Self-Adaptation and Secure Information Flow in Multiparty Structured Communications: A Unified Perspective

TL;DR

This paper introduces a unified model for multiparty structured communications that integrates self-adaptation mechanisms with security guarantees, ensuring correct execution and security compliance during interactions.

Contribution

It proposes a novel model combining self-adaptive communication protocols with security enforcement, addressing violations dynamically to maintain protocol integrity.

Findings

Security violations trigger adaptation mechanisms.

Type soundness ensures correct global protocol execution.

The system maintains security while adapting to violations.

Abstract

We present initial results on a comprehensive model of structured communications, in which self- adaptation and security concerns are jointly addressed. More specifically, we propose a model of self-adaptive, multiparty communications with secure information flow guarantees. In this model, security violations occur when processes attempt to read or write messages of inappropriate security levels within directed exchanges. Such violations trigger adaptation mechanisms that prevent the violations to occur and/or to propagate their effect in the choreography. Our model is equipped with local and global mechanisms for reacting to security violations; type soundness results ensure that global protocols are still correctly executed, while the system adapts itself to preserve security.
