Constructing designated server public key encryption with keyword search schemes withstanding keyword guessing attacks

International Journal of Communication Systems, 2018
SummaryDesignated server public key encryption with keyword search (dPEKS) removes the secure channel requirement in public key encryption with keyword search (PEKS). With the dPEKS mechanism, a user is able to delegate the search tasks on the ciphertexts sent to him/her to a designated storage server without leaking the corresponding plaintexts ...

Off-Line Keyword Guessing Attacks on Recent Keyword Search Schemes over Encrypted Data

2006
A keyword search scheme over encrypted documents allows for remote keyword search of documents by a user in possession of a trapdoor (secret key). A data supplier first uploads encrypted documents on a storage system, and then a user of the storage system searches documents containing keywords while insider (such as administrators of the storage system)

Designated-Senders Public-Key Searchable Encryption Secure against Keyword Guessing Attacks

2017 Fifth International Symposium on Computing and Networking (CANDAR), 2017
To achieve keyword search in secure cloud storage, a public-key encryption with keyword search (PEKS) has been proposed. However, the PEKS is inherently vulnerable to the Keyword Guessing Attack (KGA): Using the public key, anyone including the server can compute the ciphertext of any keyword.

Off-Line Keyword Guessing Attacks on Recent Public Key Encryption with Keyword Search Schemes

2008
The Public Key Encryption with Keyword Search Scheme (PEKS) was first proposed by Boneh et al. in 2004. This scheme solves the problem of searching on data that is encrypted using a public key setting. Recently, Baek et al. proposed a Secure Channel Free Public Key Encryption with Keyword Search (SCF-PEKS) scheme that removes the secure channel for ...

Cloud-Assisted Privacy Protection for Data Retrieval Against Keyword Guessing Attacks

2020
Machine learning is more closely linked to data privacy and has obtained rapid development in recent years. As for data privacy, searchable encryption (SE) is widely used as a ciphertext search technology, protecting the privacy of users. However, existing schemes usually support single keyword search, so the remote cloud server (CS) may return some ...

Efficient searchable public key encryption against keyword guessing attacks for cloud-based EMR systems

Cluster Computing, 2018
Due to the tremendous benefits of cloud computing, an increasing number of health care providers tend to deploy the electronic medical record (EMR) storages and application services into cloud. To protect patients’ privacy, sensitive EMRs have to be encrypted before being uploaded to cloud.
