KT-64: A New Block Cipher Suitable to Efficient FPGA Implementation

Summary This paper proposes a new block cipher called KT-64. We make a cipher using components that are believed secure. The structure of KT-64 is very simple, strong and efficient. We use the controlled substitution-permutation networks (CSPNs) based on controlled elements (CEs) for designing fast block cipher suitable to cheap hardware implementation. Security estimations of KT64 cipher show that proposed cipher is high-level security. The synthesis results for hardware implementation (FPGA) prove that KT-64 is very efficient new cipher.
