A secure attribute based keyword search scheme against keyword guessing attack

2016 8th International Symposium on Telecommunications (IST), 2016
To provide the privacy of the users who receive some computing services from the cloud, the users must encrypt their documents before outsourcing them to the cloud. Computation on outsourced encrypted data in the cloud rises some complexity to the system specially in the case when an entity would like to find some documents related to a special keyword.

Proxy re-encryption conjunctive keyword search against keyword guessing attack

2013 Computing, Communications and IT Applications Conference (ComComAp), 2013
Public key encryption with keyword search enables users to retrieve keywords from encrypted data, which can protect data confidentiality without losing the search operability. However, it is also vulnerable to keyword guessing attacks. In this paper, we propose a conjunctive keywords searchable encryption with designated tester (dPECK) to prevent the ...

Conjunctive Keywords Searchable Encryption Scheme Against Inside Keywords Guessing Attack from Lattice

2020
Public-key encryption with conjunctive keywords search (PECKS) is an extension of public-key encryption with keywords search (PEKS), which can realize the efficient search of the encrypted data stored in the cloud server and keep the privacy of these data during the search phase.

Online/offline attribute-based encryption with keyword search against Keyword Guessing Attack

2017 3rd IEEE International Conference on Computer and Communications (ICCC), 2017
With the exposure of security events in cloud storage, encrypting data before uploading has become the most favorable choice for cloud users, which makes search on encrypted data an important issue. Attribute-based encryption with keyword search (ABKS), which achieves data access control and search on encrypted data at the same time, has risen in ...

Keyword search encryption scheme resistant against keyword-guessing attack by the untrusted server

Journal of Shanghai Jiaotong University (Science), 2014
The user data stored in an untrusted server, such as the centralized data center or cloud computing server, may be dangerous of eavesdropping if the data format is a plaintext. However, the general ciphertext is difficult to search and thus limited for practical usage.

Public key encryption with conjunctive keyword search secure against keyword guessing attack from lattices

Transactions on Emerging Telecommunications Technologies, 2018
AbstractPublic key encryption With keyword search (PEKS) enables a cloud server (CS) to get the search trapdoor to identify ciphertext containing the target keyword without decrypting the ciphertext or knowing the target keyword. With the advent of mobile cloud computing, PEKS has ushered in an era of new development opportunities and new challenges ...

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 ...

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

International Journal of Communication Systems, 2018
Summary Designated 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 ...

Hidden policy ciphertext-policy attribute-based encryption with keyword search against keyword guessing attack

Science China Information Sciences, 2016
Attribute-based encryption with keyword search (ABKS) enables data owners to grant their search capabilities to other users by enforcing an access control policy over the outsourced encrypted data. However, existing ABKS schemes cannot guarantee the privacy of the access structures, which may contain some sensitive private information.
