A Lightweight Blockchain-based Public-Key Authenticated Encryption with Multi-Keyword Search for Cloud Computing

چکیده

Cloud computing can provide users with sufficient resources, storage, and bandwidth to meet their needs. Data security privacy protection are among the new threats faced by users. Searchable encryption is combination of search technology technology. upload user’s data cloud server after special encryption, realize function retrieving according keywords. Comparatively symmetric searchable (SSE), public key (PEKS) simplifies management greatly. However, most existing authenticated keyword (PAEKS) schemes based bilinear pairing, making them computationally expensive. Apart from this, complex retrieval requirements integrity results had not been considered. To address these problems, we propose a blockchain-based PAEKS supporting multi-keyword queries verification. In addition, proofs for scheme under decisional oracle Diffie-Hellman (DODH) assumption. This that requires less storage computational power than other same kind.

Public Key Encryption with Keyword Search Revisited

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 security of the original data. In this paper, we address three important issues of a PEKS scheme, “refreshing keywords”, “removing secure channel”, and “processing multiple keywords”, which have not been c...

Public Key Encryption with Keyword Search

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 test whether the email contains the keyword “urgent” so that it could route the email accordingly. Alice, on the other hand does not wish to give the gateway the ability to decrypt all her messages. W...

Public-Key Encryption with Registered Keyword Search

Public-key Encryption with Keyword Search (PEKS) enables a server to test whether a tag from a sender and a trapdoor from a receiver contain the same keyword. In this paper, we highlight some potential security concern, i.e. a curious server is able to answer whether any selected keyword is corresponding to a given trapdoor or not (called an offline keyword guessing attack). The existing semant...

Lattice-Based Public Key Encryption with Keyword Search

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 be searched by a receiver. The receiver can retrieve the encrypted files containing specific keywords by providing the corresponding trapdoors of these keywords to the server. Despite their merits, ...
