SUMMARY:Trust in an Untrusted World: Private Access over Public Infrastructures by Prof. Divy Agrawal
DESCRIPTION:Abstract: \nWe are living in an era where our digital lives are increasingly interdependent\n\nand deeply interconnected. These connections rely on a vast\, layered ecosystem of\nactors—many of whose trustworthiness is uncertain or outright suspect. Over the past three\ndecades\, rapid advances in computing and communication technologies have brought\nunprecedented access and connectivity to billions of users. Yet this digitization comes at a cost:\nour interactions\, queries\, and data are increasingly vulnerable to privacy violations. Today\,\nthreats to privacy come not just from malicious individuals\, but also from powerful\ninstitutions—ranging from service providers to nation-states.\n\nIn this reality of an untrusted world\, we pose several foundational research questions: (i) Can\nwe design a scalable voice communication system that ensures absolute privacy? (ii) Can\nwe build an oblivious search engine over public document repositories? (iii) Can we develop\nscalable private query processing over shared or public databases? (iv) And in the age of\nlarge language models\, can we enable private inference for user queries? These are not just\nopen problems — they are essential challenges if we are to build trusted services over\nuntrusted infrastructures. In this talk\, I will present recent work that leverages Homomorphic\nEncryption to address some of these questions. We explore the inherent performance and\nscalability trade-offs in enabling private access\, search\, and inference. If nothing else\, our\nresults underscore a critical insight: ensuring privacy at scale is not impossible\, but it\ncomes at a high cost.
