Abstract: Cryptography plays a vital role in securing e-business and e-commerce transactions. However, in spite of their mathematical robustness when these algorithms are implemented they may leak sensitive information via unintended side channels. The focus of this talk is to provide an overview on these side channels which exist when the ciphers are executed on various platforms: from embedded systems to more general purpose computing systems. To be more precise, we start with an introduction to popular side channels wherein the power consumption of a crypto-device can leak information of the secret key. Subsequently, we illustrate how faults can be catastrophic for the security of cryptosystems. In the later part of the talk, we illustrate how side channels can also be extended to more general purpose computing systems. It is rather ironic, that the advancements in micro-architectures often are responsible for these glaring weaknesses. The talk attempts to elucidate that as crypto-engineers it is prudent to analyze such leakages to develop a holistic understanding of secured systems, and translate the theory to practice.

Abstract: This talk is devoted to discussing the implications of a very elementary technique for proving mod 4 congruences in the theory of partitions. It starts with a tribute to the late Hans Raj Gupta and leads in unexpected ways to partitions investigated by Clark Kimberling, Bulgarian Solitaire, and Garden of Eden partitions.

Biography: Prof. George E. Andrews is currently an Evan Pugh Professor of Mathematics at the Pennsylvania State University, USA. He did his undergraduate studies at the Oregon State University and received his Ph.D. in 1964 at the University of Pennsylvania where his advisor was Prof. Hans Rademacher. During 2008–2009 he was the President of the American Mathematical Society. Prof. Andrews's contributions include several monographs and over 250 research and popular articles on q-series, special functions, combinatorics and applications.He is considered to be the world's leading expert in the theory of integer partitions. In 1976, he discovered Ramanujan's Lost Notebook. His book "The Theory of Partitions" is now the standard reference on the subject of integer partitions. He has advanced mathematics in the theories of partitions and q-series. His work at the interface of number theory and combinatorics has also led to many important applications in physics. Prof. Andrews was an Invited Speaker at the International Congress of Mathematicians in Berlin in 1998. He was elected a Fellow of the American Academy of Arts and Sciences in 1997. In 2003, he was elected a member of the National Academy of Sciences. In 2012 he became a fellow of the American Mathematical Society. He has been given honorary doctorates from the University of Parma in 1998, the University of Florida in 2002, the University of Waterloo in 2004, the SASTRA University in Kumbakonam, India in 2012, and the University of Illinois at Urbana–Champaign in 2014.
