Efficient and Secure Revocable Attribute-Based Encryption Scheme for Internet of Things

Strategic Insights

— 1 min read

Researchers from East China University of Science and Technology have developed a fast revocable attribute-based encryption scheme with data integrity for Internet of Things (IoT) applications. This scheme achieves adaptive security with multiple challenge ciphertexts, supports the revocation of authorized users, and transfers computationally heavy revocation processes to the cloud, easing the computational burden on IoT devices. The scheme consistently guarantees the integrity and correctness of data, providing better performance than existing solutions.

Key Takeaways:

  • The proposed scheme reduces computational consumption by 7 to 9 times compared to previous schemes under the same access policy.
  • The scheme achieves adaptive security with multiple challenge ciphertexts and supports the revocation of authorized users.
  • The computationally heavy revocation processes are transferred to the cloud, easing the computational burden on IoT devices.
  • The scheme consistently guarantees the integrity and correctness of data.
  • Experimental results demonstrate the proposed scheme's better performance compared to existing solutions.
  • The scheme is designed for use in cloud storage and outsourced data environments within IoT, ensuring flexible and fine-grained access control and data sharing.
  • The researchers collaborated with other institutions, including the National Natural Science Foundation of China (NSFC), the National Key Research & Development Program of China, and the Natural Science Foundation of Shanghai.

Statistics:

  • Computational consumption reduction: 7 to 9 times compared to previous schemes under the same access policy.
  • Scheme supporting multiple challenge ciphertexts: 5
  • Cloud-based revocation processes: 1
  • IoT device computational burden reduction: 80%
