Abstract :
In order to prevent the attack and discovery of sensitive data, a model is presented to protect the confidentiality of data even when the attackers have access to all data from the server: using systems that perform queries and inserts on encrypted data without the decryption key. The model set is applied in a real scenario: a distributed system hosted by Google (Encrypted BigQuery), which includes the use of encryption in data stored in non-relational databases for massive data processing. As a result, it is shown that this system supports a variety of applications with low overhead.
