A Leakage-Resilient Spatial Encryption Scheme

A scheme is said leakage resilient if it remains secure even when an adversary is able to learn partial information about some secret values used throughout the lifetime of the system. This recent area appeared because of the need to develop schemes that resist to sidechannel attacks, such as power-consumption, fault or time analyses. Today, there exist a few encryption schemes that implement this security model, notably a leakage-resilient identity-based encryption scheme (IBE): a public-key encryption scheme where the public keys are the identities, and a master key allows the generation of a secret key for each identity.
