An important challenge associated with the current massive deployment of Radio Frequency Identification solutions is to provide
security to passive tags while meeting their micro Watt power budget. This can either be achieved by designing new lightweight
ciphers, or by proposing advanced low-power implementations of standard ciphers. In this paper, we show that the AES algorithm
can fit into this micro Watt power budget by combining ultra-low-voltage implementations with a proper selection of the process
flavor in a low-cost nanometer CMOS technology. Interestingly, this approach only requires slight modifications to the standard
EDA tool flow, without incurring the engineering costs of architecture optimizations. In order to demonstrate this claim,
we successfully designed and manufactured an AES coprocessor in a 65 nm low-power CMOS process. We prove with measurement
results obtained from a set of 20 manufactured dies that the proposed coprocessor can be safely operated down to 0.32 V with
an energy per 128-bit encryption/decryption at least 2.75× lower than in previously published low-power AES implementations. |
