We provide a new frame in this paper, the ciphertext-policy attribute-based encryption with functional keyword search (ABFKS) in fog computing. The ABFKS achieves functional keyword search and peer-pe...
Public key Encryption with Keyword Search (PEKS) aims in mitigating the impacts of data privacy versus utilization dilemma by allowing any user in the system to send encrypted files to the server to b...
Cloud computing is very popular for its computing and storage capacity at lower cost. More and more data are being moved to the cloud to reduce storage cost. On the other hand, since the cloud is not ...
Outsourcing data storage to the cloud securely and retrieving the remote data in an efficient way is a very significant research topic, with high relevance to secure cloud deployment. With the ever gr...
Recently, a new framework, called secure server-designation public key encryption with keyword search (SPEKS), was introduced to improve the security of dPEKS (which suffers from the on-line keyword...
Keyword search on encrypted data enables one to search keyword ciphertexts without compromising keyword security. We further investigate this problem and propose a novel variant, dubbed certificatel...
Cloud data owners encrypt their documents before outsourcing to provide their privacy. They could determine a search control policy and delegate the ability of search token generation to the users who...
It is common nowadays for data owners to outsource their data to the cloud. Since the cloud cannot be fully trusted, the outsourced data should be encrypted. This however brings a range of problems, s...
It is widely acknowledged that the keyword search performance and the privacy of keywords are equally important for keyword searchable ciphertexts. To our knowledge, no public-key-encryption-based wor...
With tremendous interests having been attracted, public-key encryption with keyword search (PEKS) achieves the searchability of encrypted keywords without sharing a secret between the sender and the r...
Recently, Shen, Shi, and Waters introduced the notion of predicate privacy, i.e., the property that t(x) reveals no information about the encoded predicate p, and proposed a scheme that achieves predi...
As Cloud Computing becomes prevalent, more and more sensitive information are being centralized into the cloud. For the protection of data privacy, sensitive data usually have to be encrypted before...
In this paper, we introduce a notion of Oblivious Keyword Search (OKS). Let W be the set of possible keywords. In the commit phase, a database supplier T commits n data. In each transfer subphase, a...
We study the problem of searching on data that is encrypted using a public key system. Consider user Bob who sends email to user Alice encrypted under Alice's public key. An email gateway wants to t...
The public key encryption with keyword search (PEKS) scheme recently proposed by Boneh, Di Crescenzo, Ostrovsky, and Persiano enables one to search encrypted keywords without compromising the securi...
