Data pegawai adalah satu data penting dan basic pada PDAM Tirta Sanita Sumber, dimana data ini akan terhubung keberbagai system seperti kenaikkan pangkat, penggajian, pelaporan dan tanggungjawab pekerjaan. Untuk melindungi kerahasiaan data pegawai dari orang-orang yang tidak berhak, maka pengelola system informasi dapat melakukan pengamanan data melalui Teknik kriptografi, pada penelitian ini peneliti menggunakan algoritma Electronic Codebook (ECB) untuk mengamankan data pegawai. Berdasarkan hasil penelitian didapatkan hasil bahwa algoritma ECB mampu melakukan enkripsi dan deskripsi data pegawai pada PDAM Tirta Sanita Sumber dengan baik, sehingga data pegawai dapat terlindungi dari orang-orang yang tidak berhak mengetahui. Melalui hasil uji pada 50 data pengujian, didapatkan ketepatan proses enkripsi dan deskripsi sebesar 96%, hal ini didukung oleh tingkat prosentase kepuasan user terhadap kinerja enkripsi dan dekripsi aplikasi sebesar 82%. Sedangkan dari sisi pengujian fungsionalitas keseluruhan aplikasi secara blackbox didapatkan bahwa aplikasi sudah mampu memenuhi segala kebutuhan fungsionalitasnya dengan prosentase sebesar 100% benar

In this paper we introduce a novel block cipher based on the composition of abstract finite automata and Latin cubes. For information encryption and decryption the apparatus uses the same secret keys, which consist of key-automata based on composition of abstract finite automata such that the transition matrices of the component automata form Latin cubes. The aim of the paper is to show the essence of our algorithms not only for specialists working in compositions of abstract automata but also for all researchers interested in cryptosystems. Therefore, automata theoretical background of our results is not emphasized. The introduced cryptosystem is important also from a theoretical point of view, because it is the first fully functioning block cipher based on automata network.

System Data

Recently, Information technology develops rapidly. It is possible for us to get some informationquickly, properly and efficiently. The information technology also has many advantages fo r people. Theneed for information is increasing according to the need of its users. This proves that informationtechnology can make our job easier and it can help us to save our time particularly for the job thatrelated to information and data processin g. With the increasing use of computer technology today, italso brings up some problems. One of them is security and confidentiality problem which is animportant aspect in an information system. Data security is an important thing in maintaining theconf identiality of particular data that only can be known by those who have right. RC6 is a symmetrickey algorithm which encrypts 128 bit plaintext blocks to 128 bit ciphertext blocks. The encryptionprocess involves four operations which is the critical arit hmetic operation of this block cipher. As alegal state, Indonesia has issued a regulation in a form of laws governing information and electronictransaction or commonly referred to UU ITE. Besides, Islam is a religion that comprehensively givesthe guidan ce of life for people. Islam has provided guidance in the various fields ranging from social,politics, economics and various other fields.

AbstractRecently, cryptographic literature has seen new block cipher designs such as , or that aim to be more lightweight than the current standard, i.e., . Even though family of block ciphers were designed two decades ago, they still remain as the de facto encryption standard, with being the most widely deployed variant. In this work, we revisit the combined one-in-all implementation of the family, namely both encryption and decryption of each as a single ASIC circuit. A preliminary version appeared in Africacrypt 2019 by Balli and Banik, where the authors design a byte-serial circuit with such functionality. We improve on their work by reducing the size of the compact circuit to 2268 GE through 1-bit-serial implementation, which achieves 38% reduction in area. We also report stand-alone bit-serial versions of the circuit, targeting only a subset of modes and versions, e.g., and . Our results imply that, in terms of area, and can easily compete with the larger members of recently designed family, e.g., , . Thus, our implementations can be used interchangeably inside authenticated encryption candidates such as , or in place of .
