PROJECT TITLE :

CypherDB: A Novel Architecture for Outsourcing Secure Database Processing - 2018

ABSTRACT:

CypherDB addresses the problem of protecting the confidentiality of database stored externally in an exceedingly cloud and enabling efficient computation over it to thwart any curious-however-honest cloud computing service supplier. It works by encrypting the whole outsourced database and executing queries over the encrypted information using our novel CypherDB secure processor architecture. To optimize computational potency, our proposed processor design provides tightly-coupled datapaths that avoid information leakage during database access and query execution. Our simulation employing a well-known database benchmark TPC-H over a business grade Database Management System (SQLite) demonstrates that our proposed design incurs a median of about 10 % overhead compared with the same set of operations while not secure database processing.
