Semantic Searchable Encryption Scheme Based on Lattice in Quantum-Era
When data is outsourced to a remote storage server, searchable encryption plays an important role to protect data privacy while allowing users to retrieve data in the massive ciphertext. As far as we know, most of the existing searchable encryption schemes work based on the bilinear map. These schemes may not be secure in the quantum age. Both discrete logarithms and factorization can be solved...
متن کاملPublic Key Encryption with Searchable Keywords Based on Jacobi Symbols
Vishal Saraswat (CRRao AIMSCS) Searchable Encryption APHRDI, 22/09/16 10 / 46 Vishal Saraswat Some other projects Abstract Public-key encryption with keyword search (PEKS) schemes are useful to delegate searching capabilities on encrypted data to a third party, who does not hold the entire secret key, but only an appropriate token which allows searching operations but preserves data privacy. PE...
متن کاملA Leakage-Abuse Attack Against Multi-User Searchable Encryption
Searchable Encryption (SE) allows a user to upload data to the cloud and to search it in a remote fashion while preserving the privacy of both the data and the queries. Recent research results describe attacks on SE schemes using the access pattern, denoting the ids of documents matching search queries, which most SE schemes reveal during query processing. However SE schemes usually leak more t...
متن کاملSearchable Keyword-Based Encryption
To solve the problem of searching on encrypted data, many keyword search schemes have been proposed in recent years. The goal of such schemes is to enable a user to give an untrusted storage server the ability only to test whether an encrypted document contains a few keywords without learning anything else about the document. In this paper, we are concerned with decrypting the searched results ...
متن کاملA Searchable Symmetric Encryption Scheme using BlockChain
At present, the cloud storage used in searchable symmetric encryption schemes (SSE) is provided in a private way, which cannot be seen as a true cloud. Moreover, the cloud server is thought to be credible, because it always returns the search result to the user, even they are not correct. In order to really resist this malicious adversary and accelerate the usage of the data, it is necessary to...
