Unlinkability through Access Control: Respecting User-Privacy in Distributed Systems
, 2005 We propose a policy-based framework using RBAC (Role Based Access Control) to address the unlinkability problem in the context of correlating audit records generated from access to distributed services. We explore this problem in an environment where the

Cryptanalysis of a hybrid-structured onion routing scheme
Tongxin xuebao, 2013 SHI Jin-qiao et al's hybrid-structured onion routing scheme was analysed and some security flaws were found in their design.The first flaw was derived from the malleability of its cryptographic message format which could be exploited by attackers to ...

Proceedings of the Royal Society of Edinburgh: Section A MathematicsAbstract A Gordian unlink is a finite number of unknots that are not topologically linked, each with prescribed length and thickness, and that cannot be disentangled into the trivial link by an isotopy preserving length and thickness throughout. In this note, we provide the first examples of Gordian unlinks.

A Study on Unlinkability of RFID System Considering Restrictions of Real World
, 2006 RFID システムにおいて，ハッシュ関数等を用いてRFID タグの出力を毎回変更し，タ グ出力間のリンクを困難にすることにより，第三者によるユーザの位置追跡を防止する方式が提 案されてきた．しかしながら，タグ出力と同時に観測される位置情報には，現実世界の制約のため 強い相関が存在する．このため，第三者による位置追跡の危険性が依然としてあるといえる．本 発表では，現実世界の制約を考慮したRFID システムのリンク不能性について議論し，第三者に よる位置追跡能力との関係について考察する ...
