SUMMARY:Digital Trust and Security Seminar: YOSO: You Only Speak Once

DESCRIPTION:Join special guest speaker\, Bernardo Magri\, Senior Lecturer
  in the Systems and Software Security group at the University of Manches
 ter\n\nOnline seminar with Q&A and discussion.\n\nAbstract: Imagine a se
 tting where whenever a party in a protocol sends a message\, its IP addr
 ess becomes known\, and it gets immediately killed by the adversary in a
  DoS attack. This implies that in any given protocol a party can only se
 nd a single message at a random point in time. Can we do secure multipar
 ty computation in this setting?\n\nIn this talk we introduce the YOSO MP
 C model that is based around the notion of roles\, which are randomly as
 signed stateless parties that can send a single message for the entire d
 uration of the protocol. We will show how one we can leverage the infras
 tructure of public blockchains to securely YOSO-compute any function wit
 h private inputs.\n\n\nBio: Bernardo Magri is a Senior Lecturer in the S
 ystems and Software Security group at the Computer Science department of
  The University of Manchester. Before joining UoM in December 2021\, he 
 was a postdoc researcher at the Aarhus crypto group at Aarhus University
  (Denmark). His research interests are on the theoretical and practical 
 aspects of cryptography and its applications.\n\n
