Beyond End-to-End Recovery: Towards a Better Understanding of LLM Steganography via Rolewise Decomposition
Rolewise decomposition reveals that end-to-end recovery rates mask significant per-role weaknesses in LLM steganography — insights useful for covert-channel detection.

arXiv:2610.30516v1 Announce Type: new Abstract: In large language model (LLM) steganography, an encoder hides a private message in an otherwise ordinary response, as text transmitted to a decoder, who attempts to recover it. The success of this private-message transmission is commonly measured through end-to-end (E2E) recovery, which checks whether the decoder correctly reconstructs the private message. However, E2E recovery cannot distinguish encoding failures from decoding failures or reveal
Editorial Analysis
As LLM-generated text becomes ubiquitous, understanding steganographic channel capacity per role helps defenders anticipate covert data-exfiltration techniques.
