Abstract— Bandwidth is a carrying capacity of data carriers on a network connection, using units of time in speed. The cost of bandwidth procurement is very expensive and if it is not set up with management and hardware support, good software or brainware will cause huge losses. Therefore, a quality service standard must be created in an Internet Service provider known as Quality of Service (QoS). On a Cisco Router there are several methods of Quality of Service configured in such a way that the bandwidth of an ISP can be restricted and well managed. Traffic Policing and Traffic Shaping are two methods of Quality of Service that are widely used and each has advantages and disadvantages in terms of technical and non technical. In this research will answer the use of the best Quality of Service method on Cisco ISP Router by using descriptive analysis through Quality of Service data analysis parameters. Index Terms— Bandwidth, Quality of Service

Security and confidentiality of data is the central aspect of an information system so that it can only be accessed by the owner of the information or interested user. In sending data, without the existence of a technique of concealing important information, it will be very easy for people who do not have access rights/interests to know the contents of the information. Steganography is the art and science of hiding secret messages in other messages so that the contents of the secret message cannot be traced. In this study, steganography technic is implemented by using the Least Significant Bit (LSB) method, modifying less significant bits or the last bit in one byte of data by using text messages as a storage medium. The purpose of this study was to analyze and design an encryption and decryption simulation for the insertion of text messages in an image by using the steganography algorithm using the Least Significant Bit (LSB) method, so that it would secure the text messages sent by the sender to the receiver by inserting the text message into an image both in the format * .jpg, * .bmp and * .png. The software will be used to simulate steganography using free program (Open Source) Cryptool2 in order to describe the concepts of cryptography and cryptanalysis. Keywords: Steganography, Least Significant Bit (LSB), Cryptool2

Hasil penelitian menunjukkan bahwa presentation format binary menjadi yang tercepat untuk waktu (ms) proses enkripsi dan dekripsi, sedangkan Presentation format base64 menjadi yang terlama untuk waktu (ms) untuk proses enkripsi dan dekripsi. Kata Kunci: Kriptografi, Paillier Cryptosystem, Cryptool2 Abstract. Every day hundreds of thousands of people interact electronically, through e-mail, e-commerce, ATM machines or cell phones. The increase in the dissemination of information electronically has resulted in an increasing dependence on cryptography. One of the roles of cryptography is to secure data by using cryptographic algorithms. The paillier cryptosystem algorithm is an asymmetric probabilistic algorithm for public key cryptography, the paillier cryptosystem algorithm is used because the computation of encryption and decryption in the paillier cryptosystem algorithm is quite complicated, because it requires two power operations, one multiplication operation, and one modulo operation. Thus, the security level of the paillier cryptosystem algorithm is quite good. The purpose of this research is to analyze, design and implement simulation of encryption and decryption of text messages (in the form of text writing or text files) using the paillier cryptosystem algorithm with 4 (four) presentation formats, namely, binary, octal, hexadecimal and base64. Thus text messages (in the form of text writing or text files) will be safer when sent via email, sms or chat from sender to message recipient. The software that will be used to simulate the paillier cryptosystem algorithm uses Cryptool2. The results showed that the binary presentation format is the fastest for the encryption and decryption process time (ms), while the base64 presentation format is the longest for the time (ms) for the encryption and decryption process. Key words: Cryptography, Paillier Cryptosystem, Cryptool2

The development of data and information technology and communication at this time is an important part of everyday human life. Along with the times, the human need for information is increasing. as the development of data and information technology that is increasingly advanced and developing, the internet can no longer guarantee to provide data that is safe enough for its users. Data is very important, so the accuracy of the data is needed in the decision making process. The importance of data values causes the availability of data security, so that data falls precisely and accurately on the right party. In this research a data security simulation will be designed using encryption and decryption methods using the TEA (Tiny Encryption Algorithm) algorithm. In the TEA (Tiny Encryption Algorithm) encryption process, this study uses 64 rounds, where each round consists of, addition, key & data substitution, and XOR. The purpose of this study is to analyze, design and implement TEA (Tiny Encryption Algorithm) algorithm in the form of encryption and decryption simulation of text messages (both text and text files), so that text messages (both text and text files) will be safer when sent via email from the sender to the recipient. Thesoftware that will be used to create a simulation of the TEA (Tiny Encryption Algorithm) algorithm uses Cryptool2, which is an Open Source program used to describe the concepts of cryptography and cryptanalysis. The test results prove that this simulation can secure text messages (both text writing or text files) with different character lengths and keys. The longer and larger the size of the text message (either text or text file) and the key, the longer it will take for the encryption process.
