Abstract
Scalable Encryption algorithm (SEA) is a symmetric block cipher, especially designed for resources constrain systems. SEA proposes low cost encryption routines (i.e. small code size, memory and power), targeted for processors with a limited instruction set. SEA is parametric with text, key and processor size, and allows efficient combination of encryption/decryption and key derivation. SEA was initially designed for software implementations in controllers, smart cards, or processors and small embedded applications. In this paper, we investigate the performance of SEA in a Field programmable gate array (FPGA) device. For this purpose, an iterative loop design of the block cipher is implemented on FPGA. Beyond its low cost performances, the proposed architecture is fully flexible with any parameters and takes advantage of generic VHDL coding. Our efficient modular adders implementation achieves lower area, power consumption and considerably higher throughputs on the target platform VIRTEX-4, xc4vl25 and SPARTAN-3, xc3s1400.
