We propose a leakage-resilient unbounded extensible set delegation encryption scheme, which tolerates amount of bounded key leakage and supports unbounded delegation depth. Our scheme provides the tolerance of key continual leakage that can capture both memory leakage and continual leakage, which has appealing applications since there are multiple secret keys per identity set and also can periodically update and refresh the secret key. We construct the scheme in composite order bilinear groups and prove the security with dual system encryption methodology.
