Research of new index generation algorithm based on hash function

With the continuous development of massive data management system, data index generation and management gradually become the bottleneck of massive database. Based on and collision-binding characteristic of BLAKE, this paper developed a new type of index generation algorithm based on BLAKE hash function to avoid index conflict and ensure the uniqueness of the index. BLAKE is one of SHA-3 finalist that is based on ChaCha and takes use of standard HAIFA iterative mode. We designed a reconfigurable architecture which supports three different parameters of G function module of round unit of BLAKE on Xilinx Virtex-5 FPGA. The experimental results show that the proposed design can solve the problem of index uniqueness, having smaller size, higher speed and throughout.
