Abstract: -Implementation of area and throughput of the main building block (compression function) for two SHA-3 candidates BLAKE and JH hash function. The National Institute of Standards and Technology (NIST) has started a competition for a new secure hash standard. A significant comparison between the submitted candidates is only possible, if third party implementations of all proposed hash functions are provided. The BLAKE family contains the four hash function BLAKE-28, BLAKE-32, BLAKE-48, BLAKE-64 with the bit length of their digests being 224,256,384 and 512 , respectively and JH contains JH-224, JH-256, JH-384, JH-512.We use the proposed block diagram of JH and BLAKE compression function and find fixed size message digest from binary string of arbitrary length. The compression function of BLAKE-256 takes as the input four values chain value(h) , message block(m), salt(s) and counter(t). AES design methodology is used in JH design and the BLAKE hash function HAIFA iteration mode. In this paper FPGA implementation is based on two cryptographic hash function candidates BLAKE and JH. and also compare the functions which is used in JH and BLAKE and then extract the important advantages, limitations, algorithms and design principals of both candidates.
