Cipher Twofish Implementation On Fpga Board

Abstract

This paper deals with nowadays hot topic, which is data security and secure communication. It describes solution which uses Twofish cipher to ensure confidentiality of data. The cipher Is implemented in VHDL language and used on FPGA chip because of execution speed. The teoretical introduction explains need for secure the communication and data. In the next parts Twofish cipher and implementation are being discussed.
