Understanding the Security Boundary of Obfuscation-based On-Device LLM Protection
This paper formalizes a set of obfuscation primitives, defined as dual-tuples of linear computations satisfying specific algebraic properties, and demonstrates that the matrix-level weight transformations of several representative efficient TSLP frameworks can be expressed as compositions of these primitives.
