    Elliptic Curve Cryptography in X.509-based PKI
    (SICHERHEIT 2008 – Sicherheit, Schutz und Zuverlässigkeit. Beiträge der 4. Jahrestagung des Fachbereichs Sicherheit der Gesellschaft für Informatik e.V. (GI), 2008) Hick, Sibylle; Lo Iacono, Luigi
    In recent years a new category of digital signature algorithms based on Elliptic Curve Cryptography (ECC) has taken place besides well known schemes as RSA or DSA. So far it is, however, still not obvious how ECC-based signature schemes can be integrated in X.509-based Public Key Infrastructures (PKI).This paper briefly introduces cryptographic basics of signature schemes based on elliptic curves and points out the necessary cryptography parameters that are important in this context. Afterwards the structure and the encoding of X.509 certificates and Certificate Revocation Lists (CRL) are discussed regarding the integration of ECC public keys and ECC signatures respectively. The paper closes with exemplary implementations of ECC-based security systems.

    Towards best practices for biometric visa enrolment
    (BIOSIG 2010: Biometrics and Electronic Signatures. Proceedings of the Special Interest Group on Biometrics and Electronic Signatures, 2010) Rahmun, Fares; Hick, Sibylle
    Public sector applications - e.g. the process of application of a biometric visa - are connected to different kinds of technical, organisational, and legal requirements. But how can those requirements and recommendations be retrieved, analysed and described? The German federal government has taken part in the European pilot project BioDEV II in order to gain comprehensive experiences regarding the handling and processing of biometric visa. Furthermore, the Federal Office for Information Security (BSI) publishes technical guidelines that address different topics in information security. In this context, the Technical Guideline Biometrics for Public Sector (TR Biometrics) has been published in order to describe technical and organisational requirements and recommendations in the context of biometrics for electronic identity documents. In this paper the authors give an overview of the pilot project BioDEV II and show how the results have been introduced in the TR Biometrics.
