Attribute-Based Encryption With Efficient Verifiable Outsourced Decryption
IEEE Transactions on Information Forensics and Security, 2015 Attribute-based encryption (ABE) with outsourced decryption not only enables fine-grained sharing of encrypted data, but also overcomes the efficiency drawback (in terms of ciphertext size and decryption cost) of the standard ABE schemes. In particular, an ABE scheme with outsourced decryption allows a third party (e.g., a cloud server) to transform an

Attribute-Based Encryption With Verifiable Outsourced Decryption
IEEE Transactions on Information Forensics and Security, 2013 Attribute-based encryption (ABE) is a public-key-based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes. A promising application of ABE is flexible access control of encrypted data stored in the cloud, using access polices and ascribed attributes associated with private keys and ciphertexts.

Generic Approach to Outsource the Decryption of Attribute-Based Encryption in Cloud Computing [PDF]
IEEE Access, 2019 The notion of attribute-based encryption with outsourced decryption (OD-ABE) was proposed by Green, Hohenberger, and Waters. In OD-ABE, the ABE ciphertext is converted to a partially-decrypted ciphertext that has a shorter bit length and a faster ...
