Abstract

In this era, technology is increasingly advanced and rapid, where data confidentiality is one of the things that is very important for a company. Employee data is data that is very important for the company. So it needs a system that can secure a database of employees from various types of hecker attacks or eavesdroppers who can steal and damage data. Cryptography is a science based on mathematical techniques that deal with information security such as data confidentiality. Triple DES algorithm is a development of DES algorithm, the algorithm used is the same, only in Triple DES algorithm, the encryption and decryption process is done 3 times. Triple DES also has three different keys. The three keys used can be mutually independent (K1 ? K2 ? K3) or only two keys are mutually independent and one other key is the same as the first key (K1 ? K2 and K3 = K1). This algorithm can generate encryption that cannot be read or understood by humans and results in the exact decryption of the initial plaintext input.

Abstract

Internet network is one of the most important needs in a company to access online in uploading or downloading a file. Where almost all companies already use computers and use the network as a tool to facilitate work. The problem that often occurs in the use of internet networks is that the speed is unstable, because users or users of the same network are more than one person, causing internet splits to split and not focus on one user. Mikrotik is a company that stands and makes products such as Routers, Switches, Antennas. By using a proxy router, the author found a solution to solve the problem by doing a bandweed mechanism with the aim of preventing the monopoly of bandwidth usage, so that all users or users in one network can get their bandwidth in a fair manner. Bandwidth management is a method used to meet these needs. And to do the settings, the author uses the Winbox application and also the queue function to do the implementation of the proxy router. The author uses the ip address of each computer that is connected in one network, to be used as data and then processed in the Winbox application, for bandwidth management.
