A Reorganizable Architecture Based on Registers Heap Connection

This paper discusses a method which can connect and organize reorganizable elements effectively. The architecture is based on the registers heap, and makes the registers heap as the bridge of interconnection among all kinds of the reorganizable elements. It realize five common cipher algorithms such as IDEA,DES,AES, so that it can implement different cryptographical operation, and match different cryptographical methods. The architecture has been tested on the FPGA successfully. The performance and the function can meet the need well, The test and synthesis results show that this idea can improve the flexibility of cipher algorithm design strikingly by fix scale.
