Abstract

Attribute-based Encryption (abe) allows for implementing fine-grained decentralized access control based on properties or attributes a user has. Thus, there is no need for writing detailed, user-based policies in advance. This makes abe in particular interesting for implementing security mechanisms in dynamic environments such as ubiquitous computing, disaster management, or health-care. For supporting the latter two application areas, common abe approaches lack one important feature: break-glass, i. e., the controlled overriding of access control restrictions.

In this paper we present an integration of break-glass into an approach for end-to-end secure information sharing using abe techniques.
