The next GGF is only a week away, as usual with plenty of interesting sessions to attend. On top of that, there's the GridWorld Japan expo that may attract some of you as well.
I would like to make some advertising for the security area session on Thursday morning (9am). Besides the usual formalia, we will get some thought-provoking ideas on the use of Identity-Based Cryptography in Grid Security, presented by Hoon Wei Lim.
Abstract as follows:
The majority of current security architectures for grid systems use
public key infrastructure (PKI) to authenticate identities of grid
members and to secure resource allocation to these members.
Identity-based cryptography (IBC) has some attractive properties which
seem to align well with the demands of grid computing, for example, it
is certificate-free and uses small key sizes. More importantly, an entity's public key can be computed on-the-fly based on their identity.
In this talk, we present the use of identity-based techniques to provide
an alternative grid security architecture. Our proposal exploits some interesting properties of hierarchical identity-based cryptography (HIBC) to replicate security services provided by the grid security infrastructure (GSI) of the Globus Toolkit.
Take care, and hope to see many of you next week!
PS. Don't forget to read and make a statement on your support and/or criticism of the security-related documents that are currently in public comment!
