Secure Multi-Party Computation Explained with Skyflow’s Liz Acosta

Partially Redacted: Data, AI, Security, and Privacy

In this episode, we discuss the topic of secure multi-party computation. Since its introduction in the eighties, secure multi-party computation – also known as SMPC – has evolved into a subfield of cryptography for which a variety of protocols have been developed. SMPC is a technique used to allow multiple parties to jointly compute a function on their private inputs without revealing any information about those inputs to the other parties.

Liz Acosta, Developer Advocate at Skyflow, joins the show to explain SMPC and share her recent research into the subject. We begin by explaining the basic concept of SMPC and how it differs from traditional methods of computation.

We also discuss the practical applications of SMPC, such as in the financial industry for secure trading and in the healthcare industry for secure sharing of patient data. We also highlight the challenges that still need to be addressed in the field, such as scalability and ensuring the security of the computation.
