Bridges connecting Encryption Schemes

Mugurel Barcau and Cristian Lupascu and Vicentiu Pasol and George C. Turcas

Abstract

The present work investigates morphisms between encryption schemes, called bridges. By associating an encryption scheme to every such bridge, we define and examine their security. Inspired by the bootstrapping procedure used by Gentry to produce fully homomorphic encryption schemes, we exhibit a general recipe for the construction of bridges and we give various examples. We shall also present an example of a bridge that does not fall in this category.
