Title On group-homomorphic encryption

Abstract

Group homomorphic encryption represents one of the most important building blocks in modern cryptography. It forms the basis of widely-used, more sophisticated primitives, such as CCA2-secure encryption or secure multiparty computation.

In this talk, we present various recent results on group-homomorphic encryption schemes like a security characterization in terms of an algebraic problem, a complete characterization both in terms of security and design of a specific sub-class called shift-type, and

the general impossibility of group homomorphic encryption in the presence of quantum adversaries. Furthermore, we point out some connections to fully-homomorphic encryption schemes and state several research directions. slides
