We introduce the notion of associative one-way functions and prove that they exist if and only if P 6= NP. As evidence of their utility, we present two novel protocols that apply ...
This paper presents a formal model for asynchronous distributed systems with servers that may exhibit Byzantine faults or crash and subsequently recover. The model is computationa...
— The Internet’s interdomain routing protocol, BGP, is vulnerable to a number of damaging attacks, which often arise from operator misconfiguration. Proposed solutions with st...
This paper suggests a new building block for cryptographic protocols and gives two instantiations of it. The concept is to generate two descriptions of the same group: a public des...
Collaborative optimization problems can often be modeled as a linear program whose objective function and constraints combine data from several parties. However, important applicat...
