This report has two goals. First, we review guidelines for using the CryptDB system [PRZB11, Pop14] se- curely by the administrators of database applications. These guidelines were already described in [PRZB11] and elaborated on in [Pop14], but in light of some recent work [NKW15] that applied these guidelines in-. 22 Nov 2013 quite open. In case the proxy and the infrastructure are untrusted, CryptDB can capture the application's access policy. This is where application developers have poser to annotate database schema in CryptDB to specify which principal has access to a certain subset of data items. CryptDB provides three ABSTRACT. Online applications are vulnerable to theft of sensitive information because adversaries can exploit software bugs to gain access to private data, and because curious or malicious administrators may capture and leak data. CryptDB is a system that provides practical and provable confidentiality in the face of ABSTRACT. CryptDB is a DBMS that provides provable and practical privacy in the face of a compromised database server or curious database administrators. CryptDB works by executing SQL queries over encrypted data. At its core are three novel ideas: an SQL-aware en- cryption strategy that maps SQL operations to Google recently deployed a system for performing SQL-like queries over an encrypted database following (and giving credit to) the CryptDB design. Their service uses the encryption building blocks from CryptDB (RND, DET, HOM, and SEARCH), rewrites queries and annotates the schema as in CryptDB. Lincoln Labs In this paper, CryptDB is revisited from cryptographic point of view. First of all, CryptDB is described in more details for ease of understanding and then the drawbacks of CryptDB are highlighted from security and efficiency points of view. 145.pdf, ”The NIST Definition of Cloud Computing, National.
