ON INFORMATION SECURITY USING A HYBRID CRYPTOGRAPHIC MODEL


Developing a good database system and providing security control for the database has always been a big challenge. Encryption technique has previously been proposed to provide users with confidentiality in terms of outsource storage. However, a number of these encryption algorithms are weak, enabling adversaries to compromise data simply by compromising an algorithm. A response to this challenge was made by developing a new hybrid encryption model using features of Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES). A comparison was made on our new hybrid encryption model with existing encryption models. The new model improved the security of information stored in a database. The results demonstrated that the new model offers a highly secured approach that provides users and organizations with data confidentiality and integrity. It also provided acceptable overhead performance and supports query processing.
