Unidirectional Key Update in Updatable Encryption, Revisited
<|reference_start|>Unidirectional Key Update in Updatable Encryption, Revisited: In this paper we construct a new efficient updatable encryption (UE) scheme based on FrodoPKE learning with errors key encapsulation. We analyse the security of the proposed scheme in the backward-leak uni-directional setting within the rand-ind-eu-cpa model. Since the underlying computationally hard problem here is LWE, the scheme is secure against both classical and quantum attacks.<|reference_end|>
