NEMESYS: Network Message Syntax Reverse Engineering by Analysis of the Intrinsic Structure of Individual Messages
Infers approximate field boundaries within individual binary-protocol messages from changes in bit congruence, and introduces Format Match Score to compare inferred segmentation with known protocol dissectors.
Scope and limitations
Requires plaintext payloads. Evaluation covers DNS, DHCP and NTP with protocol-tuned parameters. Single-byte fields are not inferred; zero-filled fields, character sequences and pseudo-random values can cause errors. FMS needs known field boundaries for validation. The output is approximate segmentation, not field semantics, a state machine or complete application/device behavior.
Why it fits this collection
Provides a foundational method for reconstructing wire-message structure from observed traffic.
