Ciphertext-policy hierarchical attribute-based encryption with short ciphertexts

•We model access control of sensitive data between multiple organizations.•We propose Ciphertext-Policy Hierarchical Attribute-Based Encryption (CP-HABE).•CP-HABE is equipped with key delegation for users of different organizations.•The first CP-HABE scheme is presented with short ciphertexts.•Our scheme is proven secure in standard model under static assumptions.
