Hiding the Access Pattern is Not Enough: Exploiting Search Pattern Leakage in Searchable Encryption
[article]
2020
arXiv
pre-print
Preserved Fulltext
Recent Searchable Symmetric Encryption (SSE) schemes enable secure searching over an encrypted database stored in a server while limiting the information leaked to the server. ...
These schemes focus on hiding the access pattern, which refers to the set of documents that match the client's queries. ...
[17] provide a framework to design structured encryption schemes while hiding the access and search pattern. ...
