Chat Message Security Enhancement on WLAN Network Using Hill Cipher Method

摘要

Security is very important for the owner of the information, therefore the owner information must have good security so that the information they have cannot be owned by unwanted people. Information exchange can happen anywhere with various media exchanges. Exchange information using various networks. Among LAN networks, WLANs, WAN and so on. In exchange for WLAN networks, WLAN networks have many disadvantages and lack both in speed of delivery data and data security. In exchanging data using WLAN, Information thieves can infiltrate IP addresses on the WLAN network can steal and have the same access as WLAN network users another. Therefore we need a technique that can securely exchange information (chat messages) on the WLAN network. The author makes a system that can be used to secure message exchange information chat on WLAN networks with cryptographic techniques namely Security Of Chat Message On WLAN Network By Using Hill Chiper Method With this system the security of chat messages can be better.
