cAESar results: Implementation of Four AES Candidates on Two Smart Cards
Gaël Hachez, François Koeune, Jean-Jacques Quisquater · 2000
One of the important criteria the future cryptographic standard will have to meet is smart card suitability. However, the information provided in the o#cial submission makes comparison rather di#cult. This paper tries to partially answer this question, by describing our experience in implementing four of the candidates on two smart card: a typical lowcost one and a typical #sophisticated" one. 1 Introduction In the requirements for an AES candidate submission, the NIST asked for an estimation of the performances on an 8-bit platform. This question was answered very di#erently by the 15 candidates. Some completed a full smart-card implementation, while others gave only general estimations of the consequences an 8-bit implementation would imply, or forgot the memory usage question, . . . Anyway, even the full implementations were performed on di#erent smart cards, which makes performance comparison impossible. In view of the increasing importance of smart cards in today's world,...
