文摘It is important to generate random number in cryptography. In this paper, we design Pseu-do-random Bit Generator (PRBG), based on Rijndael with a block length of 256 and a cipher key length of 256 by applying the OFB mode. The random nature and the security have been analyzed. The PRBG is also easy to be realized in application.
