ICEBERG is a block cipher that has been recently proposed for security applications requiring efficient FPGA implementations. In this paper, we investigate a compact ASIC implementation of ICEBERG and consider the novel application of concurrent error detection to protect the implementation from fault-based attacks. The compact architecture of ICEBERG requires about 5800 gates with a throughput of 552 Mbps in an ASIC implementation based on 0.18 mum CMOS technology. The addition of an effective multiple parity concurrent error detection scheme to protect the hardware from fault attacks results in a 62% area overhead.
