A Low-Power and Cost-Effective AES Chip Design for Healthcare Devices
2012
Abstract—Information security is very important to health
information, and Cryptography is the key measure for
information security. This paper proposes a low-power and
cost-effective implementation of AES (Advanced Encryption
Standard) supporting encryption and decryption with 128-bit
cipher key. Considering the cost-effective, resource-sharing
scheme is employed to reduce the hardware complexity of the
cipher and decipher. Considering the low-power, we present a
mixed pipelining architecture. The performance is evaluated
on SMIC 0.18um CMOS technology and the throughput
achieves at 800Mbps with the cost of only 17519 equivalent
NAND2 gates, and the power consumption is only 9.7mw.
