  1. Internet Main switch 128.198.162.51 128.198.162.52 128.198.162.53 NIC1 128.198.162.50 FC4 NIC2 10.0.0.1 Local switch Domain-controller 10.0.0.10 IIS 10.0.0.11 Win-XP 10.0.0.12 SIS Network Topology And IP assignments

  2. The Testbed • A 4-machine testbed has been built. • It contains the following: • Windows server 2003 with AD (The Domain Controller). • Windows server 2003 with IIS 6.0 (The web server). • Windows XP (a client). • Fedora Core 4 with IPtables-based firewall (A Gateway).

  3. The SIS Admin Tool • An admin tool is being developed to provide an easy-to-use GUI for setting up the SIS environment. • C# (C# Express 2005 IDE) has been used. • The main three components that we have so far are: • Public Key Infrastructure (PKI) setup. • Privilege Management Infrastructure (PMI) setup. • Certificates Management.

  4. Features: Creating new Certificate Authorities(CAs). Loading an existing CAs. Issuing a single digital cert (DC) and storing it in the AD, based on a GUI form. Issuing a bunch of DCs and storing them in the AD, based on a simple text file. Features: Creating new Attribute Authorities (AAs). Loading an existing AA. Issuing a single attribute cert (AC) and storing it in the AD, based on a GUI form. Issuing a bunch of ACs and storing them in the AD, based on a simple text file. PKI PMI

  5. Certificates Management • Check & validate a digital certificate. • Revoke a digital certificate. • Check & validate an attribute certificate. • Revoke an attribute certificate.

  6. Packages & techniques • OpenSSL [http://www.stunnel.org/download/binaries.html]: A wrapper compiled in binaries (exe file) has been used to implement the PKI part. • JCE-IAIK[http://jce.iaik.tugraz.at/]: A set of java APIs and implementations of cryptographic functionality that has been used to implement the PMI part. • IKVM.NET [http://www.ikvm.net]: an implementation of Java for the Microsoft .NET Framework that has been used to allow us using the IAIK java-based package in the .NET. • CryptLib [http://www.cs.auckland.ac.nz/~pgut001/cryptlib/] or [http://www.cryptlib.com]: a security toolkit that allows adding encryption and authentication services. * (We faced problems with it [files format & AC errors], therefore, we replaced it with the OpenSSL solution).
