Tinjauan Aspek Keamanan Data pada LAN dengan menggunakan Metode Enkripsi Algoritma RSA dan IDEA (Studi Kasus Wireless LAN)

The Information Technology grow up very vast, that is also make the way to get

information more variously. One way to get information is from computer network

Computer network can be thought as a group of some computers that connecting one

another and each computer that connected in the network can control themselves just like

shutdown the computer. According to the transmission medium, the computer network

can be group as Wire LAN and Wireless LAN. Wire LAN is a network that use cable for

the connecting medium, and Wireless LAN is a network that use noncable or

electromagnetic wave for the connecting medium. And just like the Wire LAN, the

Wireles LAN also have some serious handling in data security. One of the method that

can be used is data encryption. Data encryption is a process to coding data before sending

it. Sof if there are some hackers that catch the data on the way to the destination, it will

be more difficult for them to decoding the data.
