#IIITB #IIITBangalore #RMIT Title: "Every Contact Leaves a Trace": Side-channel and Micro-architectural Attacks on Modern Cryptosystems. 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.
