摘要：This paper presents two types of high-speed hardware architectures for the block cipher ARIA. First, the loop architectures for feedback modes are presented. Area-throughput trade-offs are evaluated depending on the S-box implementation by using look-up tables or combinational logic which involves composite field arithmetic. The sub-pipelined architectures for non-feedback modes are also described. With loop unrolling, inner and outer round pipelining techniques, and S-box implementation using composite field arithmetic over , throughputs of 16 Gbps to 43 Gbps are achievable in a 0.25 CMOS technology. This is the first sub-pipelined architecture of ARIA for high throughput to date.
