Secure Computability of Functions in the IT Setting with Dishonest Majority and Applications to Long-Term Security
It is well known that general secure function evaluation (SFE) with information-theoretical (IT) security is infeasible in presence of a corrupted majority in the standard model. ...

On the Efficiency of Classical and Quantum Oblivious Transfer Reductions
Due to its universality oblivious transfer (OT) is a primitive of great importance in secure multi-party computation. OT is impossible to implement from scratch in an unconditional...

On Achievable Rates of the Two-user Symmetric Gaussian Interference Channel
We study the Han-Kobayashi (HK) achievable sum rate for the two-user symmetric Gaussian interference channel. We find the optimal power split ratio between the common and private m...

Increased Resilience in Threshold Cryptography: Sharing a Secret with Devices That Cannot Store Shares
Threshold cryptography has been used to secure data and control access by sharing a private cryptographic key over different devices. This means that a minimum number of these dev...
