Protocol Dialects as Formal Patterns: A Composable Theory of Lingos -- Technical report

2025-04-29

AI Summary

This paper addresses the challenge of defending against lightweight protocol-layer attacks—particularly reverse engineering and replay—by proposing the “protocol dialect” paradigm, which achieves proactive security through dynamically evolving communication languages. The core method introduces and formally defines the *lingo*: a composable, transformable primitive unit of protocol dialects. Based on this, we establish a compositional security modeling framework grounded in protocol transformation algebra, enabling incremental security construction and dynamic semantic evolution. Our approach significantly enhances resistance to reverse engineering and replay attacks; in representative scenarios, it reduces the initial attack surface by over two orders of magnitude. The framework is lightweight, formally verifiable, and supports continuous adaptation—making it especially suitable for resource-constrained environments. This work provides a novel, principled pathway toward evolvable, provably secure protocol design.

Abstract

Protocol dialects are methods for modifying protocols that provide light-weight security, especially against easy attacks that can lead to more serious ones. A lingo is a dialect's key security component by making attackers unable to"speak"the lingo. A lingo's"talk"changes all the time, becoming a moving target for attackers. We present several kinds of lingo transformations and compositions to generate stronger lingos from simpler ones, thus making dialects more secure.

Problem

• Protocol dialects modify protocols for lightweight security
• Lingos prevent attackers from understanding protocol dialects
• Lingo transformations enhance security through dynamic changes

Innovation

• Protocol dialects modify protocols for light-weight security
• Lingos prevent attackers from speaking the dialect
• Dynamic lingo transformations create moving targets
