Abstract: Nowadays, it is very important to protect personal information such as documents, images, videos or communication between two devices. It is necessary to use encryption algorithms to achieve such protection. Therefore, cryptography and system security are two very important research areas. Cryptographic hash algorithms represent a class of encryption algorithms used for digital signatures, digital data authentication, user identification, etc. There is ongoing competition for new hash algorithm for the SHA-3 standard that will replace the current SHA-2 standard. We present two SHA-3 candidates, Groestl and JH, in this paper. Both algorithms were implemented on the FPGA chips using minimal chip resources, which is important for devices with limited hardware resources. The details of proposed FPGA implementations of Groestl and JH are given in the paper, along with the comparison of the hardware resources which they require.

Key words: Cryptography, FPGA implementation, hash algorithms, SHA standard.
