A Theory of Composable Lingos for Protocol Dialects

2026-03-20

AI Summary

This work addresses the risk that lightweight attacks may escalate into severe security threats by proposing a “lingo”-based approach to protocol security enhancement. By formally modeling the core security components—referred to as lingo—within protocol dialects, the method designs composable and synthesizable generic patterns and integrates moving target defense principles to dynamically alter communication characteristics. This enables the automatic transformation of any protocol into a dialect variant with lightweight security guarantees. The contributions include the first composable formal framework for lingo, a general-purpose construction mechanism for protocol dialects, and empirical validation of the approach’s effectiveness and practicality across multiple protocols.

Abstract

Formal patterns are formally specified solutions to frequently occurring distributed system problems that are generic, executable, and come with strong qualitative and/or quantitative formal guarantees. A formal pattern is a generic system transformation which transforms a usually infinite class of systems in need of the pattern's solution into enhanced versions of such systems that solve the problem in question. In this paper we demonstrate the application of formal patterns to protocol dialects. Dialects are methods for hardening protocols so as to endow them with light-weight security, especially against easy attacks that can lead to more serious ones. A lingo is a dialect's key security component, because attackers are unable to ''speak'' the lingo. A lingo's ''talk'' changes all the time, becoming a moving target for attackers. In this paper we present several formal patterns for both lingos and dialects. Lingo formal patterns can make lingos stronger by both transforming them and by composing several lingos into a stronger lingo. Dialects themselves can be obtained by the application of a single dialect formal pattern, generic on both the chosen lingo and the chosen protocol.
