Substitution Cipher

Substitution ciphers, methods of encrypting text by replacing letters or words with others, remain a relevant area of research, particularly in the context of securing and analyzing large language models (LLMs). Current work focuses on applying and adapting substitution techniques for both attacking (e.g., "jailbreaking" LLMs) and improving (e.g., data augmentation for machine translation) these models, often leveraging algorithms like Byte Pair Encoding and unigram language models for segmentation and analysis. These advancements contribute to a better understanding of LLM vulnerabilities and offer novel approaches to enhance their robustness and efficiency in natural language processing tasks.
