Abstract

Delivery secret information in a short message with SMS is not secure. This is case study research on UPT Pendidikan XII Kemang Bogor which is part of government intitution on education and culture of republic Indonesia which has responsibility for supervision business processes in public schools, one of the existing business processes in UPT are sending confidential information such as schedule unannounced inspections for supervisor ln public school without any security on the SMS, so easy to read by anyone. So, we need a security application in order for the SMS messages sent can be kept confidential. One way to secure the message is to use cryptographic, this technique wil encode message before sent (encrypt) and people who will receive message have to open message with key (decode). The algorithm used in this application is AES Rijndael algorithm 128. This application using system development life cycle Waterfall and using SMS Gateway features. Applications built using Java programming language and uses a MySQL database. Conclusion for this research is implementation AES Rijndael 128 algorithmto SMS security application can protect confidential information that is sent by operator to supervisor Education at UPT Kemang Bogor XIIwithout change message.

Abstract

Document exam for midterm and final exam is one of the very important document because it is used by lecturers to evaluate the lecture material for Teaching and Learning Activities. ICT Laboratory Integrated Budi Luhur University as one of the operator of the test lab at the University of Budi Luhur who has responsibility for securing documents exams during the process of mid term and final exam, so in practice there is requiring an application to security documents such as Cryptography Web Based Application using algorithms AES-128 on Lab ICT Integrated Budi Luhur University. Method that is used to develop this application is using Waterfall model, this application used PHP with MySQL database. The research objective is to implement the algorithm AES-128 to encrypt and decrypt files exam on Lab ICT Integrated Budi Luhur University, securing document exam file that can not be read by anyone other than the owner of the file and the person who has access to the file. The conclusion of this study prove that the method algorithm AES-128 algorithm is excellent in secure files, as well as by the application of safeguards files, documents exams more awake, and confidential and the decryption process, the results of the file content decryption did not change from the original file.
