"In this paper, the authors discuss an emerging concept of decoy-based information security, or security without computational assumptions. In particular, they show how this concept can be implemented to provide security against (passive) computationally unbounded adversary in some public-key encryption protocols. In the world of symmetric cryptography, decoy-based security finds a wide range of applications, notably to secure delegation of computation to another party. They single out the scenario where a computationally limited party wants to send an encrypted message to a computationally superior party using the RSA protocol, thereby providing another kind of application of decoy ideas in a public-key setting."
