Abstract
Fine-grained access control become a research spotlight in the scenario of the smart home with Internet-of-Things (IoTs). However, most of the existing works could only realize ciphertext outsourcing with an unchangeable encryption key in the cloud. That is because the trivial solution needs great communication overhead. To overcome this challenge, we propose an updatable encryption scheme named SM9-UE for the IoT smart home scenario. The scheme in constructed on the basis of SM9, a Chinese official cryptography standard. SM9-UE realizes secure and lightweight ciphertext updating through using the token generated by the data owner, which is information independent with the plaintext. We give the formal security definition and prove it to be IND-UPD secure. Theoretical comparisons demonstrate that our scheme is efficient in terms of computation and storage. Experimental results also indicate that SM9-UE can be practically applied to IoT smart home.
