Title
ABSS: An Attribute-based Sanitizable Signature for Integrity of Outsourced Database with Public Cloud
Abstract
Database outsourcing is an important application of cloud computing, and security is one of the most critical concerns in adopting this application model, such as data privacy, query privacy, etc. Data integrity is another essential requirement for outsourced database system. When the database is outsourced to public cloud, the situation is more complex as different users may modify the data and these users may hold different privileges for different parts of the database. Furthermore, as the cloud is in charge of the management of the database, users have to rely on the cloud to guarantee data integrity. We propose ABSS to protect the integrity of outsourced database which supports fine-grained modification policy. ABSS utilizes an attribute based sanitizable signature scheme, which combining the ingredients of attribute based encryption and sanitizable signature. ABSS enables the database owner to deploy fine-grained policy of database modification and can detect illegal modifications without trusting the cloud. We also discuss the security properties and performance of ABSS to show its practicability.
