Abstract

In this paper we consider some cryptographic implications of integrated circuit (IC) printing. While still in its infancy, IC-printing allows the production and personalisation of circuits at very low cost. In this paper we present two block ciphers PRINTcipher-48 and PRINTcipher-96 that are designed to exploit the properties of IC-printing technology and we further extend recent advances in lightweight block cipher design.
