DOI: 10.1007/s00500-017-2701-9
Abstract: Prior to outsourcing sensitive data, users need to encrypt the data and outsource the ciphertexts to cloud servers. Therefore, efficient search techniques on encrypted data are required. Attribute-based keyword search (ABKS) is a public key… read more here.

DOI: 10.1155/2021/6656764
Abstract: Attribute-based encryption (ABE) is a good choice for one-to-many communication and fine-grained access control of the encryption data in a cloud environment. Fully homomorphic encryption (FHE) allows cloud servers to make valid operations on encrypted… read more here.
