Covert adversaries

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


In this chapter, we present protocols for securely computing any functionality in the model of covert adversaries; see Section 2.4 for motivation and definitions of the model. We begin by presenting a protocol for oblivious transfer that is secure in the covert model. We present this protocol mainly for didactic reasons; it serves as a good warm-up for understanding how to prove security in this model. Nevertheless, we stress that more efficient oblivious transfer protocols are known (both for the covert and malicious settings; see Section 7.4 for an example).
