Private information escrow bound to multiple conditions
We propose two variants of a protocol that provides users' private information escrow capability bound to multiple set of conditions in a federated single sign-on environment using trusted platform module (TPM) and secure processor technologies. The first variant assumes the existence of a trusted anonymity revo- cation manager, while the second variant does not. Cryptographic techniques, such as identity-based re- encryption and custodian-hiding encryption, are ap- plied in our protocol. A performance analysis of our protocol is provided to show that our protocol achieves a better performance in comparison to the existing anonymous credential approach. This is es- pecially true when a user interacts with many service providers in a session. The security properties pro- vided by both variants of our protocol are discussed.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
