The field of lightweight cryptography has developed significantly over recent years and many impressive implementation results have been published. However these results are often concerned with a core computation and when it comes to a real implementation there can be significant hidden overheads. In this paper we consider the case of cryptoGPS and we outline a full implementation that has been fabricated in ASIC. Interestingly, the implementation requirements still remain within the typically-cited limits for on-the-tag cryptography.
