Authenticated Encryption Schemes on Java Card

Abstract

Authenticated encryption algorithms will be the main workhorse for secret-key cryptography in the future. The ever increasing use of smart cards requires that authenticated encryption schemes are also available on smart cards. In this paper, five authenticated ciphers from the CAESAR competition are implemented and evaluated on Java card platform. The performance and memory footprint are determined for each cipher which is relevant to low compute-power, memory-constrained embedded devices. This work enables availability of authenticated ciphers on Java card. The paper also motivates the case for providing authenticated encryption on cryptographic co-processors of smart cards.
