Pre-Silicon Power Leakage Assessment Framework using Generative Adversarial Networks
No full textAs of 2021, the world economic forum deems cyber-security failures as one of the most potent threats to the world. According to a McAfee report, the cost of cybercrimes in 2020 reached nearly 1 trillion US dollars, which was around 50 percent more than what it was in 2018. Exacerbating the already mammoth financial implication of such a failure is the ever-growing diversity in cyber attacks. Side-channel analysis is one such attack type wherein the information leaked via the implementation of a cryptographic algorithm is leveraged to obtain secret data, rather than any weaknesses in the cryptographic algorithm itself. This leaked information, amongst others, can be in terms of power, EM radiation, or the time taken to perform a cryptographic operation. Countermeasures against such side-channel attacks aim at reducing the amount of information leaked via the side channels or reducing the correlation between the secret operations and the information leaked. Manufacturing the chip is often a prerequisite for evaluating the efficacy of such countermeasures, which is a costly and time-consuming process. Thus, the security evaluation of a design has a substantial impact on the design cost and the time to market. In case the design does not meet minimum security requirements, it has to be redesigned and manufactured, increasing not only costs but also the design time considerably. Hence, there is a need for pre-silicon leakage assessment tools that can provide designers a sense of certainty about the security aspects of their design. However, the existing pre-silicon leakage assessment tools are either deemed unreliable or too slow to be used to perform power leakage assessment, which is the problem this thesis aims to ameliorate. This thesis explores the use of generative adversarial networks (GANs) for generating synthetic power traces. Generative deep learning has been used in various domains like computer vision, audio, and even for medical data like ECG. GANs have been introduced in the context of side-channel attacks to enlarge the size of the profiling dataset for carrying out profiled side-channel attacks. In this work, we propose a robust methodology to condition and train GANs to generate power traces that can be used to carry out leakage assessment. This methodology can even be extended to support the design space exploration of countermeasures by providing reliable leakage assessment at design time. The generated power traces are not only indistinguishable but also as attackable as the real traces. The conditioning technique helps the GAN to generalize to various scenarios and the proposed framework provides a speed-up of around 140 times over traditional CAD methods to simulate power traces while maintaining their structure and accuracy.Computer Engineerin

Functional relations involving generalized H-function
No full textA number of papers have appeared in literature in which certain functional relations associated with hypergeometric functions and Digamma function ψ(z) are derived. In order to unify and extend the existing results due to Kalla [7]. Kalla and Ross [9], Al-Saqabi and Kalla [1], Nishimoto and Saxena [12], Srivastava and Nishimoto [17] and Pandey and Srivastava [14] etc., the author establishes two functional relations between ψ(z) and generalized H -function due to Inayat-Hussain [6]. The results obtained are of general character and provide extension and unification of functional relations of various hypergeometric functions available in literature. Existence conditionsand computable representation of the H -function are also investigated.<br /
The evolving politics of labor standards in Bangladesh: taking stock and looking forward
No full textThis chapter provides a brief history of three or more decades of national and international efforts to improve labor standards for the workers in the garment industry. It concludes by looking forward to what could be done in the future. The author draws on her own research in this field to structure the wider literature on this topic. This chapter argues that any account of achievements and failures in relation to these efforts has to be embedded in the wider context in which the Bangladesh industry emerged and grew because this helps us to understand why its working conditions continue to fall short of international conventions and national regulations. While it faces the difficulties faced by any underdeveloped country with a limited history of industrialization and an industrial working class, Bangladesh has featured particularly prominently in international efforts to promote labour standards in global value chains in the garment sector. It can therefore provide an important case study of the challenges encountered by these efforts when the apparent protectionism of powerful global actors encounter the apparent intransigence of locally powerful actors

Six Sigma Methodologies and its Application in Manufacturing Firms
No full textSix Sigma is a methodology for process improvement as well as a statistical concept that looks for to determine the variation intrinsic in any process. Six Sigma represents process, that is having 3.4 defects per million opportunities. i.e. 99.99966 % of the products from a Six Sigma process are perfect. Firms can impact their sigma level by combining main principles from the Six Sigma methodology into leadership styles, process management, and improvement activities. Main principle of the technique is a focus on the customer. There are many challenges in the implementation of Six Sigma. A well-run manufacturing team can make the entire firm more successful through cost-saving measures, increased quality and a larger inventory of products that the company can market. The Six Sigma objective is to make sure the process has minimum defects(3.4 defects per million chances). Every aspect of the process must be carefully planned and documented in detail in order for manufacturing to go efficiently. The main aspect of Six Sigma for enhancement in the manufacturing industry is to maximize the financial returns
Architectural & circuit level techniques to improve energy efficiency of high speed serial links
No full textHigh performance computing and communication are two key aspects of all information processing systems. With aggressive scaling of silicon technology enabling integration of a large number of transistors in a small area, managing power and thermal reliability has become very challenging. While lowering the power needed for performing computation has been the prime focus for decades, energy consumed for data transfer has recently become a major bottleneck especially in high performance applications. The focus of this thesis is on improving energy efficiency of communication links by exploring design techniques at both the architectural and circuit levels.
In the first part of this work, we propose a time-based equalization scheme to implement transmit de-emphasis in voltage-mode output drivers. Using two-level pulse-width modulation, it overcomes the tradeoff between impedance matching, output swing, and de-emphasis resolution in conventional voltage-mode drivers. A prototype PWM-based 5Gb/s voltage-mode transmitter was implemented in a 90nm CMOS process and characterized across different channels and output swings to demonstrate the effectiveness of proposed techniques. The horizontal/vertical eye openings (BER=) at the ends of 60inch and 96inch stripline channels are 78mV/0.6UI and 8mV/0.3UI, respectively. This transmitter achieves an energy efficiency of 3.1mW/Gb/s while compensating for 16-28dB channel loss, which compares favorably with the state-of-the-art.
In the second part, techniques to improve energy efficiency of a complete transceiver are presented. The transmitter employs a novel partially segmented voltage-mode output driver to lower power consumption in pre-drivers during 2-tap FIR equalization. The receiver implements a low power half-rate clock and data recovery with the proposed ring PLL based multi-phase sampling clock generation in CDR loop and charge-based sampling and deserialization. These techniques are verified using the measured results obtained from a 14Gb/s transceiver prototype. Transmitter achieves an energy efficiency of 0.89mW/Gb/s while securing a 0.36UI sampling time margin with at the end of the channel with 11dB loss at Nyquist frequency. The receiver recovers sampling clock with 1.8 long term absolute jitter while recovering 14Gb/s data at . The receiver achieves an energy efficiency of 1.69mW/Gb/s. Transmitter and receiver share an LC PLL, which achieves 0.605 integrated jitter at 7GHz output with an energy efficiency of 0.5mW/GHz. The transceiver as a whole achieves an energy efficiency of 2.8mW/Gb/s.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2017-12-01The student, Saurabh Saxena, accepted the attached license on 2015-11-16 at 16:11.The student, Saurabh Saxena, submitted this Dissertation for approval on 2015-11-16 at 16:37.This Dissertation was approved for publication on 2015-11-18 at 17:00.DSpace SAF Submission Ingestion Package generated from Vireo submission #8792 on 2016-03-02 at 14:13:10Made available in DSpace on 2016-03-02T21:06:32Z (GMT).
