Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The professor concludes the course on discrete mathematics by briefly summarizing its contents and introducing two additional opportunities: a course on foundations of cryptography and an invitation for motivated research scholars to apply for MS and PhD positions in cryptography.
Detailed
In this section, the professor wraps up the discrete mathematics course by reflecting on the concepts covered, such as mathematical reasoning, combinatorial analysis, discrete structures, and their applications in computer science. He also promotes a separate course focused on the foundations of cryptography, emphasizing its relevance in securing data through mathematical techniques. Additionally, he announces the availability of research positions for dedicated MS and PhD students interested in the field of cryptography, clarifying that he does not offer roles for research assistants or interns.

Chapter Content
Apart from the course on discrete maths, I also offer a course on foundations of cryptography. So, you can find the details here and it covers in detail all the foundations for modern cryptography. And as we have seen briefly in this course, cryptography is nothing but a mathematical science to keep your data secure and we had seen some cryptographic applications like key exchange, public key cryptography and so on.
Detailed Explanation
This chunk introduces a course on foundations of cryptography offered by the professor. It highlights that this course provides in-depth coverage of the principles behind modern cryptography. The professor emphasizes that cryptography serves as a mathematical framework designed to safeguard data, and mentions specific cryptographic practices like key exchange and public key cryptography that were touched upon in the current course.
Examples & Analogies
Think of cryptography like a secret code that only you and your friend know. Just like how you might create a special way of writing messages so that no one else can read them, cryptography uses math to safeguard digital information. When you send a message or data online, cryptography ensures that only the intended recipient can decode and understand it.

Chapter Content
In this course, we actually cover in detail, not only encryption, key exchange and so on, we cover the foundations and fundamentals of modern cryptography namely we deal with formal definitions, constructions and detailed mathematical proofs for various cryptographic primitives. And there you will find that the concepts of discrete mathematics that we have learnt in this course are very much useful.
Detailed Explanation
This chunk elaborates that the cryptography course not only discusses practical applications like encryption and key exchange but also dives into theoretical aspects. It focuses on formal definitions, how these cryptographic systems are built, and the mathematical proofs that validate their security. This emphasizes the relevance of discrete mathematics learned in the course, as these concepts underpin much of cryptographic theory.
Examples & Analogies
Imagine building a safe that uses a unique combination lock. The way you construct that lock involves mathematical principles to ensure it is secure against unwanted access. Similarly, in cryptography, every encryption method is designed with specific mathematical rules to ensure the data remains confidential and secure during transmission.

Second advertisement that I am always looking for motivated full time MS and PhD research scholars who want to work in cryptography. If you are interested to work with me, you can apply in response to the advertisements, which come out twice a year. Advertisements are published at this website and I am not interested in research assistant or internship or offering research assistant, internship and project positions.
Detailed Explanation
This chunk states that the professor is seeking motivated individuals for full-time Masterβs and Ph.D. research positions in the field of cryptography. It notes that interested candidates can apply based on advertisements published twice a year. However, the professor makes it clear that he is not looking for research assistants or interns, which delineates the type of engagement he is offering.
Examples & Analogies
Consider a job opening announcement that specifies unconventional roles; itβs like a bakery that is only hiring experienced chefs and not looking for part-time helpers. The professorβs call for serious research candidates reflects a pursuit of knowledge and innovation in cryptography, much like how a bakery seeks expert bakers to create unique recipes.
