Abstract

Dewasa ini sistem informasi semakin berkembang. Hal ini dapat dilihat dari kemajuan teknologi dalam proses komunikasi yang dapat dilakukan secara jarak jauh dari dua tempat yang berbeda. Perkembangan teknologi telekomunikasi dengan menggunakan komputer menyebabkan mobilitas masyarakat semakin baik karena komunikasi bisa dilakukan tanpa perlu interaksi langsung satu sama lain. Berbagai jenis layanan komunikasi tersedia di internet seperti pengiriman pesan melalui email yang semakin diminati oleh masyarakat. Meningkatnya pemanfaatan layanan e-mail melalui internet menyebabkanpermasalahan juga bermunculan selain permasalahan adanya hacker dan cracker. Hal tersebut sangat memungkinkan pesan yang dikirim dapat disadap dan diubah oleh pihak lain. Salah satu bentuk pencegahan kejahatan di internet adalah dengan menggunakan algoritma kunci publik RSA, yaitu dengan cara mengenkripsi pesan yang akan dikirim menggunakan kunci publik yang telah dibangkitkan oleh pihak pengirim. Cara ini akan memperkuat tingkat keamanan pesan yang dikirim dalam suatu jaringan internet selama kunci privat terjaga kerahasiaannya. Oleh karena itu, algoritma RSA akan diterapkan pada suatu perangkat lunak yang dirancang dan dibuat mengunakan bahasa pemrograman Visual Basic .NET 2008 sebagai sarana untuk meningkatkan keamanan pengiriman pesan.

Abstract

Development of a local area network (LAN) needs a network cable such as UTP twisted pair especially for connecting hardware like personal computer with CCTV. The connection should be on the basis of IP address which is connected with switch, and then the data eventually is sent to server. Generally, in the field, a hardware network has two main connection; first, connections to electricity for switching on the software by using an electricity cable which is suitable to the need of electrical capacity; second, connection to UTP twisted network for sending the data to the server. This process can be simplified by using network cable both for sending the data to server and for electrical pathway. Some pairs of network cable which are not used for sending data to server can be occupied to convey electrical wave to switch on and to operate the hardware. In order to use network cable for multiple purposes, it needs electrical configuration such as power of ethernet (PoE). The PoE is a system to utilize the UTP twisted pair cable to transmit unoccupied power for electrical pathway so that it can increase the efficiency of system.
