Abstract
The objective of this research was to suggest some simple solution to increase database manipulation security. Based on advantage of Homomorphic encryption, user’s data in database is always encrypted by Homomorphic encryption algorithm such as Paillier. User’s data is manipulated or processed on many times such as addition, subtraction, multiplication and division. By the advantage of Homomorphic encryption algorithm, user’s data were no need to decrypt while it was manipulated therefore secrecy of data was still reserved. Unfortunately, Paillier’s Homomorphic encryption is normally coverage only addition and multiplication mathematical data operation. This paper suggests simple technique to enhance Pailler’s encryption algorithm to perform data operation as well in subtraction and division operation. Evaluation in suggested data base manipulation, DSM-PHE, indicates that its operation tasks was five operation times more than ordinary data base manipulation operation tasks, without any encryption. Therefore DSM-PHE should be especially used in more sensitive data.
Highlights
In database manipulation, there are many problems in secrecy or privacy of kept data in database engine
This research suggested a solution to conceal user‘s data all the time while they are kept in database engine and even on data processing by anyone that performs a task by using user‘s data
-get data record ID from Doi: sending request. -retrieve database engine for encrypted data record belong to a given specific record ID
Summary
There are many problems in secrecy or privacy of kept data in database engine. Inquired data for data manipulation event have to be revealed especially when data processing is on performing. This disclosure user‘s data wasobserved or even copied by data manipulation officer and/or others. This research suggested a solution to conceal user‘s data all the time while they are kept in database engine and even on data processing by anyone that performs a task by using user‘s data. Paillier‘s Homomorphic encryption algorithm is used to solve this problem. Paillier‘s encryption is an algorithm of encryption that possesses Homomorphic property. The latter covers addition and multiplication operation. This paper presented a simple technique to enhance Paillier‘s encryption to handle subtraction and division operation
