High-speed KATAN Ciphers on-a-Chip

Security in embedded systems has become a main requirement in modern electronic devices. The demand for low-cost and highly secure cryptographic algorithms is increasingly growing in fields such as mobile telecommunications, handheld devices, etc. In this paper, we analyze and evaluate the development of cheap and relatively fast hardware implementations of the KATAN family of block ciphers. KATAN is a family of six hardware oriented block ciphers. All KATAN ciphers share an 80-bit key and have 32, 48, or 64-bit blocks. We use VHDL under Altera Quartus in conjunction with ModelSim to implement and analyze our hardware designs. The developed designs are mapped onto high-performance Field Programmable Gate Arrays. We compare our findings with similar hardware implementations and C software versions of the algorithms. The performance analysis of the C implementations is done using Intel Vtune Amplifier running on Dell precision T7500 with its dual quad-core Xeon processor and 24 GB of RAM. The obtained results show better performance when compared with existing hardware and software implementations.

Fuzzy Inference Procedure for Intelligent and Automated Control of Refrigerant Charging

Fuzzy logic controllers are readily customizable in natural language terms and can effectively deal with nonlinearities and uncertainties in control systems. This paper presents an intelligent and automated fuzzy control procedure for the refrigerant charging of refrigerators. The elements that affect the experimental charging and the optimization of the performance of refrigerators are fuzzified and used in an inference model. The objective is to represent the intelligent behavior of a human tester and ultimately make the developed model available for the use in an automated data acquisition, monitoring, and decision-making system. The proposed system is capable of determining the needed amount of refrigerant in the shortest possible time. The system automates the refrigerant charging and performance testing of parallel units. The system is built using data acquisition systems from National Instruments and programmed under LabVIEW. The developed fuzzy models, and their testing results, are evaluated according to their compatibility with the principles that govern the intelligent behavior of human experts when performing the refrigerant-charging process. In addition, comparisons of the fuzzy models with classical inference models are presented. The obtained results confirm that the proposed fuzzy controllers outperform traditional crisp controllers and provide major test time and energy savings. The paper includes thorough discussions, analysis, and evaluation.

Analysis of Pipelined KATAN Ciphers under Handle-C for FPGAs

Embedded Systems are everywhere from the smartphones we hold in our hands to the satellites that hover around the earth. These embedded systems are being increasingly integrated into our personal and commercial infrastructures. More than 98% of all processors are implanted and used in embedded systems rather than traditional computers. As a result, security in embedded systems now more than ever has become a major concern. Since embedded systems are designed to be low-cost, fast and real-time, it would be appropriate to use tiny, lightweight and highly secure cryptographic algorithms. KATAN and KATANTAN family of light-weight block ciphers are promising cryptographic options. In this paper, a sequential hardware design is developed under Handel-C. Taking a step further, Handel-C's parallel construct is taken advantage of to develop a parallel-pipelined hybrid implementation. Both sequential and parallel-pipelined implementations are tested under Altera Quartus to implement and analyze hardware designs in conjunction with DK Design Suite's Handel-C compiler. The developed designs are mapped to Altera's Stratix II that is one of the industry's highest bandwidth and density FPGAs. The results confirm that using Handel-C can provide faster implementations. The obtained results are promising and show better performance when compared with similar implementations-specifically the developed parallel-pipelined processor.

Reconfigurable Hardware Implementation of the Successive Overrelaxation Method

In this chapter, we study the feasibility of implementing SOR in reconfigurable hardware. We use Handel-C, a higher level design tool, to code our design, which is analyzed, synthesized, and placed and routed using the FPGAs proprietary software (DK Design Suite, Xilinx ISE 8.1i, and Quartus II 5.1). We target Virtex II Pro, Altera Stratix, and Spartan3L, which is embedded in the RC10 FPGA-based system from Celoxica. We report our timing results when targeting Virtex II Pro and compare them to software version results written in C++ and running on a general purpose processor (GPP).

Logic Design

Electronic circuits can be separated into two groups, digital and analog circuits. Analog circuits operate on analog quantities that are continuous in value, whereas digital circuits operate on digital quantities that are discrete in value and limited in precision. In practice, most digital systems contain combinational circuits along with memory; these systems are known as sequential circuits. Sequential circuits are of two types: synchronous and asynchronous. In a synchronous sequential circuit, a clock signal is used at discrete instants of time to synchronize desired operations. Asynchronous sequential circuits do not require synchronizing clock pulses; however, the completion of an operation signals the start of the next operation in sequence. The basic logic design steps are generally identical for sequential and combinational circuits; these are specification, formulation, optimization, and the implementation of the optimized equations using a suitable hardware technology. The differences between sequential and combinational design steps appear in the details of each step. The minimization (optimization) techniques used in logic design range from simple (manual) to complex (automated). An example of manual optimization methods is the Karnough map (K-map). Indeed, hardware implementation technology has been growing faster than the ability of designers to produce hardware designs. Hence, there has been a growing interest in developing techniques and tools that facilitate the process of logic design.

Programmable Logic Arrays

Programmable logic arrays (PLAs) are traditional digital electronic devices. A PLA is a simple programmable logic device (SPLD) used to implement combinational logic circuits. A PLA has a set of programmable AND gates, which link to a set of programmable OR gates to produce an output. The AND-OR layout of a PLA allows for implementing logic functions that are in a sum-of-products form. PLAs are available in the market in different types. PLAs could be stand alone chips, or parts of bigger processing systems. Stand alone PLAs are available as mask programmable (MPLAs) and field programmable (FPLAs) devices. The attractions of PLAs that brought them to mainstream engineers include their simplicity, relatively small circuit area, predictable propagation delay, and ease of development. The powerful-but-simple property brought PLAs to rapid prototyping, synthesis, design optimization techniques, embedded systems, traditional computer systems, hybrid high-performance computing systems, etc. Indeed, there has been renewable interests in working with the simple AND-to-OR PLAs.

High Performance Reconfigurable Computing Systems

The rapid progress and advancement in electronic chips technology provide a variety of new implementation options for system engineers. The choice varies between the flexible programs running on a general-purpose processor (GPP) and the fixed hardware implementation using an application specific integrated circuit (ASIC). Many other implementation options present, for instance, a system with a RISC processor and a DSP core. Other options include graphics processors and microcontrollers. Specialist processors certainly improve performance over general-purpose ones, but this comes as a quid pro quo for flexibility. Combining the flexibility of GPPs and the high performance of ASICs leads to the introduction of reconfigurable computing (RC) as a new implementation option with a balance between versatility and speed. The focus of this chapter is on introducing reconfigurable computers as modern super computing architectures. The chapter also investigates the main reasons behind the current advancement in the development of RC-systems. Furthermore, a technical survey of various RC-systems is included laying common grounds for comparisons. In addition, this chapter mainly presents case studies implemented under the MorphoSys RC-system. The selected case studies belong to different areas of application, such as, computer graphics and information coding. Parallel versions of the studied algorithms are developed to match the topologies supported by the MorphoSys. Performance evaluation and results analyses are included for implementations with different characteristics.
