Generic and Efficient Constructions of Attribute-Based Encryption with Verifiable Outsourced Decryption
Attribute-based encryption (ABE) provides a mechanism for complex access control over encrypted data. However in most ABE systems, the ciphertext size and the decryption overhead, which grow with the complexity of the access policy, are becoming critical barriers in applications running on resource-limited devices. Outsourcing decryption of ABE ciphertexts to a powerful third party is […]
