Abstract:
Database security has become a vital
issue in modern Web applications. Critical
business data in databases is an evident target
for attack. Database encryption has become a
critical technique in the security mechanisms of
database. This paper proposed a secure
framework for semi-trusted database in which
data is encrypted in a mixed form using many
keys owned by different parties. That can provide
security and cost-effective by reducing the server
tasks required to perform encrypt and decrypt
operations. The framework aims to ensure the
requirements of secure semi-trusted database
include; Data Confidentiality and User Data
Privacy and Data Integrity. The proposed
framework is strengthening the protection of
sensitive data even if the database server is
attacked at multiple points from the inside or
outside.
