    Authentication protocols are indispensable in wireless sensor networks. Commonly they are based on asymmetric cryptographic algorithms. In this paper we investigate all categories of finite fields suitable for elliptic curve cryptography on the ATmega128 microcontroller: \F{p}, \F{2^d}, and \F{p^d}. It turns out that binary fields enable the most efficient implementations

    A Note on Signature Standards

    No full text
    A major security goal for signature schemes is to prevent an adversary from producing new valid signatures even though he can receive valid signatures of any messages from the legitimate signer. On the one hand the security of elliptic curve signature schemes, as ECDSA, ECGDSA, or ECKCDSA, is based on the elliptic curve discrete logarithm problem, respectively on the security of the used hash function. On the other hand some special cases for ephemeral keys and signature components also have to be excluded to guarantee the security of the signature scheme. In this paper we are going to investigate some exceptional cases, which are not covered by current signature generation algorithms, but leak information on the private signature key

    The European Polysaccharide Network of Excellence (EPNOE) research roadmap 2040: Advanced strategies for exploiting the vast potential of polysaccharides as renewable bioresources

    No full text
    Polysaccharides are among the most abundant bioresources on earth and consequently need to play a pivotal role when addressing existential scientific challenges like climate change and the shift from fossil-based to sustainable biobased materials. The Research Roadmap 2040 of the European Polysaccharide Network of Excellence (EPNOE) provides an expert's view on how future research and development strategies need to evolve to fully exploit the vast potential of polysaccharides as renewable bioresources. It is addressed to academic researchers, companies, as well as policymakers and covers five strategic areas that are of great importance in the context of polysaccharide related research: (I) Materials & Engineering, (II) Food & Nutrition, (III) Biomedical Applications, (IV) Chemistry, Biology & Physics, and (V) Skills & Education. Each section summarizes the state of research, identifies challenges that are currently faced, project achievements and developments that are expected in the upcoming 20 years, and finally provides outlines on how future research activities need to evolve
