Abstract

We present a general encryption model with partial order delegation ability, which is a generalized extension for hierarchical identity-based encryption, broadcast encryption and delegatable functional encryption, etc. We also construct a concrete anonymous encryption scheme with constant-size ciphertext which may perform key derivation with partial-order subset delegation functionality, and prove its security in the standard model including semantic security, anonymity, and delegation indistinguishability. We give some practical application scenarios and deployments for our scheme.
