TY - JOUR ID - TI - Construct a New System as a Combining Function for the LFSR in the Stream Cipher Systems Using Multiplicative Cyclic Group AU - Mithaq Abdulkareem Abdulwahed AU - Ayad G. Naser Al-Shammari PY - 2018 VL - 59 IS - 3B SP - 1490 EP - 1500 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - In this paper, we construct a new mathematical system as Multiplicative Cyclic Group (MCG), called a New Digital Algebraic Generator (NDAG) Unit, which would generate digital sequences with good statistical properties. This new Unit can be considered as a new basic unit of stream ciphers. A (NDAG) system can be constructed from collection of (NDAG) units using a Boolean function as a combining function of the system. This system could be used in cryptography as like as Linear Feedback Shift Register (LFSR) unit. This unit is basic component of a stream cipher system.
