Information technology. Security techniques. Data integrity mechanism using a cryptographic check function employing a block cipher algorithm

AbstractSimon and Speck are two block cipher families published in 2013 by the US National Security Agency (NSA). These block ciphers, targeting lightweight applications, were suggested in 2015 to be included in ISO/IEC 29192-2 Information technology—Security techniques—Lightweight cryptography—Part 2: Block ciphers. Following 3.5 years of deliberations within ISO/IEC JTC 1 they were rejected in April 2018. This chapter provides an account of the ISO/IEC standardization process for Simon and Speck.

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.
