W pracy zaprezentowano system typu SoC (System-on-Chip) zrealizowany w układach FPGA wspomagający obliczenia pozwalające na złamanie szyfru opartego na krzywych eliptycznych. Do ataku kryptoanalitycznego wykorzystano algorytm rho Pollarda. System zbudowany jest ze sprzętowych jednostek obliczeniowych HardRho pracujących pod kontrolą procesora NiosII i wykorzystuje interfejs Ethernet do komunikacji zewnętrznej. Omówiona została koncepcja budowy rozproszonego systemu obliczeniowego składającego się z jednostek obliczeniowych będących systemami typu SoC.
Public-key cryptosystems allow secure connections and data exchange through unsafe communication channel without the need of a previous secure key exchange. One of popular cryptosystems used nowadays is Elliptic Curve Cryptosystems (ECC). Cryptanalytic attack on ECC system involves solving the Elliptic Curve Discrete Logarithm Prob-lem (ECDLP). The best known algorithm used to solve ECDLP is Pollard's rho method. So far successful attacks on ECC systems have mostly been based on distributed computer networks. In this paper a hardware cryptanalytic system is presented. The system is implemented in FPGA devices and performs computations of rho Pollard's algorithm. System is based on SoC solution (System-on-Chip) and works under control of a central server in order to form a greater distributed computing system. In the first paragraph of this paper there are presented the aim of work as well as the reasons for choosing FPGA devices and SoC solution. The second paragraph gives the theoretical background [3, 4, 5], explains the basic terms and presents the rho Pollard's algorithm [6, 7]. The third paragraph describes HardRho computation unit HardRho hardware (Fig. 1) and shows differences between the current and recent unit version of unit described in [8, 9]). The fourth paragraph of the paper deals with the SoC solution composed of several HardRho units, NiosII processor and Ethernet communication interface. The system structure (Fig. 2) and internal components [11, 12] are presented. The fifth paragraph is nfocused on the results of implementation and the estimated time of cryptanalysis of an elliptic curve ECC2-89 [1] (Tab. 1). The HardRho unit and [13] are compared (Tab. 2). The obtained results suggest high efficiency of the presented SoC solution. The future investigations and possible optimisation of the system are discussed. - Źródło:
