Comparing low and medium cost computer-based technologies suitable for cryptographic attacks

Abstract

14 páginas, 4 figuras, 10 tablas ; Initially developed for tasks related to computer graphics, GPUs are increasingly being used for general purpose processing, including scientific and engineering applications. In this contribution, we have compared the performance of two graphics cards that belong to the parallel computing CUDA platform with two C++ and Java multi-threading implementations, using as an example of computation a brute-force attack on Hitag2, a well known remote keyless entry application. The results allow us to provide valuable information regarding the compared capabilities of the tested platforms and to confirm that such a weak encryption system could be broken in less than a day with medium cost equipment. ; This work has been partially supported by Ministerio de Econom´ıa, Industria y Competitividad (MINECO), Agencia Estatal de Investigaci´on (AEI), and Fondo Europeo de Desarrollo Regional (FEDER, UE) under project COPCIS, reference TIN2017-84844-C2-1-R, and by Comunidad de Madrid (Spain) under project CIBERDINE, reference S2013/ICE-3095-CM, also co-financed by European Union FEDER funds.
