Problem

● Sensitive data is placed every day in the

cloud

● The cloud is an unreliable environment:

○ Confidentiality must be

guaranteed against service

providers and external attackers

○ Necessity to protect data during

communications and storage

● Encrypting is an overkilling solution.

Encrypted databases have trouble

executing queries over ciphered data

Solution

● encryptedDB is an encrypted database

for the cloud that supports the same

functionality as a non encrypted

database

● It can protect information related to:

○ Personal data

○ Health data

○ Financial data

○ Business and companies

○ Other sensitive data

Main features

● Client-side encryption:

○ Encryption is transparent to users and applications

○ The cloud never has access to clear data

● Extended functionality:

○ Efficient queries over encrypted database fields regardless of

underlying data types

○ Improved scalability by combining relational and non relational

databases
