Math Club: Coding Theory: Shielding Data from Corruption
On Thursday, March 18th at 4 pm on Zoom, Math Club presents Coding Theory: Shielding Data from Corruption, a presentation by Professor Allison Beemer of the University of Wisconsin - Eau Claire.
Coding theory: shielding data from corruption
Whenever data is transmitted or stored, the information is vulnerable to errors that can be either random or adversarial in nature. The field of mathematical coding theory addresses this by introducing redundancy into information, resulting in encoded data. In this talk, we will introduce some fundamental concepts in coding theory, including measures of reliability and efficiency, as well as an important class of codes called linear codes. Linear codes are widely used in practice, and their symmetry allows us to more easily understand and compute measures of their performance. However, we will see that this same symmetry makes linear codes a poor choice when a powerful adversary can tamper with transmissions. We will discuss the advantages of introducing a small amount of non-linearity in this setting, resulting in codes that can both correct random errors and detect adversarial tampering.

Professor Otaku Lecture
You might also be interested in another presentation on Thursday, March 18th at 5:30 pm in the Ubuntu Room of the Jackie Gaughan Multicultural Center by Professor Sangjin Ryu. Professor Ryu will give this semester’s Professor Otaku lecture, and Professor Ryu will explain shear thickening fluids using “Assassination Classroom” and answer the following question: How Koro-sensei (supermonster teacher) can make his jelly-like body stiffer responding to pressure? The lecture will be given in the hybrid format, so audience can either come to Ubuntu room or join the lecture via zoom (register at http://bit.ly/ProfOtaku).
