1.2 PROBLEM IDENTIFICATION

In this research the problem identification are: 1. How to create a service in this case web service to interface see, edit and verify the data in private network in this case skpd – malang information system which used intranet for their security so that only people that involved in their institution can access the databases. 2. How to implemented digital signature inside the web service instead to verify the data from manipulation data. 3. How to Create and use two key pair to lock and open the encryption, private to lock the data put in server side and public key to decrypt the data put in client and also the opposite. This key pair used to take data from intranet of SKPD malang.

1.3 PROBLEM LIMITATION

In this research Problem limitations are: 1. Digital signature only focus on MD5 and RSA algorithm to encrypt and produce hashing code in system 2. RSA algorithm used certified as public key .cer in this case used certified X509 and PKCS12 to produce public key. 3. The data which encrypted is the data that contains in the database at archives finance system of SKPD malang. 20

1.4 PURPOSE OF RESEARCH

The purpose of this project is to create the web security service by using web service and RSA digital signature with MD5 algorithm.

1.5 BENEFIT OF RESEARCH 1. ACCADEMIC PARTS

- To help another researcher as reference to implement and to do the same research with another method in security to protect data. 2. Finance archives information system RKA-SKPD Rencana Kerja Dan Anggaran - Satuan Kerja Perangkat Daerah malang city - For the object itself will help to minimize the risk of system hacked. - Establish cooperation between the Agencies and work education for writer, so that could be used as reference to prepare workforce of more advanced and competitive. 3. THE WRITER - For writer will help to give knowledge in digital signature, web service and cryptography. - To meet one of the requirements of graduation degree S1, Informatics Engineering, Faculty of Science and Technology State Islamic University Syarif Hidayatullah Jakarta. - To introduce corporate overview required of students who will enter the world of work according to their field and as a work experience. 21
