Book Description
As the technology advances day by day, there is an essential need for a secured data transmission for exchanging information from one user to the other. Generally , data transmission techniques are achieved via private/public data networks. The transmission of data through these networks is not secured. Therefore, some kind of safety is needed for information exchange which is accomplished by encrypting the transmitted data. In this research a novel method is used in which hardware implementations of private/secret key encryption standards such as Advanced Encryption Standard (AES), Triple Data Encryption Standard (TDES) and Data Encryption Standard (DES) are integrated in a single silicon die of group centric Secured Information Sharing. This improves confidentiality, integrity and accuracy of the transmitted data. Advanced Encryption Standard is specified by National Institute of Standards (NIST) in 2001 as the specifications for encryption in electronic communication. It is also known as symmetric key algorithm as the encryption and decryption both are formulated using this single standard key. From the family of ciphers NIST selected three members of Rijndael family, each with key length of 128, 192 and 256 bits for each 128 bit block size as AES. For every key length a fixed number of rounds in AES are processed. For 128, 192 and 256 bits, 10, 12 and 14 rounds are executed respectively. In this research, AES 128 bits has been designed and implemented. Triple Data Encryption Standard (TDES) is a cipher algorithm where original Data Encryption Algorithm (DEA) or DES is applied three times. When DES was originally developed, it was sufficient to withstand the attacks using computer power of that era. However, with the remarkable increase in computing power, this algorithm was not complex enough to withstand the brutal attacks. To overcome this problem, Triple DES was proposed to offer high level of security without proposing any novel cipher algorithm. In this research all these three algorithms are implemented in Verilog and TSMC 65nm technology node. Xilinx ISE and Icarus Verilog are used for simulation of AES and DES. Cadence RTL Compiler is used to synthesize the design with minimum area. Finally the Graphic Database System (GDS) II layout of all the crypto cores and Top Module have been generated using Cadence Encounter.

Book Description
Cryptography is one of the leading techniques today for ensuring safety in a communications system. Apart from the military use, the information revolution caused by the recent development of computer science has yielded higher and higher demand for the commercial use of cryptography. As a result many ciphering algorithms have been developed in the past and are being continuously researched. Modern ciphering modules include techniques of implementing these crypto algorithms into them in the form of either hardware or software or both, the end result being a safe and secure communication channel. Looking at the growing research done in this field along with new ways of breaking ciphers, the National Institute for Standard and Technology (NIST) published a standard called the Federal Information Processing Standard (FIPS) in January 1994. The FIPS calls for a uniform pattern that is to be used by federal organizations during the implementation of cryptographic-based security systems that deals with sensitive and valuable data. The standard provides security requirements covering areas related to secure design and implementation of a cryptographic module. It provides four increasing, quantitative levels of security intended to cover a wide range of potential applications and environments. The thesis presents a framework for a Cryptographic Module for wireless sensor nodes complying with FIPS 140-2. The module will be installed on Navy ships along with existing wireless sensor nodes and hence comes the FIPS validation requirement. The module is being implemented on a Texas Instrument MSP430 micro-processor and the IAR embedded workbench programming and compiling. Since the crypto module needs to comply with the FIPS, the ciphering algorithm used is the Advanced Encryption Standard (AES) as it is a FIPS approved algorithm. Given the requirements, the module will be primarily responsible for the I/O of binary data to and from the master controller and ciphering and deciphering of this data using the AES ciphering algorithm along with various authentication and error checking techniques. The presented architecture and hence the crypto module can be used for several other applications except the mentioned use with sensor nodes and can be made commercially available by the company supporting its development.

Book Description
Abstract: Chaos is an interesting phenomenon for nonlinear systems that emerges due to its complex and unpredictable behavior. With the escalated use of low-powered edged-compute devices, data security at edge develops the need for security in communication. The fact that Chaos synchronizes over time for two different chaotic systems with their own unique initial conditions, is the base for chaos implementation in communication. This thesis talks about an encryption architecture suitable for on-chip integration with sensors. This concept provides a POC (proof of concept) that security is encrypted on the same chip with sensors itself. This algorithm is based on Chua’s chaotic system and implemented as Time Scaling Chaotic Shift Keying (TS-CSK). This POC research focuses on different chaotic equations that can be analyzed for encryption. In communication, encryption is being used with the help of microcontrollers or software implementations, which turn up using more power and complex hardware implementation. The small Internet of Things (IoT) devices are expected to be operated on low power and constrained with size. At the same time, these devices are highly vulnerable to security threats, which elevates the need to have low power/size hardware-based security. Since the discovery of chaotic equations, there have been various encryption applications with them. The goal of this research is to take the chaotic implementation to the CMOS level with the sensors on the same chip. This paper focuses on four different chaotic equations and achieves the simulations to find alternative architecture that can further reduce the power and the area. The spice simulation is demonstrated for the complete encryption/decryption architecture with Chua’s chaotic equation. The FPGA implementation is carried out to measure the hardware utilization of previously implemented Lorenz and Chua. The LUT (Look-Up Table) utilization is considered as merit to identify the resource utilization on the FPGA board with the help of the Xilinx System Generation toolbox. To advance the research with the goal of fabricating the circuit with CMOS, the cadence implementation of Chua has been achieved.

Book Description
This book introduces readers to various threats faced during design and fabrication by today’s integrated circuits (ICs) and systems. The authors discuss key issues, including illegal manufacturing of ICs or “IC Overproduction,” insertion of malicious circuits, referred as “Hardware Trojans”, which cause in-field chip/system malfunction, and reverse engineering and piracy of hardware intellectual property (IP). The authors provide a timely discussion of these threats, along with techniques for IC protection based on hardware obfuscation, which makes reverse-engineering an IC design infeasible for adversaries and untrusted parties with any reasonable amount of resources. This exhaustive study includes a review of the hardware obfuscation methods developed at each level of abstraction (RTL, gate, and layout) for conventional IC manufacturing, new forms of obfuscation for emerging integration strategies (split manufacturing, 2.5D ICs, and 3D ICs), and on-chip infrastructure needed for secure exchange of obfuscation keys- arguably the most critical element of hardware obfuscation.
