As part of this doctoral seminar, we will create a comprehensive reading list . From the list, we will select better ones for review/presentation and discussion in class. The reading lists will contain papers related to trust, access control, as well as intrusion/survivability management. Based on the number of students and interest, we may narrow down to only few topics. The students are welcome to suggest new additions.
All the papers should be available online.
