Abstract: Modern cryptography enables secure computation on private data, offering several societal benefits. For example, it empowers mutually distrustful individuals to jointly analyze their datasets while ensuring privacy. Similarly, it enables individuals to verify the integrity of private computations without compromising confidentiality. However, despite significant advancements, cryptography remains resource-intensive and has yet to see widespread adoption among end-users.My research addresses the following question: can end-users with limited resources still benefit from cryptographic advancements by outsourcing cryptographic computations to cloud servers? Moreover, can the security of such outsourced computations be guaranteed, even in the presence of untrusted servers? While cryptography can be used to ensure security when delegating “any” computation, it often introduces significant computational overheads.In this talk, I will explore whether “cryptographic” computations themselves can be securely delegated without requiring an additional, computationally expensive layer of cryptography. In other words, can we achieve efficient delegation - minimizing the burden on end-users while ensuring that it remains cost-effective? I will present new techniques that provide positive answers to these questions.
