Block Chaining

Generally, the database access of a website lies in the user login. When the login data is not accompanied by security techniques, it is very easily accessible by other parties. One effort that can be done to solve the problem is to encode the login data of website users based on cryptographic technique algorithm. Triangle Chain Cipher (TCC) is one of the classic cryptographic algorithms that encode data doubly and generate keys randomly along the plain. The process of encryption and decryption are interdependent to be one of the advantages of this algorithm. This algorithm will be more effective when combined with the Cipher Block Chaining (CBC) operation mode that is widely used in modern cryptographic algorithms today. The feedback mechanism between the blocks in this mode of operation is the operating advantage. This study describes how to combine the mode of operation of block chaining cipher with triangle chain cipher algorithm so that cipher data login website generated more random and difficult to find its original meaning.

Abstract Databases provide an efficient way to store, retrieve and analyze data. Oracle relational database is one of the most popular database management systems that is widely used in a different variety of industries and businesses. Therefore, it is important to guarantee that the database access and data manipulation is optimized for reducing database system response time. This paper intends to analyze the performance and the main optimization techniques (Forall, Returning, and Bulk Collect) that can be adopted for Oracle Relational Databases. The results have shown that the adoption of Forall and Bulk Collect approaches bring significant benefits in terms of execution time. Furthermore, the growth rate of the average execution time is lower for Bulk Collect than Forall. However, adoption of Returning approach doesn’t bring significant statistical benefits.
