Deterministic attribute-based encryption
International Journal of High Performance Computing and Networking, 2016Attribute-based encryption enables data owners to share their information by specifying access control policies while outsourcing their encrypted data to the cloud. However, there are no efficient searchable schemes over encrypted data in attribute-based setting.

On Anonymous Attribute Based Encryption
2015Attribute Based Encryption ABE has found enormous scope in data confidentiality and fine-grained access control of shared data stored in public cloud. Classical ABE schemes require attaching the access policy along with the ciphertext, where the access policy describes required attribute values of a receiver.

Distributed Attribute-Based Encryption
2009Ciphertext-Policy Attribute-Based Encryption (CP-ABE) allows to encrypt data under an access policy, specified as a logical combination of attributes. Such ciphertexts can be decrypted by anyone with a set of attributes that fits the policy. In this paper, we introduce the concept of Distributed Attribute-Based Encryption (DABE), where an arbitrary ...

Sahai and Waters first introduced attribute-based encryption (ABE) as an extension of identity-based encryption (IBE), which allows the sender (who generates the ciphertext) to set a policy describing who can decrypt his ciphertext. Note that in an IBE system, a user is associated with a unique identity and can only decrypt the ciphertexts ...

Outsourcing Encryption of Attribute-Based Encryption with MapReduce
2012Attribute-based encryption (ABE) is a promising cryptographic tool for fine-grained access control. However, the computational cost in encryption commonly grows with the complexity of access policy in existing ABE schemes, which becomes a bottleneck limiting its application.

As more sensitive data is shared and stored by third-party sites on the Internet, there will be a need to encrypt data stored at these sites. One drawback of encrypting data is that it can be selectively shared only at a coarse-grained level (i.e., giving another party your private key).

Attribute-Based Symmetric Searchable Encryption
2020Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data while preserving the privacy of both the files and the queries. Unfortunately, majority of the SSE schemes allows users to either decrypt the whole ciphertext or nothing at all.

Attribute-Based Encryption with Personalized Search
2017 IEEE International Symposium on Parallel and Distributed Processing with Applications and 2017 IEEE International Conference on Ubiquitous Computing and Communications (ISPA/IUCC), 2017With the development of cloud computing, more and more enterprises will outsource their sensitive data for sharing in a cloud. However most existing works follow the model of “one size fits all” over encrypted outsourced cloud data, and ignore personalized search intention.

Dual-Policy Attribute Based Encryption
2009We present a new variant of Attribute based encryption (ABE) called Dual-Policy ABE. Basically, it is a conjunctively combined scheme between Key-Policy and Ciphertext-Policy ABE, the two previous available types of ABE. Dual-Policy ABE allows simultaneously two access control mechanisms over encrypted data: one involves policies over objective ...

Conjunctive Broadcast and Attribute-Based Encryption
2009Attribute-based encryption (ABE) system enables an access control mechanism over encrypted data by specifying access policies among private keys and ciphertexts. There are two flavors of ABE, namely key-policy and ciphertext-policy, depending on which of private keys or ciphertexts that access policies are associated with.
