The cipher Rijndael,which has been chosen by NIST as the AES,has a very wider foreground.A detailed description of the key schedule is presented.Under the condition that the block and the cipher key have different combinations,a configurable dynamic design is described,which is implemented efficiently by FPGA on the basis of an analysis of some vital factors.The structure can incarnates agility of the cipher Rijndael adequately.
