This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many commercial and civilian government organiza...

Scalable Access Controls for Lineage

Lineage stores often contain sensitive information that needs protection from unauthorized access. We build on prior work for security and privacy of lineage information, focusing on complex conditions and scalable administration. We use Attribute-Based Access Control (ABAC) to express conditions based on many attributes, instead of roles. We then make administration and management more scalabl...
