I am in the process of finalising the reviews for my WS book as well as planning my next conference trip. I am demonstrating our GOLD software (along with colleagues) at the supercomputing conferece in Florida on the 11th of November. I will be spending about 7-9 days there as I will be meeting my colleagues from MS Redmond too to discuss a project proposal. It will be my 4th trip to the states in a matter of months and unlike the other times I am not feeling 100% up to it. Still when duty calls one has to respond. It may also be a good opportunity to visit Cape Canaveral and the Kennedy space centre. I will not catch any launches unless they severly delay the rocket launch planned for the 25th of this month or bring the shuttle mission due on the 7th of Dec. forward. Still it iwll be a good experience. Couple of friends that i havent seen in a long time are visiting from Greece next week and i look forward to spending time with them. Weekend was also good, spent with familiar faces and colleagues.

Here is a game i found utterly annoying but couldn't stop playing. :-)

Report


This is a short report on access control issues for future research as they were identified by the GOLD project. Im off south again this week to try to identify potential project partners for the security proposal I am working on.

Happy Mondays



Contrary to my "wishful thinking" for a couple of weeks away, work commitments made me cancel my
away trip to Greece to attend and vote at the local elections. A ph.d. student I employed last month is
looking to start work on the BT project very soon and I need to be here to guide him. There is still a
lot of work to do my WS Book which is about a month late. This is due to several late reviews and
me being unable to chase each individual reviewer. I will have the reviews submitted by the
end of this month.

A report I am writing on future access control issues will be out soon.Iam addressing how architectures
negotiate and evaluate obligations, purpose of requests and regulations that cannot be expressed
in a policy document using oversimplified grammars such that of XACML.

more soon....

Oxford trip and other news.



Entries on blog are somewhat rare these days and main reason is that I am on the road a lot.Since
most of my weekend was spent working and networking I decided to take it easy or should i say easier today.
Our main objective for the rest of the project is to try to disseminate our results and in addition
try to get as many people as possible from within the eScience community to use our infrastructure.
For this reason I am visiting Oxford this week along with Paul. W. Through our contacts and mutual
efforts we found out about a number of projects including the Integrated Biology project (which I
knew of) which deals with large medical data sets to enable modelling of vital organs. The actual
scenarios regarding the data are similar to the chemical development data sets affiliated with
each step of the GOLD lifecycle. The potential of having the GOLD architecture being evaluated (more
specifically the GOLD security work) against other eScience project is both encouraging and exciting.
Another piece of work I have been recently involved, has been the evaluation of SecPAL which is a very
novel and rather interesting technology on Access Control. Collegues from MSR and Microsoft Redmond
introduced me to this technology for describing A.C. Policies. The clarity of its semantics makes the
Management of issues such as delegation easy and hence attractive. Will post a report on it soon....

pics back on line....


My photos section is now back online and updated with recent trips to NY and DC. Boy, that was a
lot of travelling in 12 months. I hope you enjoy the pictures, I like especially the one I took of myself
next to the rockets at the washington museum of science and technology. There is also a pic of the
Apollo 11 capsule. More soon.....
