Abstract

Gentry, Sahai and Waters constructed the first identity-based fully homomorphic encryption schemes from identity-based encryption schemes in CRYPTO 2013. In this work, we focus on improving their IBFHE schemes, using Micciancio and Peikert’s novel and powerful trapdoor in conjunction with Alperin-Sheriff and Peikert’s simple and tight noise analysis technique when performing homomorphic evaluation.
