Abstract

Single Sign On (SSO) merupakan model autentikasi independen yang diimplementasikan Universitas Ubudiyah Indonesia (UUI) menggunakan Message-Digest Algorithm 5 (MD5) dan web service NuSOAP berbasis bahasa pemograman PHP. Sistem ini berjalan pada protokol Hypertext Transfer Protocol (HTTP). Faktanya penggunaan protokol HTTP ini sangat rentan terhadap berbagai jenis serangan karena data dikirim dalam bentuk plaintext tanpa ada proses enkripsi dan penerapan algoritma MD5 pada autentikasi login juga rentan terhadap serangan dictionary attacks dan rainbow tables. Disisi lain, Penggunaan web service NuSOAP juga menciptakan celah keamanan karena pengiriman dan penerimaan payload tidak dienkripsi. Saat ini diketahui sudah ada beberapa metode yang dapat digunakan untuk meningkatkan pengamanan kerentanan tersebut diantaranya yaitu menggunakan Hypertext Transfer Protocol Secure (HTTPS), Secure Hypertext Transfer Protocol (SHTTP) dan Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA). Namun beberapa hasil penelitian terkait memperlihatkan masih terdapat beberapa kelemahan dari penggunaan HTTPS, SHTTP dan CAPTCHA. Penelitian ini mengusulkan penggunaan algoritma Advanced Encryption Standard (AES) dengan pembangkit kunci dinamis dan metode One-Time Password (OTP) berbasis sinkronisasi waktu dengan kombinasi salt untuk meningkatkan keamanan pada autentikasi SSO UUI. Hasil pengujian menunjukkan penerapan algoritma AES dan OTP  dapat mengamankan proses autentikasi SSO  dari serangan dictionary attack dan rainbow table.

Abstract

Communication problems during emergency situations caused by diverse natural phenomenon, especially earthquake, often occurred in Banda Aceh. Thus, this paper purposes to propose a sophisticated network infrastructure for an effective communication in time of emergency phase. Considering the needs for better communication that can lead to efficient responses in disaster emergency, we try to present a concept of Wireless Mesh Network (WMN) as one of the most effective communication network solutions for today that can perform well in crisis phases. The proposed concept in this paper refers to some existing literatures to develop a reliable communication network that will perform better, especially in time of emergency and other chaotic situations caused by natural phenomenon. This paper draws attention to the existence of a sophisticated network infrastructure in Banda Aceh as it is one of the most prone areas to disasters in Aceh, especially earthquake and tsunami. This paper also urges all stakeholders, like local government, communication providers and other related parties to take this communication solution into consideration thus the communication problems during an emergency phase can be minimized.Keywords: emergency phase, communication network, WMN

Abstract

Communication problems during emergency situations caused by diverse natural phenomenon, especially earthquake, often occurred in Banda Aceh. This is due to an increase in user traffic on the communication network that made most of the providers overwhelmed. Therefore, the existence of a sophisticated network infrastructure for an effective communication in time of emergency phase must be provided. Considering the needs for better communication that can lead to efficient responses in disaster emergency, we try to present a concept of Wireless Mesh Network (WMN) as one of the most effective communication network solutions for today that can perform well in crisis phases. This concept is expected to help the local government, related parties, and communities in doing various communication needs in time of crisis phase. The idea of this WMN is also expected to be taken into consideration for all providers in building their network infrastructure in the future.Keywords: emergency phase, communication network, WMN.

Abstract

Ancient documents are inheritance that must be preserved. The documents contain historical, scientific, social, religious information, etc. Converting ancient documents into digital image formats is one of ways to preserve the inheritance and can be stored into a computer. However, images of ancientdocuments have many blemishes caused by age, moisture, flood, etc. Therefore, special techniques are needed for those images to be restored and can improve the legibility of the ancient documents’ images. In this study, the image restoration process uses separation of background and foreground/text on histogram equalization such as research conducted by Fitri Arnia in 2008. Through histogram equalizationimages can be seen the distribution of pixels from the intensity of black color "0" to white "1". The distribution of pixels on histogram equalization describes the curves of foreground/text and curves of background. Among the histogram curves, the determination of thresholdvalues can be done so as to clarify the foreground/text and background areas on images of ancient documents. The lowest point between the two curves is the lowest pixel (local minima) which is used as the threshold value. However, the selection of such threshold values in some cases is very difficult to determine because there are still many fluctuations in the curve at the lowest curve. Therefore, this study proposesa histogram smoothing method in the ancient documents’ images to minimize curvature fluctuations and to determine more accurate threshold values. In this research, average filtering method is used for smoothing the histogram image. This filter successfully refines the histogram and makes the image of the restoration or binary image display the value of the ancient document image readability increases.Keywords: HistogramEqualization, Smoothing Histogram, Average Filtering, Thresholding

Abstract

The difficulty of finding a place to park a vehicle has become a prominent issue in the area of Banda Aceh, especially in shopping centers are crowded like Atjeh Shopping Center. Lack of parking facilities in Atjeh shopping center, causing the transfer function of a road into a parking lot, which means reducing the effective width of the road and decrease the capacity of the road. Therefore, in this study designed a smart parking system simulation to be known the workings and functions of this system which can save a parking lot also reduce traffic congestion and is expected to be implemented in a parking lot in the basement Atjeh shopping center.Keywords: Atjeh shopping center, simulation, smart parking, unity-4.

Abstract

Single sign-on (SSO) is a session authentication process that allows a user to login by using user registered identity and password in order to access appropriate applications. The authentication process takes the user in to login for all the applications they have been given rights to and eliminates further prompts when they switch applications during a particular session. Its implementation will provide a reduction of password burden to access many applications for every login process. Ease of access through a single account needs to be addressed carefully to ensure the authentication credentials that are not scattered and known by others. Currently, there are several open source SSO authentication methods available. However, the use of existing authentication methods is still vulnerable to attack, such as Man-In-The-Middle. In this study, SSO authentication algorithm using One-Time Password (OTP) is proposed using a combination of time synchronization and salt value. These combinations are used to verify user session while accessing any application with SSO mechanism. The results show that the proposed OTP algorithm can handle SSO authentication process in good fashion and also protect from Man-In-The-Middle Attack.
