Coordinating processes with secure spaces
2003
Science of Computer Programming
Preserved Fulltext
Linda processes communicate by reading and writing messages in a globally visible data space, so a malicious process can launch any number of security attacks. ...
This paper presents the design of a new coordination model which extends Linda with ÿne-grained access control. The semantics of the model is presented in the context of a process calculus. ...
Coordination with secure spaces In this paper we present a coordination model, referred to as secure spaces, which extends Linda with ÿne-grained access control to the shared data space. ...

The unreliable communication channel used in message passing makes the election algorithm vulnerable to security attacks [7, 8] The unauthorized access may result in a security and privacy attack which ...
Different consensus algorithms exist for electing an entity as a coordinator and those are generally termed as coordinator election algorithms. ...

Moreover, our proposal extends the traditional data-driven coordination model with a more sophisticated pattern matching mechanism that supports a controlled access to the shared data. ...
In particular, three main aspects have attracted the attention of the coordination community: i) security in coordination; ii) integration of Linda with Web technologies (e.g., XML); iii) coordination ...

In this paper we outline the most significant security threats emerging in this context and we present a survey, in a process algebraic setting, of the most interesting shared data-space coordination languages ...
Shared data-space coordination languages, which provide a means to program interactions between decoupled entities abstracting away from their internal behavior, represent a powerful framework for programming ...
The threat in this case is that a malicious process can interfere with the entities which collaborate by using the space TS. ...

This paper discusses the security issues in data driven coordination languages. These languages rely on a data space shared by the agents and used to coordinate their activities. ...
We extend these languages with a main distinguishing feature, which is the possibility to define fine-grained security conditions, associated with every datum in the shared space. ...
In data driven coordination languages, security is generally enforced by using multiple (logical) spaces or by stating "Interaction Laws". With multiple spaces (e.g. ...
