ECDSA is a widely adopted digital signature standard. A number of threshold protocols for ECDSA have been developed that let a set of parties jointly generate the secret signing key and compute signatures, without ever revealing the signing key. Thre

We consider applications involving a number of servers in the cloud that go through a sequence of online periods where the servers communicate, separated by offline periods where the servers are idle. During the offline periods, we assume that the se

In this paper, we investigate how existing theoretical contributions on usable security can serve to guide the design of a specific system. We illustrate how going through this theoretically informed, concrete design process, also provides the basis
