Limitations of Information-theoretic Incompressible Encodings

Petr Sedláček

Abstract

In this note we study the limitations of incompressible encodings with information-theoretic security. We demonstrate a flaw in the existing proof of the impossibility of constructing incompressible encodings information-theoretically. Our main contribution is a full proof of impossibility of existence of non-trivial information-theoretically secure incompressible encoding schemes.
