Abstract

This paper describes an embedded security coprocessor that consists of four components: an advanced encryption standard (AES) based cryptographic engine, a fingerprint matching oracle, template storage, and an interface unit. Two functionally-identical coprocessors are fabricated using a TSMC 6M 0.18-μm process. The first coprocessor uses standard cells and encrypts at 3.84 Gb/s. The second coprocessor uses wave dynamic differential logic (WDDL) combined with differential routing to combat side-channel information leakage through power analysis attacks. It encrypts at 0.99 Gb/s. The coprocessor is part of a security-partitioned embedded system called ThumbPod.
