Unclonable Encryption in the Haar Random Oracle Model
James Bartusek, Eli Goldin
We construct unclonable encryption (UE) in the Haar random oracle model, where all parties have query access to for a Haar random unitary . Our scheme sati…
A Note on Boosting Uncloneable Encryption in Microcrypt
James Bartusek, Eli Goldin
In this note, we consider the setting of uncloneable encryption satisfying uncloneable indistinguishability, a form of symmetric key encryption that prevents the cloning of ciphert…
On the Communication Complexity of Secure Multi-Party Computation With Aborts
James Bartusek, Thiago Bergamaschi, Seri Khoury +2
A central goal of cryptography is Secure Multi-party Computation (MPC), where parties desire to compute a function of their joint inputs without letting any party learn about t…
Secret Sharing with Certified Deletion
James Bartusek, Justin Raizes
Secret sharing allows a user to split a secret into many shares so that the secret can be recovered if, and only if, an authorized set of shares is collected. Although secret shari…
