This paper is proposed new data crytoblock algorithm based on the private key cryptoalgorithim with existed other cryptography algorithims. Therefore new crytoblock design and simulation using the common Synopsys and ALTERA Max+ PlusII Ver.10.1. As a simulation result, new data crytoblock have gate counting 640Mbps at the 40M hz. We thought that proposed new data crytoblock adapt real time information security.
