Efficient Database Encryption Scheme for Database-as-a-Service Environment

A Structure Preserving Database Encryption Scheme

A new simple and efficient database encryption scheme is presented. The new scheme enables encrypting the entire content of the database without changing its structure. In addition, the scheme suggests how to convert the conventional database index to a secure index on the encrypted database so that the time complexity of all queries is maintained. No one with access to the encrypted database c...

Implementing a Similarity Searchable Encryption Scheme for Cloud Database Usage

A two-phase encryption scheme for enhancing database security

In this article, we propose a two-phase encryption algorithm for data base systems. The system, a record-oriented cryptosystem, allows the encryption and decryption of fields within a record by means of writing and reading subkeys of fields. In addition, we develop two algorithms for cryptographic relational algebra in data base systems. Two simple methods of solving the key management problem ...

Towards Database Virtualization for Database as a Service

Advances in operating system and storage-level virtualization technologies have enabled the effective consolidation of heterogeneous applications in a shared cloud infrastructure. Novel research challenges arising from this new shared environment include load balancing, workload estimation, resource isolation, machine replication, live migration, and an emergent need of automation to handle lar...

Separating indexes from data: a distributed scheme for secure database outsourcing

Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...
