The fifteenth edition of University Distinguished Lecture series on the topic “India at 75 and beyond”, was held on October 29, 2022 to celebrate the magnificent growth displayed by India. The session was addressed by Dr C Rangarajan, renowned economist and former Governor of Reserve Bank of India. The intense and inspiring lecture highlighted the importance of reflection on the past and articulation of our vision for our future to enable rapid progression on economic development.

Dr C Rangarajan gave a comprehensive outlook on the economic performance of India since independence. “India has made momentous progress on reducing multidimensional poverty. The incidents of multidimensional poverty were almost reduced by half to almost 27.5% during 2005-06 and 2015-16 period due to deeper progress among the poorest. Thus within 10 years, the number of poor people in India fell by more than 270 million, a truly massive achievement,” he stated during the lecture.

Dr Rangarajan further expounded on the importance of reform agendas and measures, the subsisting triad of economic policies and the future challenges of progressing into being a developed nation. The lecture was followed by a Q & A session moderated by Dr S Ananda Rao and Dr Erra Kamal Sai Sadharma from the Department Economics.

Prof Kamaiah Bandi, Dean-School of Liberal Arts and Social Sciences applauded Dr Rangarajan on being a unique distinction of shaping and motivating five generations of intellectual cohort. “Dr C Rangarajan has successfully brought down the gap between theory and practice in his capacity as Governor of RBI and various other important positions he has held for our nation. We as SRM AP look forward to your remarkable experience and knowledge to incubate motivation in our students.”

SRM University-AP has actively promoted a cumulative intellectual ecosystem and interdisciplinary education. “The principal objective of the University Distinguished Lecture series is to impel research scholars, students from all around the world to undertake progressive measures for the holistic development of our nation”, said Honourable Vice Chancellor, Prof Manoj K Arora in his welcome address.

Prof D Narayana Rao, Pro-Vice-Chancellor, SRM University-AP concluded the event by addressing Dr C Rangarajan as ‘the modern Kautilya of India’ and presented a memento on behalf of the institution as a token of respect and appreciation for his esteemed presence at the fifteenth edition of the University Distinguished Lecture series.

In the last few years, due to the enormous development in communication technology, the sharing, and transmission of information have increased immensely. The information can be transferred in various forms, such as text, audio, video, and images. Mostly, the information or data is transmitted through open channels, which increases the possibility of illegal interception, fabrication, and modification of the original information. Thus, to avoid unauthorised access or alteration of data, the development of secure transmission systems is very important.

The latest research from the Department of Physics evaluates the security strength of an improved optical cryptosystem based on interference. Assistant Prof Dr Ravi Kumar has published a paper, Security analysis on an interference-based optical image encryption scheme, in the Applied Optics journal, with an impact factor of 1.905.

Dr Ravi Kumar’s research is focused on the area of optical information processing and optical metrology. He studies and designs new optical cryptosystems with enhanced security features. For that, he uses various optical aspects and techniques, such as interference, diffractive imaging, polarization, computational imaging, etc. Alongside this, he also works in the area of digital holography and incoherent imaging. In this, he designs and develops new optical systems for imaging applications, such as super-resolution imaging, biomedical imaging, 3D imaging, telescopic applications, object detection, reconstruction, etc.

Explanation of the Research

Optical systems have been studied extensively for image encryption and found to be more reliable and efficient than their digital counterparts, such as parallel processing, capable of processing 2D data, multi-parameters capabilities (i.e., phase, wavelength, polarization, etc.), and can be employed as the security keys. The usage of biometric authentication in daily life, credit cards, fingerprint authentication, email/bank passwords, etc.; all need to be secured. This research can play an important role in designing a sophisticated cryptosystem for future technologies. Moreover, another direction of the research i.e., optical imaging, can be translated to design new low-cost biomedical devices (endoscopes, microscopes, biomedical sensors, etc.) which can have a significant social impact.

In the future, Dr Ravi Kumar will be focusing on the development of a new robust optical cryptosystem and designing new attack algorithms for existing optical encryption techniques. Additionally, he is also designing new optical imaging systems with better signal-to-noise ratios and improved resolution.

Abstract

In this paper, the security strength of an improved optical cryptosystem based on interference has been evaluated. The plaintext was encoded into a phase-only mask (POM) and an amplitude mask (AM). Since the information of the plaintext cannot be recovered directly when one of the masks is released in the decryption process of an improved cryptosystem, it seems that it is free from the silhouette problem. However, researchers found that the random phase mask (RPM) that served as the encryption key is not related to the plaintext; thus, it is possible to recover the RPM firstly using the known-plaintext attack (KPA). Moreover, the POM and the AM generated in the encryption path only contains the phase and amplitude information, respectively; thus, these can be utilised as additional constraints in the proposed iterative process. Based on these findings, researchers have demonstrated two new kinds of hybrid attacks to crack the cryptosystem, i.e., a KPA and an iterative process with different constraints. To the best of our knowledge, it was the first time that the existence of a silhouette problem in the cryptosystem under study had been reported. Researchers have validated their attacks through numerical simulation.

Intelligent transport systems embedded with latest technology is the future of automotive industry and can revolutionise the very infrastructure and architecture of transportation. The principles of intelligent transportation systems have manifested in the development of Internet of vehicles (IoV), a novel technological network that enables autonomous and connected mobile commutation facility. Dr Sriramulu Bojjagani, Assistant Professor, Department of Computer Science and Engineering, has published a paper on this seminal topic titled “Secure Authentication and Key Management Protocol for Deployment of Internet of Vehicles (IoV) Concerning Intelligent Transport Systems” in the prestigious journal, IEEE Transactions on Intelligent Transport Systems (Q1 journal) having an Impact factor of 9.551. The paper highlights the development and significance of the pioneering AKAP-IoV system in successfully tackling cyber threats and security vulnerabilities.

Abstract

Intelligent transport systems amalgamated with advanced technologies are an important element of the automotive industry, including critical infrastructure and transportation. Internet of Vehicles (IoV) is the modern technological framework designed for intelligent transportation. IoV creates a network of information relations among vehicles, thus contributing to reduced congestion, roadside infrastructure, driver/traveller safety, and traffic efficiency through wireless communication and sensing technology. However, a significant challenge in IoV applications is security, as criminals could potentially exploit these applications. Despite increasing industry awareness, the potential danger posed by security vulnerabilities and cyber threats remains high. In this study, we have designed a new system called AKAP-IoV, which supports secure communication, mutual authentication, and key management among vehicles, roadside units, and fog and cloud servers. AKAP-IoV was tested and verified using Scyther and Tamarin to ensure its resistance to cyber threats. Furthermore, we conducted a formal security analysis using the Real-or-Random (RoR) oracle model to assess security properties logically. In addition, a detailed, comprehensive comparative study was considered to evaluate the performance, functionality, efficiency, and security features supported by AKAP-IoV compared to those of recently developed schemes.

Tropical forests are the breathing lungs of the world that work as a collective to stabilise climate by absorbing vast amounts of carbon dioxide. Covering over 12% of Earth’s total land surface. It functions as a harbour for evolution and supplying prerequisite rainfall for healthy vegetation. Recent global climate changes have catalysed drastic effects on the tropical forests and the healthy functioning of the same. A critical understanding of the present state of forest ecosystems is crucial for undertaking necessary measures to prevent further degradation.

Recently, the project entitled Assessment and modelling of carbon and nitrogen dynamics in tropical forests of Eastern Ghats, Andhra Pradesh in response to climate change, has been sanctioned to Dr Javid Ahmad D, Assistant Professor, Department of Environmental Science by DST – SERB (Science and Engineering Research Board), Govt of India, with a total outlay of Rs. 28.54 lakhs. Dr Javid Ahmad D is the principal investigator of the project.

A complete dataset on long-term dynamics in vegetation, the C and N generated for different tropical forest types in the Eastern Ghats landscape would serve as a baseline data for forest managers and policy-makers. The project aims to gain insight on the response of these tropical forests to changing global climate in relation to multiple factors (elevated CO2, increased temperatures and altered precipitation).
