Security has become a curial aspect in the design and use of computer system and network. Hash functions are used for many applications in cryptography mainly in digital signatures and message authentication code and in network security. Keccak hash function has been submitted to SHA-3 competition. In this paper, has implement "SHA-3 512 bit" hash function and high throughput cone designed to work in high clock frequency dedicated to ASIC (Application-Specific Integrated Circuit) or expensive FPGA (Field-Programmable Gate Array) (virtex-7). The maximum clock frequency supported by the design 267.2MHz.
