Tools over bilinear groups for modular design of cryptographic tasks

Abstract

Modular construction is a design paradigm that combines smaller and more general building blocks for larger and more specific cryptographic tasks. It is often used in theoretical works to show feasibility of the tasks and efficient instantiations are considered separately. Some cryptographic tasks find efficient solutions dedicated for their own purposes, yet efficient modular designs are of value as they can be a reasonable alternative for comparison and offer more comprehensible security proofs. © 2012 Springer-Verlag.
