ABSTRACT Toward Usable Access Control for End-users: A Case Study of Facebook Privacy Settings
, 2012
"... Many protection mechanisms in computer security are designed to enforce a configurable policy. The security policy captures high-level goals and intentions, and is managed by a policy author tasked with translating these goals into an implementable policy. In our work, we focus on access control pol ..."

the desired policy into the implemented policy. Specifying correct security policies is known to be a difficult task, and prior work has contributed policy authoring tools that are more usable than the prior art and other work has also shown the importance of the policy author being able to quickly understand
GEO-RBAC: A spatially aware RBAC
- In ACM Symposium on Access Control Models and Technologies (SACMAT’06
, 2005
"... Securing access to data in location-based services and mobile applications requires the definition of spatially aware access control systems. Even if some approaches have already been proposed either in the context of geographic database systems or context-aware applications, a comprehensive framewo ..."

the feature (the road, the town, the region) in which they are located. To make the model more flexible and re-usable, we also introduce the concept of role schema, specifying the name of the role as well as the type of the role spatial boundary and the granularity of the logical position. We then extend GEO

Rührmair: Physical Unclonable Functions in Cryptographic Protocols: Security Proofs and Impossibility Results. Cryptology ePrint Archive, Report 2012/228
, 2012
"... We investigate the power of physical unclonable functions (PUFs) as a new primitive in cryptographic protocols. Our contributions split into three parts. Firstly, we focus on the realizability of PUF-protocols in a special type of stand-alone setting (the “stand-alone, good PUF setting”) under minim ..."

First, OT and KE protocols whose security is solely based on PUFs are generally impossible in the PAM. More precisely, one-time access of an adversary to the PUF after

Usability and Acceptance of UF-IBA, an Image-Based Authentication System Copyright Material IEEE Paper No. ICCST-2007-xxxx
"... Abstract – Text-based username-password systems have been traditionally used in authenticating users before allowing them access to online services. Psychological studies [1] have shown users ’ inability to recall random sequences of alpha-numeric strings, which theoretically make the best passwords ..."
