and management experience gained in the day-by-day operation of the EuroPKI infrastructure. First the context where EuroPKI was born is...

We present a new threshold password-based authentication protocol that allows a roaming user(a user who accesses a network from different client terminals) to download a private k...
Abstract. In many cryptographic applications it is necessary to generate elliptic curves (ECs) with certain security properties. These curves are commonly constructed using the Com...
