Reconfigurable architectures provide the user the capability to couple performance typical of hardware design with the flexibility of the software. In this paper, we present the design of AES/Rijndael on a dynamically reconfigurable architecture. We will show a performance improvement of three order of magnitude compared to the reference code and up to 24x speed-up figure wrt fast C implementations over a RISC processor. A maximum throughput of 546 Mbit/sec is achieved. Compared to prior art, we show better energy efficiency with respect to the other programmable solutions, obtaining up to 3 Mbit/sec/mW.
