- ONLINE ASET Colloquium
PCryptography 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 of these side-channels which exist when the ciphers are executed on various platforms: from embedded systems to more general-purpose computing systems. More precisely, we start with introducing popular side-channels wherein the power consumption of a crypto-device can leak the secret key. Subsequently, we illustrate how faults can be exploited. 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 advancements in micro-architectures often are responsible for these weaknesses. The talk attempts to elucidate the need of analyzing such leakages to develop a holistic understanding of secured systems and translate the theory to practice.
