Cyber Security Seminar by Dr. Marina Blanton from the University at Buffalo – Title: A Bigger Picture of Secure Multi-Party Computation

17 JULY 2023 from 16:00-17:00
Location: Echo Buiding, Room: Arena / ground floor

Abstract:
Secure multi-party computation is a mature sub-area of cryptography that enables computation over private data. Products utilizing such techniques are now increasingly being built by tech companies for privacy-preserving data analytics and other purposes. For many years, progress in this area has focused on mechanisms for securely performing different operations, i.e., on how to perform secure function evaluation. In this talk, we argue that other aspects of privacy-preserving computation deserve the attention of the research community. They include ensuring the trustworthiness of inputs to the computation, achieving security of linked computations, and selecting functions to ensure that the (authorized) information disclosure from the output is limited. We investigate the last component in more detail on the example of average salary computation, inspired by the Boston privacy-preserving gender gap study carried out in 2015-2017.
